Using successive regression and GIS technique, the regression equations of the precipitation and the topographical data in the upper-middle reaches of Yangtze River are established based on the 10 years daily、 mensal and annual precipitation of 613 meteorological stations, from 1992 to 2001. The topographical data include the elevation, aspect and slope form DEM of 4km resolution.

本文首先利用逐步回归和地理信息技术，最新的长江中上游613个气象站，1992～2001年10年降水资料，建立了日、月、年降水与4km分辨率的DEM高程、坡向、坡度等地形数据的回归方程，将降水量中地形影响部分分离出来。
