ZHOU Zhong-fa. Analysis of Relation of Rock Desertification to Landform and Gradient in Karst Region—A Case Study of Qingzhen City of Guizhou Province[J]. Bulletin of Soiland Water Conservation, 2006, 25(5): 1-3.DOI:
Rocky desertification in the karst region is related to stratum and lithology
incising of river
soil ero- sion
gradient and human activities
etc.Effects of gradient on rocky desertification in the karst region was analyzed by taking Qingzhen City
Guizhou Province as an example.GIS technology was used for the analysis of spatial distribution of deserts and landform gradient based on correlation data of rocky desertification in Qingzhen City.It is found that the largest area and the greatest extent of rocky desertification are observed in the places with the highest gradient and the most intense human activities.The reverse case can be found in the places with smaller gradient and fewer human activities.Therefore
it is thought that the extent and distribution of rocky desertification are related to landform and gradient in the karst region.
