| Abstract: | The benefits of the projects of rainfall collecting and water keeping in hilly slopeland of Sichuan Basin are evaluated through the examples of Fuxing town, Zhongjiang county. On the coverage project it can hold and keep the runoff of 480m 3/hm 2, which makes up account of 22 7 percent of all. It can decrease the soil loss of 3593kg/hm 2, and increase annually grain output of 2373kg/hm 2 on the average, with the amplitude of 49 percent. It also can provide people and animals with the water source. Therefore the benefits of the projects are notable for both holding floods and keeping soil in order to prevent the draught. |
