Study and Prediction of Surface Deformation Characteristics of Different Vegetation Types in the Permafrost Zone of Linzhi, Tibet

Round 1

Reviewer 1 Report

Congratulation of your great research. Not much research done in surface deformation characteristics at permafrost zone as you did. You can show your great findings in this manuscript. However, your paper will be more sounding if you can add more statements to your text, as appears in my comments in attached file. Good Luck!!

Reviewer 2 Report

General comments:

In this paper, the author firstly used the Sentinel 1-A data from 2018 to 2021 to analyze the surface deformation , and the surface deformation data of the study area in this period were obtained by two InSAR technologies. Combined with NDVI, the distribution characteristics of the deformation area were analyzed, and then the Holt winters model was used to predict the surface deformation of the study area in the next two months. The article has some practical significance, but the language is poor and the drawing is rough. In addition, there are still some problems that need to be modified.

 

Suggestions:

(1) The language of this paper needs to be improved by a native speaker. There are many grammatical errors, such as:

P1, L12>>>>The article "the" is missing before “Sentinel1-a images”.

P1, L13>>>>“As data” should be deleted .

P1, L16>>>> The method adopted in this paper is an existing method, which has not been improved, and it is inappropriate to use “introduction”.

P1, L16>>>>“would continue to rise” should be written as “will keep rising”

(2) Each subfigure was not numbered in Figure 1.

(3) The full point is missing after the citation "xx et al" in the whole text.

(4) Please add the significance of selecting this rectangular area as the research area in the appropriate place in the text.

(5) Variable letters should be italicized, such as equation (1).

(6) Figure 2 and 3 need to be beautified，and the “illustrates” in the figure title should be written to “Illustrates”

(7) The fonts of longitude and latitude in Figure 4 and 5 are too small, and the directions on the left and right sides should be changed to vertical.

(8) The unit is missing in Figure 6. And some letters in the figure are difficult to see and the composition is poor in aesthetics.

(9) Figure 7 is also a rough and clumsy figure.

(10) All the pictures of this manuscript should be redrawn to improve the quality of the paper.

Reviewer 3 Report

This is an interesting study that exploits the correlation between surface deformation characteristics and vegetation types in permafrost regions. However, there are lots of writing irregularities and formatting errors in the paper.

There is little content about climate change in the article, so I think removing the keyword climate change is better.

The Figure 1. Location of the study area and distribution of permafrost and vegetation for the study area is ambiguous and cannot accurately express the exact location and surrounding environment of the study area. It is necessary to add latitude and longitude, the text in the picture is too small to be clear.

Figure 6, Table 1 and many other charts do not have units. The monitoring results of the two methods in Figure 4 and Figure 5 should indicate the monitoring time period. In addition, the two monitoring results are quite different. Figure 6 cannot effectively solve the problem of the large difference between the results between Figure 4 and Figure 5. The deformation monitoring accuracy has a strong relationship with terrain, interference phase, backscattering ability of ground objects, coherence, atmospheric correction, etc, there is no expression that can characterize these indicators in this paper. In addition, the interferometric phase accuracy in the vegetation area is low, and the author did not develop a new interferometric method to improve the deformation monitoring accuracy of the interferometric radar in the vegetation area, resulting in a large difference in the deformation monitoring results of the two time-series interferometric radar methods.

The article does not clearly explain why two time series analysis methods, ARIMA and Holt-winters, are used, and the reliability verification of the  time series analysis methods is not enough.

Round 2

Reviewer 2 Report

The author has considered all my suggestions, and the integrity and aesthetics of the manuscript hs been improved in a certain extent. Before considering publication, there are several issues that still need the author's attention.

(1) In order to facilitate reviewers to view the traces of modification, all modified contents in the manuscript should be marked.

(2) The language of the article has not been improved significantly. Except for the grammatical problems I mentioned, the language of the full text should also be further improved.

(3) The author has modified all the pictures, but there are still places worth improving. For example, the font color in Figures 8, 10, 12, 13, 14, 15, 16 and 18 should be changed to black. It is suggested that the font of the full text should be "Arial" or "Times New Roman"
