Abstract:

This study is based on the data from 125 national desert (rocky desert) parks published by the National Forestry and Grassland Administration. The spatial differentiation characteristics and factors influencing the national desert (rocky desert) parks were detected using spatial analysis, geographic detector, and a geographically weighted regression. The results revealed the following: (1) The distribution of the national desert (rocky desert) parks is “more in the north and less in the south” and the construction sequence is “first in the north and then in the south”. (2) The nearest neighbor index of the national desert (rocky desert) parks is 0.537, showing significant agglomeration distribution characteristics, but the agglomeration degree and scale are significantly different. (3) The national desert (rocky desert) parks show a pattern of “sparse in the south and dense in the north and dual-core belt” in space, with substantial spatial differentiation characteristics. (4) Physical geographic factors have stronger explanatory power than human factors for spatial differentiation of the national desert (rocky desert) parks,and the interaction effect between the physical geographical factors and the human factors is significantly stronger than the interaction of their internal factors. (5) The effects of the six factors with the strongest explanatory power on the spatial differentiation of national desert (rocky desert) parks showed a trend of increasing positive effect and decreasing negative effect from southeast to northwest, and the northwestern region was the strongest influenced by natural geography and human factors.

Key words: spatial differentiation, geographic detector, geographically weighted regression, national desert (rocky desert) park
