摘要
采用数学统计方法，将长江上游约１００万ｋｍ￣２地区划分为９５个样本区（Ｓ＿９５）。按照危险度高、中、低三个等级，区划出高危险度区（ＤＵＳ＿ｉｊ）约２５万ｋｍ￣２；中危险度区（ＤＭＳ＿ｉｊ）约３２万ｋｍ￣２；低危险度区（ＤＬＳ＿ｉｊ）约３８万ｋｍ￣２。并对三种危险度区域内的滑坡危害作了概述。
The area of 100 ×10￣5km￣2 are divided into 95 samples S_95 by mathematical statistic methodon the Upper Reaches of the Yangtze River. According to three grade system, the upper danger de-gree area DUS_ij of 25× 105km￣2,the middle danger deree area DMS_ij of 32× 10￣5km￣2 and the low dangerdegree area DLS_ij of 38 × 10￣5km￣2 is determined.At last,the landslides danger are introduced simplelyin three different areas.
