河北山区流域土地利用变化的水文效应及对策研究

On the Hydrological Effect of LUCC and Management Strategies in Hebei Mountainous Region

基于1987年和2000年遥感影像数据,选取生态环境脆弱的河北太行山区的子牙河和大清河流域为研究对象,对比分析河北太行山区子牙河流域和大清河流域土地利用/覆被空间格局变化,再运用SWAT水文模型模拟其土地利用/覆被变化(LUCC)的水文效应,从而有针对性地提出山区流域应优化土地利用结构,切实保护林草资源,增强水资源涵养能力的建议.

In this paper, based on remote-sensing image data in 1987 and 2000, it＇s selecte a fragile ecological environment of Ziya River and Daqing River in Hebei Taihang mountain as the research object. Firstly, it＇s analyze land use / land cover spatial pattern changes in the Ziya River and Daqing River in Hebei Taihang mountain, then use SWAT hydrological model to imitate the hydrological effect of LUCC in the two mountain watersheds. Secondly, it is proposed that mountain basin should be made to optimize land-use structure, protect of forest resources effectively, and enhance the capacity of water resources conserv- ation.
