This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

Paper title:      “Influences of Climate Change and Human Activities on NDVI Changes in China”

Authors:         Yu Liu, Jiyang Tian, Ronghua Liu, Liuqian Ding

Current climate change, mainly caused by anthropogenic factors, has a variety of impacts on nature and society. The study of the effects of climate change is at the focus of modern climate science, ecology, economics and other disciplines. The peer-reviewed article devoted to the study of the influence of climate change and human activities on such indicators as the Normalized Difference Vegetation Index (NDVI) and the Standardized Precipitation Evapotranspiration Index (SPEI) seems to be important and relevant.

The peer-reviewed manuscript is fully consistent with the scope of “Remote Sensing”.

The statement of the problem, the method of its solution, the analysis and presentation of the results look quite correct and convincing. The literature review is quite representative and relevant. From my viewpoint, the paper is almost ready for publication.

Comment: Since the title of paper mentions “Climate Change”, the authors must include the paragraph in which the essential features of climate change in different parts of China are considered and discussed. Without that the paper looks incomplete.

Reviewer 2 Report

The article Influences of Climate Change and Human Activities on NDVI 2 Changes in China is focus on using NDWI and SPEI index for identify the relationships among vegetation, climate change, and human activities in China.

In order for the article to be published, it should be improved. Some recommendations are:

Q1. For figure 1 a. In the legend you put "Nine River Basin". Only River Basin should be left because on the maps you put a label with the name of each river basin.

For Figure 1. (b) mean annual standardized precipitation ‒ evapotranspiration index (SPEI) and its grid point position from 1998–2017; add label for the 9 river basins. The same comment is valid for fig. 1. c, f, e.

Q2. For Figure 3 I recommend adding at least 5 names of large cities, known on the map for better orientation for article readers.

Q3. The same observation is valid for the maps in Figure 5.
