Analyzing Degradation Ecological Landscape Pattern for the Karst Plateau on the Basis of GIS Technologies
The rock desertification is the results of the sharp conflicts between the human activities and soil,and the serious soil erosion.It is reflected as the phenomena of degradation ecological landscape.Through the pre-processing of 3D visualization GIS platform,the research is acquiring the landscape varieties based on the 3D modeling,and RS data sources,which is also based on the DEM models.It is to analyze the relevant landscape types of surface distribution of Tongjin village,Dafang County in the karst plateau of Guizhou Province,China.It is to reveal the current spatial distribution features and its development pattern of the degradation landscape varieties in the sample areas.It is concluded that the comparative outstanding feature of landscape degradation in the research sample area,which acquires to strengthen the ecological landscape recovery and comprehensive management for the sustainable development of resources and environment in the area.
