| 摘 要： | 采用Mann-Kendall法对浊漳河侯壁站、清漳河匡门口站1956~2007年的年径流系列进行趋势和突变检验,揭示了两站年径流量呈明显衰减的趋势,并分析了导致径流量衰减的原因,考虑气候变化和人类活动对径流情势的影响,预测了丰、平、枯水年的径流量,为漳河水资源的公平合理分配提供依据。

| Abstract: | Based on the annual discharge data of Houbi hydrological station in Zhuozhang River and Kuangmenkou hydrological station in Qingzhang River during 1956-2007,the trends and the abruptions of runoff were detected using the nonparametric Mann-Kendall test.It was found that the series of annual runoff of two stations have significantly decreased during the period.The reasons of decrease in runoff were analyzed.Considering the impacts of climate change and human activities on runoff,the annual runoff was predict... |
