渭北高原小流域水土流失综合治理工程体系配置及设计规格标准

The Study on Engineering System Match and Designed Standards of Small Watershed Comprehension Control in Weibei Loess Plateau

本文根据“七五”、“八五”期间在渭北淳化泥河沟流域进行的综合治理试验研究和对该地区有关调查资料分析，并通过对渭北地区彬县、合阳等９县２０年的年日最大降雨量频率分析计算，从地貌特征和水土流失现状出发，分析探讨了该区小流域水土流失综合治理工程体系配置的一般规律及设计规格标准。

Analysed and approached general regularity of engineering system match and designed standards in small watershed comprehension control on the basis of geomorphological characteristics and existing of soil and water loss, Above mentioned questions are obtained by test and study data, from comprehension cantrol of Nihegou watershed, Chun Hua county, maximum. annal and day precipitation frequency calculated in 20 years in Binxan、Heyang and other 7 county of Weibei Loess Plateau.
