| 摘 要： | 通过对浑河流域降雨，产流，产沙特性分析和降雨，径流，输沙资料统计，采用成因分析法建立了适合该流域的降雨－径流和降雨－产流经验关系。用水文法和水保法对流域８０年代减水，减沙量计算的结果表明，所减水量中，降雨和流域治理的作用分别占４１．５％和５８．５％；所减沙量中，降雨和流域治理的作用分别占２１．１％和７８．９％。

| Abstract: | Through the analysis on the characteristics of precipitation,yield and sediment production and thestatistics of precipitation,runoff and sediment delivery data of the Hun River basin,it sets up empirical rela-tions of precipitation-runoff and precipitation-yield which suit the basin by using genetic analysis method.Itis shown by the result of calculating the volume of water and sediment reduction of the basin in 1980s byusing hydrologic method and conservation method that in the reduced water volume,the functions of precip- itation and basin management make up 41.5% and 58.5% respectively and;in the reduced sediment vol-ume,the functions of precipitation and basin management occupy 21.1% and 78.9% respectively. |
