Karst rocky desertification is a kind of land degradation phenomenon which harmful and difficult to control. Rocky monitoring based on remote sensing technology an effective method. In this paper, Chongzuo Qianxinan Prefecture in Guangxi Province are used as experimental areas, Landsat8 TM / OLI images ASTER GDEM elevation data sources, three factors vegetation coverage, bedrock exposure slope characteristic variables. The decision tree constructed extract the information study area, grade divided according results.

Territory space is an ecological resource carrier and place for human development. Human activities systems are the basis of product supply. Promoting territories’ spatial protection governance by improving supply products very important. In this study, we established capacity evaluation index system involving three types products, i.e., environmental material cultural products. For case Beijing–Tianjin–Hebei region, comprehensively used principal component analysis, equivalent factor method, entropy method to evaluate from 2011 2021. Then, analyzed spatio-temporal pattern, combining natural breakpoint quantile classification methods, obstacle factors using degree model The results show that different in each city closely related their endowment. exhibited upward trend, with highest being relatively smaller than supply, while largest growth rate was varied across cities over time displayed noticeable differentiation. main included eco-land, eco-tourism, eco-leisure, park green space, fishery although there were variations among cities. Finally, based on level, spatial-temporal proposed strategies territory perspectives integrated elements, structural regulation, systematic governance. reflected functional heterogeneity which can provide planning guidance sustainable
