Other AbstractTo achieve comprehensive control model in small watersheds, in the hilly area of Sichuan Province, 212 small watersheds belonging to 37 counties managed by 9 cites were comprehensively treated using integrated farming, ecological and engineering measures for 5 years. Results showed that: 1) As against the original status, the area of farmland with slope over 25° decreased 49.28 times, per capita basic farmland area increased 0.21 times, gross agricultural output value and per capita net income improved by 37.91% and 25.92% respectively, the amount of sediment interception improved 5.41 times, and the ability of runoff interception improved 2.19 times. 2) The increase amplitude of forestry total output value reached to 138.13% brought by ecological measures. Water conservancy and soil and water conservation projects could improve the water use efficiency and protective mechanism of farmlands. After 5 years treatment, the amount of sediment interception improved nearly 5 times, while the ability of runoff interception improved nearly 3 times. 3)The social benefits got remarkable results. Environmental population carrying capacity increased by 5.97% by using grain consumption as the standard, while increased by 37.97% by using value consumption as standard. It indicated that the comprehensive treatment on these small watersheds has got fruitful outcome supported and cooperated by local farmers. Farming measures could bring significant economic efficient, so it should be the starting point of watershed comprehensive management.
