Impact of land use change on the water yield of typical small watershed in gully region at loess plateau-A case study from Wangdonggou watershed in Changwu,Shaanxi Province
黄土高原沟壑区典型小流域土地利用变化对产水量的影响——以陕西省长武王东沟流域为例

The impact of land use change on the water yield of Wangdonggou watershed of gully region at loess plateau in Changwu was studied. The results show that the characteristics of land use change are mainly reflected in the decrease of farmland and pasture area and the increase of forestland and orchard area. Compared to 1986, the runoff decreased by 5747m^3 in 1996 when the precipitation in 1988 was used, and it will decrease by 5914m^3 in 2010, which makes the collected water reduce, the storage of soil water increase and the eco-environment continuously develop.
