Analysis of Landscape Pattern on Soil Erosion in DongZhen Reservoir with GIS
Based on the data sources of remote sensing SPOT-5 images and soil erosion intensity map of Dongzhen reservoir, this paper takes land-use landscape as the research subject, and uses GIS information management and spatial data analysis and processing functions as methods, extracts information of the landscape pattem characteristics, chooses indexes of analysis for landscape pattern, then research quantitatively; the aim is to find out some laws, discussing the relationship between landscape pattem and soil erosion process, and the influence of human activities to landscape pattem and ecological process as well; the study shows: reservoir landscape types and ecosystem distributed unevenly; with the increase of erosion intensity, diversity index and uniformity both reduces; the high degree of crushing of Dongzhen reservoir garden plot and farmland landscape is main cause of soil erosion.
