土地利用变化对潘家口水库控制流域径流影响
Impacts of land use change on runoff in Panjiakou Reservoir watershed
摘要
Abstract
Taking the Panjiakou Reservoir watershed as study area,this paper analyzed the spatiotemporal variation of four land use data in 1970、1980、1995 and 2010,and evaluated the impacts of land use change on runoff and spatial distribution of hydrological components combined with the SWAT (Soil and Water Assessment Tool) model.The results show that the spatiotemporal variation of land use types is different which major included water reduction,the increase of forest and urban area expansion.Due to the transition from agricultural land and pasture to forest,the mean annual runoff decreased by 6.36％ in Luanhe,Yixunhe,Wuliehe and Laoniuhe sub-watersheds under 2010 land use scenarios.Land use change had little impact on runoff.Constructions of check dams and the increase in social water use were main factors which lead to annual runoff decrease.关键词
