水文下垫面对河川径流的影响分析

Analysis on influence of the hydrologic lower bedding course upon the river runoff

水文下垫面是一个多种因素的综合体,影响径流特征的下垫面因素主要有地质条件、地貌、植被覆盖等,通过对山西省不同水文下垫面的降雨径流分析,得出了水文下垫面与河川径流的关系,以及水文下垫面对河川径流的影响特征。

The hydrologic lower bedding course is a comprehensive mass of multi-factors. The factors of lower bedding course that influence the features of runoff includes geological condition, geography and vegetation. Through the analysis of rainfall runoff on different hydrologic lower bedding courses in Shanxi Province, this paper reflects the relation between the hydrologic lower bedding courses and the river runoff.
