摘要
该文以黄河中游多沙粗沙区典型支流为例,对80年代来沙减少的原因进行了分析。笔者认为降雨量减少和降雨强度减小是80年代泥沙减少的主因,其对减沙的影响程度约为70%;而流域综合治理影响程度约占总减沙量的30%。
Taking the typical tributaries in the sediment-rich area with more coarse ones inthe middle reaches of the Yellow River as an example, this paper analysed the causeof reduction of incoming sediments in the 1980s. The authors hold that the reductionof rainfall and intensity of rainfall was the main cause of sediment reduction in the1980s, whose effects upon sediment reduction were about 70%, while the effects of thecomprehensive control over the watershed upon the degree of sediment reduction ac-counted for 30% of total sediment reduction.
