| 摘 要： | 对黄土高原沟壑区长武王东沟流域土地利用变化对产水量的研究结果表明，王东沟流域土地利用变化主要特点是农田、草地面积所占比重减少，而林果面积迅速增加。同样降雨类型1996年和2010年流域下垫面的产水量分别比1986年少产水5747m^3及5914m^3。产水量的减少使该流域汇入河流的水量减少，土壤蓄水量增加，有利于流域生态环境的持续发展。 |

| Abstract: | 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. |
| Keywords: | Wangdonggou small watershed Land use change Water yield |
