Special Issue Information

Dear Colleagues,

A Special Issue on the theory and technology of watershed ecological restoration, in the International Journal of Environmental Research and Public Health, is being organized. For detailed information on the journal, I refer you to https://www.mdpi.com/journal/ijerph.

The 21st century is a century in which humankind really needs to rethink on our relationship with nature. At present, the precious buffers for humankind's future survival, development and adaptation to global change are shrinking rapidly. It is urgent for us to start from the concept of ecological protection and explore ecological technological solutions.

Due to human activity in size and strength, improving the social-economic system has deeply influenced watershed resource systems and ecological systems. The important goal of the protection and restoration of the watershed is to maintain and enhance the regional ecosystem services. Watershed ecosystems include various environmental elements such as mountains, rivers, forests, farmlands, lakes, and grasslands. Based on the analysis of ecological-environmental conditions, and the importance of regional ecological functions of the watershed, propose the ecological security pattern composed of the river, riparian zones, and ecological barriers to related threats, such as river pollution, riparian hillside soil erosion, forest barriers, and biodiversity degradation. Reflecting the integrated and systematic requirements and intrinsic logic for watershed protection and restoration, and provides referable indices and quantitative analysis methods for identifying the important areas of watershed ecological protection and restoration, as well as thoughts and ways for constructing ecological security patterns at the watershed scale to realize the systematic protection and restoration of the ecosystem.

Researchers and practitioners in this field have also been looking at advances in watershed ecological restoration, including theoretical systems, technique systems, method systems and multiscale-restoration patterns. Developing strategies for reducing the risk factors, the acute and long term environmental damages, and understanding the cost of watershed ecological restoration in terms of the value realization of ecological products and enhancing the regional ecosystem services.

This Special Issue is open to the subject area of Theory and technology of watershed ecological restoration. The keywords listed below provide an outline of some of the possible areas of interest.

As a policy, protected green space in the rapidly developing the Chang-Zhu-Tan Urban Agglomeration is of great practical significance to study the vegetation changes and influencing factors in the Green Heart area. In this paper, data processing, grading and area statistics were carried out for the maximum value of normalized differential vegetation index (NDVI) from 2000 to 2020. Combined with Theil–Sen median trend analysis and Mann–Kendall, the change trend of long-time series NDVI was studied, and investigation of NDVI influencing factors, processes and mechanisms using geographical detectors. The results showed that: (1) The spatial distribution characteristics of NDVI in the study area were high in the middle and inlaid transition between adjacent grades. Except for the low grades, the distribution of NDVI in other grades was relatively scattered, and the overall trend of NDVI change was rising. (2) Population density was the main factor affecting NDVI changes, with an explanatory power of up to 40%, followed by elevation, precipitation and minimum temperature. (3) The influence of influencing factors on the change of NDVI was not the result of independent action of a single factor, but the result of the interaction between human factors and natural factors, and the factor combinations with greater interaction had significant differences in the spatial distribution of NDVI.

Building a harmonious relationship between human society and river ecosystems has attracted much attention from both government officials and the academy community. Based on the perspective of social-ecological systems (SES), taking the Carp Brook (located in northern Fujian Province, China) as an example, the construction and maintenance of a time-honored artificial river ecosystem was investigated, and its ecosystem services were analyzed. Findings show that the Carp Brook was constructed through a series of ecological engineering, including a transformation of the river channel, building a stable habitat, and breeding carps. The carps have been protected effectively by some folk customs, such as village regulations and folk belief. Meanwhile, the water quality has been maintained through some engineering and institutional measures, which were completed by the local government and villagers. Furthermore, some cultural elements with local characteristics have been formed during the long years of coexistence between human society and the Carp Brook. Based on a healthy ecosystem and abundant culture elements, the Carp Brook provided continuous ecosystem services to human society for more than 800 years, including regulation services (e.g., water purification and flood control) and cultural services (e.g., tourism, research and education, inspiration). Major enlightenments from the Carp Brook are: (a) the Chinese traditional view of nature is important for the construction and maintenance of an artificial ecosystem; (b) traditional folk customs have a strong binding force regarding the protection of the ecosystem; and (c) the choice between material and immaterial services should be made carefully.

Watershed ecology restoration is the key to solving the ecological and environmental problems of watersheds and achieving sustainable development. As one direction of the frontiers of ecology, landsenses ecology is supported by science and technology and cares for humans. It has a great significance for enhancing the human habitat and achieving sustainable development. Combining landsenses ecology and the technical process of watershed ecology restoration allows the integration of people’s visions into the system of strategies and applied technologies for watershed ecology restoration while ensuring the restoration of the ecological functions of watersheds. It is a complement to the traditional ecosystem restoration model. This study establishes the connection between landsenses ecology and watershed ecology restoration in terms of goals, models and focus of attention. It aims to construct an indicator system of restoration with the application of landsenses ecology, form a complete process of ecological restoration with the integration of landsenses ecology and apply it to the ecological restoration of watershed elements with relatively intensive human activity such as urban green areas, buildings and wetlands (rivers and lakes). Rather than just always emphasizing natural ecology, landsenses ecology treats human beings as part of nature. It tries to establish a more comprehensive, humanized ideal restoration model by taking “human perceptions” into consideration. Through a restoration process based on long-term and continuous coordination, feedback and improvement, it can improve the ecological benefits of the watershed and improve residents’ well-being, so as to ultimately realize the establishment of a “community of life between man and nature”.

In order to achieve a comprehensive evaluation of the environmental impact of ecological restoration projects (ERP) under the current destruction and restoration of coastal ecological areas, this paper takes into account the impact of positive and negative indicators on the environment; analyzes the positive and negative benefits of ERP; and establishes a comprehensive environmental impact index system for marine ERP from ecological, economic, and social perspectives through the DPSIR model. On this basis, the cloud model and Monte Carlo simulation are used to obtain the comprehensive assessment grade of the construction period, short-term operation, and long-term operation in the project life cycle. The results show that the benefits of ERP, considering the impact of negative factors, are significantly reduced, and the benefits of ERP will increase remarkably in the long-term operation period. In engineering practice, the environmental pressure factor caused by excessive human activities during construction and operation periods is a key negative factor affecting the overall benefits of ERP. For project decision makers and other stakeholders, the comprehensive assessment grade considering negative impacts is more practical. At the same time, decision makers should take active response measures in the framework of long-term sustainable development, set a tolerance threshold for negative pressure indicators, and strengthen the management of ERP.
