摘要
本文选取图们江干流3个控制水文站的年含沙量资料,运用Mann-Kendall突变检验法进行统计分析,并对分析结果综合对比分析,得出图们江干流水土流失严重,特别是开山屯水文站以上断面,含沙量增加趋势明显,下垫面改变剧烈,人类活动已严重影响到当地气候变化,变得干旱少雨。通过本文对含沙量的趋势分析,以期为图们江流域水资源的科学管理与合理利用提供参考依据。
In this paper, the authors select the annual sand contents data of 3 hydrologic stations in Tumen River main stream, using Mann-Kendall mutation test method, contrast comprehensively analysis results. Obtain the results that water soil erosion of Tumen River main stream is severe, especially the section above Kaishantun hydrological station, sediment concentration increased obviously, the underlying surface change violently, human activities have seriously affected the local climate. Through the analysis of sand contents trend, the authors expect to provide reference for scientific management and the rational utilization of water resources in Tumen River basin.
