陕西省黄河流域泥沙流失变化分析

本文以陕西省黄河流域为研究对象,运用实测水文资料,根据水沙平衡原理,分析计算了陕西省黄河流域出、入境和自产径流量、输沙量。通过对自产水沙量的变化分析,寻找本省黄河流域水沙变化的特点和主要影响因素。阐述了泥沙流失的分布区域,并以泥沙流失的重点区域无定河流域为典型进行深入分析,从而进一步为陕西省水土保持、水资源保护和生态建设提供决策依据。

Analysis of the Variaty of the Sediment Losses in the Yellow River Basin in Shanxi Province

With the Yellow River Basin in Shanxi Province as the research object, this paper analyzes and calculates the in-and-out and self-producing runoff and sediment discharge, with the observed hydrologic data being used, based on the principle of water and sediment balance. It makes analysis of the the runoff and sediment discharge to look for the characteristics of the variety of the runoff and sediment discharge and the influence factors in the Yellow River Basin in Shanxi Province. This paper also describes the distributed areas of the sediment losses, and makes an analysis with the Wudinghe River Basin as the study case.
