摘要
通过三川河流域30多年的降雨、流量和泥沙等水文观测资料的分析,认为该流域的泥沙主要来源于中游地区,同时认识到在1980年以来由于地方工业的发展,特别是在煤矿资源的大量开发利用过程中,将弃杂置入河道不仅影响洪水的正常演进,也降低了水质,影响着沿河两岸工农业生产的正常发展和人民的正常生活。
By analyzing hydrology observation data such as precipitation, run-off and sediment of the Sanchuan river over the past 30 years, the article draws the conclusion that the sediment of the valley mainly comes from the middle reaches of the Yellow river.At the same time it realizes the fact that because of the development of the local industry since the 1980's, especially with the excessive exploitation of coal mine resources,the trash that people dump into the channel will not only affect the flood's normal course and depress water quality, but will also affect people's normal lives and the normal development of agriculture and industry along the river.
