渭河定西段水文水资源状况分析

Research on Investigation of Hydrology and Water Resource Situation of Dingxi Section of Weihe River

根据渭河定西段流域内的径流观测资料,分析了渭河水情变化趋势。同时,通过分析渭河枯水期径流变差倾向率(LRR);径流年际交叉倾向率(VAR)两个指标,对渭河近年来水文水资源准则层(HD)进行评估,得出渭河定西段水文水资源的健康状况,并对存在的问题进行分析。

Based on the runoff observation data of Dingxi section of Weihe River, it analyzes the water situation change trend of Weihe River. At the same time, by analyzing the two indexes of LRR and AVR in the dry season of Weihe River, it evaluates the hydrological and water resources HD of Weihe River in recent years. It also gets the health status of the hydrological and water resources in the Dingxi Section of Weihe River, and analyzes the existing problems.
