摘要
通过对甘肃环江流域降雨产流产沙特性的分析，发现流域产流产沙量与流域最大２４ｈ平均降雨量关系最为密切，由此建立了一种简单实用的降雨产流产沙数学模型，并用之计算了流域１９７０～１９８９年综合治理的蓄水减沙效益；
The analysis of the characteristics of runoff and sediment yield in the Huanjiang basin, Gansu province, Shows that the relationship between runoff and sediment yield and maximum 24 hours average precipitation was the close, a simple and practical mathematical models of runoff and sediment yield were set up. The benefits of water reception and sediment reduction after comprehensive control in the basin from 1970 to 1989 were calculated with the models, and the change trend of runoff and sediment and the utilization of water resources in the basin in 1990’s were preliminary analysed.
