Spatial–Temporal Evolution and Prediction of Habitat Quality in Beijing–Tianjin–Hebei Region Based on Land Use Change
Round 1
Reviewer 1 Report
The paper is interesting and well presented however some figure are not easy to read so I suggest:
- Figure 1. In the first map I do not understand the three colors. What did you highlight in Beijing-tianjin-hebei administrative territorial entity?Write it in caption.
-Figure 2. The fourth map is unreadable. Try to enlarge all 4 maps or separate the last one and enlarge it.
-Figure 3. It is not clear enough. Explain better it in the caption too.
-Figure 6. The labeling of the x and y axes is cut off
- Figure 8. Enlarge it

Point 1: Figure 1. In the first map I do not understand the three colors. What did you highlight in Beijing-tianjin-hebei administrative territorial entity?Write it in caption.
Response 1: Beijing- tianjin- hebei administrative territorial entity. The left picture shows chinese administrative division, and the green area in the picture symbolizes Hebei Province; Pink symbolizes Beijing; Yellow symbolizes Tianjin.
Point 2: Figure 2. The fourth map is unreadable. Try to enlarge all 4 maps or separate the last one and enlarge it.
Response 2: 201 lines and 202 lines of pictures have been enlarged.
Point 3: Figure 3. It is not clear enough. Explain better it in the caption too.
Response 3: Figure 3. Transformation of six land use types in Beijing-Tianjin-Hebei region in 2010-2015, 2015-2020 and 2010-2020. The color, width and transfer direction of each transfer line in the chord diagram represent the corresponding land type, transfer area and the conversion relationship between land types respectively( e. g. , in the third picture, the green lines turn to yellow and purple areas, that is, the areas of grassland turning to cultivated land and woodland are 103200.26 ha and 191218.61 ha respectively.)
Point 4: Figure 6. The labeling of the x and y axes is cut off
Response 4: Figure 6 has been displayed completely.
Point 5: Figure 8. Enlarge it
Response 5: Figure 8 has been enlarged to clearly show the labels.

Reviewer 2 Report
Very interesting paper dealing with the dynamic of land use changes due to cities expansion. It is based on GIS technologies and the appropriate models based on a number of parameters. But the ecological subjects are multiparametrical and during the construction of the models one or more parameters are missing. These parameters, perhaps, are the most important. You have already mentioned some weaknesses in your research and I agree with them. I would like to add something which is the local and national policy with the future plans and restrictions on the subjects of cities expansion and nature protection.
In your conclusions please add:
-The need for systematic monitoring of urban, periurban, natural, seminatural and artificial Ecosystems and especially the priority habitats and the endangered plant and fauna species, using the new technologies supported from the classic scientific sivicultural and ecological methods.
-The need for the creation of sustainable cities with the appropriate green infrastructure and especially a minimum of good quality green spaces ranging to 8-10 square meters per inhabitant.
-The need for creation of mixed forests, using the appropriate indigenous and endemic forest species following the principles of Silviculture.
The research subject is very broad and the enrichment of bibliography is necessary (worldwide research) for finding paradigms of good practices.

Response 1: Suggestions have been put into discussion, with the first two measures in lines 462-468 and the third one in lines 484-486.

Reviewer 3 Report
1) Consider writing the abstract fluently, without square brackets: [Objective] [Method] etc. (unless required by the journal).
2) In Figure 1, consider putting the text labels in another format so they can all be read well.
3) Try to use another expression than "It can be seen" (repeated many times).
4) Line 371 (beginning): space after the dot ("tat.With")
5) Line 486: Handan by 2030; Although

Point 1: Consider writing the abstract fluently, without square brackets: [Objective] [Method] etc. (unless required by the journal).
Response 1: In order to solve the problem of habitat fragmentation in Beijing-Tianjin-Hebei region and realize sustainable use of land, based on the remote sensing data from 2010 to 2020, this paper uses GIS and CA-Markov model to predict the land use structure in 2030, and uses Invest model to quantitatively analyze the changes of habitat quality in Beijing- Tianjin- Hebei region from 2010 to 2030. The results indicate that:
Point 2: In Figure 1, consider putting the text labels in another format so they can all be read well.
Response 2:
Point 3: Try to use another expression than "It can be seen" (repeated many times).
Response 3: Seven repeated words were found in the paper, and six were revised, namely, 179 lines, 183 lines, 338 lines, 358 lines, 362 lines and 404 lines.
Point 4: Line 371 (beginning): space after the dot ("tat.With")
Response 4: This error was found in line 391 and has been modified.
Point 5: Line 486: Handan by 2030; Although
Response 5: Duplicate words were found here and have been modified.
