英文摘要	The Baisha river basin was extremely destroyed by the Wenchuan earthquake. This paper extracted the seismic-induced geological disasters data about 26km(2) within an area of 368.25km(2) by remote sensing interpretation and field investigation. This paper used arcgis to analysis these data, and divided the basin into several belts or zones base on slope, aspect, elevation and stratum lithology. The geo-hazard distribution analysis model was built to find some correlation between disaster distribution and geological factors such as terrain, stratum lithology and geomorphology by comparing among the parameters P-s, P-h, and P-c. The results show that most hazards occur where the slope between 300 degrees and 50 degrees, or aspect range is112.5 degrees to 202.5 degrees, and or the elevation between1140m and 3140m, the stratum lithology are the Huangshuihe group and The Middle Proterozoic common granite. At last the research zone is classified into four levels base on ground destroyed grade, and results show that the belts of most hazards located are not always the one destroyed most heavily.
