Study on the soil thickness factor of plant growth in karst mountains——Take the Guizhou Xiangbao Mountain as an example

Guizhou is in a typical karst area,which has more than 70% of karst distribution.Various disasters frequently occur,and ecological deterioration,desertification phenomenon can be seen everywhere.In the desertification governance,the restoration of vegetation,soil and water conservation managements occupy an important position.So the plant growth thickness of the soil conditions in desertification and the mountains is a prerequisite.In this paper,the thickness of the vegetation soil factors of Guizhou Xiangbao Mountain is studied and the statistical relationship between the vegetation and soil thickness is obtained.Then the soil thickness distribution from the top to the foot of the hill is discussed
