摘要： 本文根据降水随海拔高度变化的不同参数，对山区地形方位进行分区，在分区的基础上，建立山区雨量推算方程，推算平均相对误差为2.03%,然后利用小网格点法，推算华北山区年降水量分布和最大降水高度。

关键词: 华北山区, 年降水量, 推算模式

Abstract: According to the variation of different parameters of rainfall with height,14 sub-regions in the North China mountainous regions are divided. A study on relations between variation of rainfall and geographical parameters is made. A regression equation is expressed as follows:Pi=a0i+a(1i)ψ+a2iλ +a3ih Where Pi is rainfall calculated,a0iis a constant,a(1i),+a2i,a3i are the partial correlation coefficients,ψis latitude,λis longitude, h is the height above sea level.The average error for calculation is 2. 03% and the maximum average error is 4. 61%.Making a calculation for every 10’ of latitude and longitude and substituting h for λ and ψ in the equation above,we can calculate the rainfall and the maximum rainfall height in a specified sub-region.

Key words: mountainous region, annual rainfall, calculation equation
