摘要: 通过对不同高程(1158m、1270m、1341、1407),不同坡向(峁顶、阳坡、阴坡、阳沟坡、阴沟)情况下20个观测点的降雨量监测,经过分析研究表明:对于丘陵沟壑区的山地降雨,在不考虑坡向影响的情况下,降雨量基本随着高程变化规律为,先增加后减少;在同一高程,不同坡向情况下降雨量的分布规律为:阴沟坡>阴坡>峁顶>阳沟坡>阳坡,即阴坡(背风坡)>阳坡(迎风坡);不同高程情况下亦是如此。

Abstract: Based on the rainfall observation with different elevation(1158m、1270m、1341m、1407m),and different slop directions(peak、positive slop、shade slop、positive chimb slop、shade chimb slop) about 20 observation station. The research results showed that without the influence of slop direction the rainfall increase first and reduce then, in the same elevation the rainfall distributing rule with different slop directions is shade chimb slop>shade slop>peak>positive chimb slop>positive slop,and the conditions of different elevation is the same.
