摘　　要：以黄河中游河龙区间南片区域为例，通过对黄河中游地区各地水保试验站不同系列径流场（区）的径流测验资料的分析论证，在综合考虑区域降雨、自然地理、水土流失类型区等因子的前提下，提出了建立由小区到大区以数理统计为基础的水土保持坡面措施减洪指标体系的研究方法。可改进以往经验性指标的人为指定性，对以成因法为主的流域水沙分析研究中减洪指标的确定，提供了系统程式化的可能途径。To analyse the rnnoff data of different series of runoff plat at the experimental stationsof middle Yellow River region such as south area of Yellow River from Hekou to Longinen.Amodel for setting up reducing flood index system of soil and water conservation arrangments onslopes from some area to a certain region has been given based on statistical analyses.Consideringsynthetically rainfall,physical geography and soil and water loss at a pthicular area,the previousexperimental decision on purpose is improved,and the way for determining the reducing floodindex synthetically and formally is given as a useful methed in analysing the formation cause offloods and sediments.
