摘　　要：通过对渭河流域１２条主要支流的产流、产沙规律探索和对降雨、径流、输沙资料的统计分析，应用数理统计原理分别建立了各支流的降雨—径流和降雨—产沙经验公式，并用该公式计算了各支流７０～８０年代水土保持措施的减水减沙效益，取得了比较可靠的初步结果。从而，为流域治理规划、合理开发利用水土资源提供了科学依据。Byapplication of statistic theory,we provide experiment formulas of rainfall-runoff andrainfall-sediment for different branches based on the study of regulation on runoff and sediment dis-charge of main twelve branches located in Weihe watershed and statistic analyses of rainfall,runoffand sediment data. We apply the formulas to calculation of the benefits of decreasing runoff and sed-iment of control measures of soil and water conservation under each branch from 1970s to 1980s,areliable preliminary result has been obtained.It provide scientific basis for control planning,reason-able development and utilization soil and water resources,
