黄土高原城市产流与降雨关系的研究

Study on the Relationship Between Runoff and Rainfall of City in Loess Plateau

基于71次有效降雨的观测数据,通过分析城市硬化部分产流及集雨效率与降雨的关系,得到了单位面积集流场的产流量与降雨量的关系方程以及实际集雨效率与降雨量的关系方程,为今后的集雨工程设计提供了理论依据。

Based on the observed data of 71 times effective rainfall, by analyzing the relationship between the city hardened surface runoff, rainwater collection efficiency and rainfall, the paper obtained the relation equation between runoff yield and rainfall in per unit area of rainwater catching field and between actual efficiency of rain collecting and rainfall which can provide the theoretical basis for the design of rainfall collection engineering in future.
