摘要

应用传统的径流系数法与SCS-CN模型法预测了北京市门头沟西侧小流域雨水资源利用潜力

并对比了不同方法预测的雨水资源量及其时空分布规律。结果表明

径流系数法预测的丰水年(P=25%)、平水年(P=50%)、枯水年(P=75%)和多年平均年份地表雨水资源量分别为:2.84×10

1.98×10

1.22×10

和2.14×10

。模型法预测的丰水年、平水年、枯水年和多年平均地表雨水资源量分别为:3.21×10

2.16×10

1.31×10

和2.50×10

经验法预测值小于模型法。夏季的7月

地表的雨水资源利用潜力达到相应特征年份的最大值。

Abstract

The potential of rainwater resources utilization were calculated and compared using the empirical formula method and SCS-CN model method.The amount of surface rainwater resources through different methods were analyzed and contrasted monthly and seasonally to find time and spatial distribution of water resources.Result showed that the predicted amount of surface rainwater resources by the empirical formula method in wet years(P=25%)

flat water years
