1. Introduction
In China, traditional villages refer to villages that were formed early, have important historical, cultural, scientific, artistic, economic, and social values, possess rich traditional culture and natural resources, and should be protected [
1]. Traditional villages have both material and intangible cultural heritage characteristics and are an important heritage of China’s agricultural civilization [
2]. However, with the development of multiple construction activities such as urbanization, new-rural construction, and rural tourism, many traditional villages are gradually disappearing. Therefore, giving sufficient attention to traditional villages and carrying out reasonable protection and utilization of traditional villages is of great significance for promoting sustainable and coordinated development between urban and rural areas.
The Chinese government’s attention to traditional villages began in the 1990s, when traditional villages were known as ancient villages. In 1999, China held the first China Ancient Village Protection and Development Technology Forum. In 2003, China established a system for protecting historical and cultural villages. In 2012, China officially began to establish a traditional village directory protection system. As of 19 March 2023, six batches of Chinese traditional village lists have been announced, and a total of 8155 villages in China have been listed as national-level traditional villages [
3]. To explore how to promote the protection and development of traditional villages, scholars in various fields have also begun to conduct extensive research. Scholars in the fields of architecture and planning mainly focus on the research of traditional village site selection, village functions, living environment, architectural design, spatial form, landscape characteristics, and element layout [

8]. Scholars in the fields of archaeology and cultural studies focus on the value recognition of traditional villages, the reconstruction of village style, the inheritance of traditional village culture, and the protection and utilization of village cultural heritage [
9,
10,
11,
12]. The field of agricultural economics focuses on researching the agricultural development model, land use model, and sustainable development of rural economy in traditional villages [
13,
14,
15,
16]. The field of tourism mainly focuses on rural tourism, with research directions including the development and utilization of tourism resources in traditional villages, factors affecting the development of tourism in traditional villages, and the impact of tourism on the protection and development of traditional villages [
17,
18,
19,
20]. The field of geography focuses on the spatial distribution, geographical differentiation, cultural landscape, type zoning, spatiotemporal evolution process, and corresponding influencing factors of traditional villages from a geographical spatial perspective [
21,

24,
25].
As we all know, the level of economic development and urbanization in Zhejiang Province ranks among the top in China. At the same time, 701 traditional villages in Zhejiang Province have been selected for the National Traditional Village List in China, ranking fourth among all provinces in China. That is to say, while emphasizing economic development, Zhejiang Province also attaches great importance to the protection of traditional villages. It is evident that conducting research on traditional villages in Zhejiang Province is of great significance. Therefore, the purpose of this study is to explore the spatial distribution characteristics of traditional villages in Zhejiang Province, and to classify them into different types, laying the foundation for proposing corresponding protection and development strategies for each type of traditional village according to local conditions, thereby more effectively promoting the sustainable development of traditional villages.
2. Literature Review
Studying the spatial distribution and influencing factors of traditional villages is an important basis for rational planning and protection of traditional villages. Therefore, many scholars have conducted research on the spatial distribution and influencing factors of traditional villages. At present, in terms of the spatial scope of such research, some have been conducted nationwide, analyzing and exploring the distribution patterns of traditional villages throughout China [
26,
27,
28]. There are also studies conducted on a specific province, city, or geographical region, such as selecting Guangxi Province [
29], Shaanxi Province [
30], Hebei Province [
31], Fujian Province [
32], Qinghai Tibet Plateau [
33], Henan Yellow River Basin [
34], and the Southwest area of China [
35] as research areas. The studies above have found that traditional villages always exhibit dense distribution and unbalanced spatial distribution. In addition, such studies have summarized that natural factors that affect the spatial distribution of traditional villages mainly include terrain, climate, hydrology, soil, vegetation, animals, natural disasters, etc., as they are often the fundamental factors that determine the location and layout of traditional villages. The selected humanistic factors cover a wider range, including economic development level, political policies, local culture, historical background, population composition, transportation conditions, urbanization level, etc., as these factors not only affect the location and formation of traditional villages, but also affect the continuation and development of traditional villages [
36,
37,
38,
39,
40,
41,
42].
In terms of research methods, since Liu, D. et al. introduced spatial analysis methods into the study of traditional village spatial distribution patterns in 2014 [
21], more and more scholars have begun to use spatial analysis methods including Moran’s I index, local correlation index Getis Ord Gi*, average nearest neighbor index, imbalance index, geographic connectivity rate, kernel density analysis, etc., to analyze the spatial distribution characteristics of traditional villages. In addition, standard deviational ellipse has been introduced to visualize the directional distribution and changes of traditional villages [
43,
44,
45]. At the same time, relevant functions of software such as ArcGIS 10.2, SPSS 26, Stata 17 etc., are used to analyze the factors affecting the spatial distribution of traditional villages. Some scholars also use geographic detectors or construct geographic weighted regression models to explore the comprehensive impact of various factors and determine the degree of influence of each factor [
46,
47,
48]. However, it can be seen that there is relatively little research on the spatial distribution and influencing factors of traditional villages in Zhejiang Province. Therefore, this article takes Zhejiang Province as an example to explore the correlation between the spatial distribution of traditional villages in Zhejiang Province and various geographical factors.
Studying the type characteristics of traditional villages also has important practical significance. Its purpose is to determine the commonality and particularity between each type of village through the classification of village types, thereby revealing the formation and development process of various types of villages and formulating relevant strategies to promote the healthy and sustainable development of villages. British anthropologist Ahern divided traditional Chinese villages into single-surname villages and multi-clan villages according to their clan organization [
49]. Hill applied GIS analysis methods to the study of village types and summarized six spatial distribution types of rural settlements: agglomeration, random, regular, low-density, high-density, and linear through analysis, which has certain pioneering significance [
50]. Chen, J. et al. measured the potential for rural development and divided administrative villages in Shapingba District, Chongqing, into four types: core planning area, important planning area, overall planning area, and basic control area [
51]. Dai, L. et al. classified traditional villages in Gaochun District into five types based on their development level and degree of reconstruction: characteristic protected villages, suburban integrated villages, agglomeration and upgrading villages, improvement and development villages, and relocation and merger villages [
52]. Huang, L. et al. classified traditional villages into agricultural, commercial, transportation, defensive, religious, and secluded types based on their functions [
53]. In addition, some scholars have conducted research on the zoning type of traditional villages from the perspectives of traditional village cultural landscape, architectural structure, spatial layout, etc., with the purpose of classifying the various elements contained in traditional villages, dividing the distribution areas of traditional villages based on their similarities and differences, and studying the protection and development of traditional villages within each area [
54,
55]. However, it can be seen that there is currently very little research on the classification of traditional villages throughout Zhejiang Province. Therefore, this study aims to classify traditional villages in Zhejiang Province into different types and different distribution areas to protect and develop traditional villages in a targeted manner.
Based on the background information above, this study focused on 701 national-level traditional villages in Zhejiang Province. Firstly, spatial analysis methods such as average nearest neighbor index, imbalance index, kernel density analysis, and standard deviational ellipse were used to explain the overall spatial distribution characteristics of traditional villages in Zhejiang Province. Then, based on the actual geographical situation of Zhejiang Province, five geographical elements were selected to explore the correlation between the spatial distribution of traditional villages in Zhejiang Province and these elements: altitude, terrain undulation, river system, county-level administrative center, and main roads. Finally, cluster analysis methods were used to classify traditional villages in Zhejiang Province into different types and distribution areas. It is hoped that through these analyses, valuable references could be provided for the protection and development of various traditional villages and their distribution areas, as well as for the sustainable development of traditional villages in other regions.
5. Discussion
This study first analyzed the overall spatial distribution characteristics of traditional villages in Zhejiang Province. Then, based on the actual geographical characteristics of Zhejiang Province, the relationship between the spatial distribution of traditional villages in Zhejiang Province and the five geographical elements of altitude, terrain undulations, water systems, county-level administrative centers, and main roads was explored. Then, taking into account the comprehensive influence of these geographical factors, traditional villages in Zhejiang Province were divided into five types. Finally, taking into account the spatial distribution characteristics of various types of traditional villages, the distribution areas of traditional villages in Zhejiang Province were classified into six categories. We will now discuss the main findings, contributions, and inspirations of this study.
Firstly, similar to many existing research results on the spatial distribution of traditional villages [
27,
42,
45,
47], the spatial distribution of traditional villages in Zhejiang Province also exhibits characteristics of clustered and unbalanced distribution. The concentration of traditional villages in Zhejiang Province is relatively high in the southwest region, while it is relatively low in other regions. There are three main agglomeration centers for traditional villages in Zhejiang Province, located in the northern and southern parts of Lishui city, as well as the border area between Jinhua and Hangzhou. These phenomena gives us the inspiration that different protection and development strategies should be implemented for different regions with varying levels of traditional village density.
Secondly, the correlation between different geographical elements and the spatial distribution of traditional villages in Zhejiang Province is not the same. The results show that traditional villages in Zhejiang Province have high hydrophilicity, with most of them distributed near river systems, and this result is similar to some studies [
29,
31,
33]. However, the results show that traditional villages in Zhejiang Province are mainly distributed in areas with an altitude of 0–200 m, and the distribution quantity shows a decreasing trend with increasing altitude, which is inconsistent with some existing results. For example, traditional villages in Hebei and Fujian provinces are mainly distributed in hilly and low mountain areas with an altitude of 200–1000 m [
31,
32]. In addition, traditional villages in Zhejiang Province are mainly distributed in areas with moderate terrain undulation of 20–200 m, and similarly, they are mainly distributed in areas a moderate distance away from county-level administrative centers. If the terrain undulation is too low or too high, or the distance from the county-level administrative center is too close or too far, it is not conducive to the preservation of traditional villages. This is also different from the conclusions of some studies that traditional villages generally have lower terrain undulations and are generally far from administrative centers [
26,
38]. In addition, traditional villages in Zhejiang Province are more distributed in areas close to main roads but with sparse road networks, indicating that areas with a certain degree of transportation conditions but not particularly developed transportation conditions are more conducive to the preservation of traditional villages. This is also different from some studies that suggest that traditional villages are distributed far away from roads [
30,
48]. In summary, the above phenomena also give us the inspiration that, due to the different impacts of different geographical elements on traditional villages in different regions, when protecting traditional villages, it is necessary to consider the comprehensive impact of various geographical elements according to local conditions.
Thirdly, based on the comprehensive impact of various geographical elements in the geographical environment where traditional villages are located, we divide traditional villages in Zhejiang Province into five types as shown in
Table 9. Each type of traditional village has different development scales, resource endowments, and development values. Therefore, corresponding protection and development strategies can be proposed based on these characteristics. Finally, taking into account the spatial distribution characteristics of various traditional villages in Zhejiang Province, we have divided the distribution of traditional villages in Zhejiang Province into six categories, as shown in
Table 10, in order to implement specific protection and development strategies for these regions.
6. Conclusions
This study used the average nearest neighbor index, imbalance index, kernel density, and standard deviational ellipse to analyze the overall spatial distribution characteristics of traditional villages in Zhejiang Province. Then, based on the actual geographical characteristics of Zhejiang Province, the relationship between the spatial distribution of traditional villages in Zhejiang Province and the five geographical elements of altitude, terrain undulations, river systems, county-level administrative centers, and main roads was explored. Then, based on the comprehensive influence of various geographical elements in the geographical environment where traditional villages are located, traditional villages in Zhejiang Province are divided into five types: flat-land type, mountainside type, valley type, mountaintop type, and coastal type. Finally, based on the spatial distribution and type characteristics of traditional villages in Zhejiang Province, the distribution areas of traditional villages in Zhejiang Province are classified as follows: the distribution area of flat-land-type traditional villages; the distribution area of flat-land-type and valley-type traditional villages; the distribution area of coastal-type traditional villages; the distribution area in which multiple types of traditional villages are densely distributed; the distribution area of mountainside-type traditional villages; and the distribution area in which valley-type, mountainside-type and mountaintop-type traditional villages are sparsely distributed.
Based on the discussion and conclusion above, we propose the following suggestions for the protection and sustainable development of traditional villages: Due to the unbalanced distribution of traditional villages, different protection and development strategies should be implemented for different regions. For example, in the northern Zhejiang region, where the number of traditional villages is relatively small, traditional villages should be the core to create a comprehensive traditional village tourism scenic area. For the southern Zhejiang region with many traditional villages, it is necessary to enhance the connection between traditional villages and build a traditional village tourism industry chain based on the beautiful landscape environment. Due to the varying impacts of different geographical elements on traditional villages in different regions, it is necessary to pay attention to the comprehensive impact of various geographical elements when protecting and developing traditional villages. Due to the different types of traditional villages in different distribution areas, and the different characteristics of different traditional village types, it is necessary to protect and develop traditional villages according to their types and local conditions.
Although this study has achieved the above mentioned results, there are still some limitations. The research object of this study is national-level traditional villages in Zhejiang Province, and it is hoped that future research can also select some provincial-level traditional villages for research. Only five geographical elements were selected to analyze their correlation with the spatial distribution of traditional villages. It is hoped that more elements can be selected for analysis in future research. The distribution of traditional villages is dynamic, and this study only studied their spatial distribution. It is hoped that in the future further research can be conducted on their spatio–temporal evolution process.
