The hilly area in the middle of Sichuan covers 121 000km2,soil and water loss area is 63. 7 percent’ According to the Suining urban district research for comprehensive harnessment measures to the five typical small watersheds and its benefits, five different kinds of experimental plots have been tested. We have analysed and evaluated them by using quantitative and qualitative analysis,calculation and evaluation, divided calculation and special combination. The results were very notable. By practice, it’s proved that comprehensive harness of the small watersheds is a useful way to mitigate inundation and drought, exploit soil and water resources rationally, help the peasants be lifted out of poverty and make them richer, lt’s also a successful road to develop agricultural economy in hilly area of the middle of Sichuan.
