摘要
选用1961年--2010年50年的水文资料，分析了唐山市山区河流泥沙变化的趋势，通过年代间比较分析和年径流输沙双累积曲线方法，分析出泥沙减少的主要因素，结合水利和水保工程印证了下垫面和泥沙减少的相关性，得出了泥沙加速减少的结论。
Through the hydrological data of 50 years from1961 to 2010,this paper has analyzed the river sediment change trend in the mountainous areas of Tangshan City. By comparative analysis and annual runoff sediment transporting double mass curve method,the main cause of the decrease of the sediment discharge has been pointed out. The results from water and water ＆ soil conservation projects have showed corroborative correlation between underlying surface and decrease of sediment, and sediment decrease becoming speed up.
