Abstract:: This paper selected Qiaozidong watershed and Qiaozixi watershed in Gansu province as the research object to analyze their similarity, then the analysis method of watersheds comparative was determined. Influence of comprehensive control gully on water and sand in small watershed was studied through statistic and comparative analysis of the hydrological monitoring data of two watersheds (from 1986 to 2004). The results showed that: the situation of storage of water and sediment were changed by the measures of comprehensive control gully in small watershed, under the same precipitation condition, the process and change tendency of sediment concentration and flow rate in runoff were same in the comparative watersheds, but the indexes of the runoff and sediment production in watershed of governance were less than the corresponding indexes in watershed of not governance, and influence degree is correlated with the precipitation, the more precipitation is, the bigger its absolute value of decrement is, the smaller relative value of reduced is instead.
