【摘要】 通过数字化地形图构建大山包羊窝河流域数字高程模型,生成羊窝河流域DEM,利用DEM提取流域水系、子流域、汇流方向及汇流量.结合河道简化,用GIS模拟出羊窝河流域地表径流及筑坝后黑颈鹤适宜栖息生境动态变化.进一步研究羊窝河流域筑坝地点选择、筑坝高度与汇水量关系,为羊窝河流域湿地水文恢复工程建设提供依据.更多还原

【Abstract】 The Digital Elevation Model(DEM) of Yangwo river watershed is composed through digitizing map.The streams,sub-watershed,flow direction and flow amount were imitated were extracted using DEM.The surface runoff and change of black-necked crane habitat of Yangwo river watershed were imitated by GIS.More research is needed on selection of dam site along Yangwo river watershed,the relationship between dam height and water-collecting amount.更多还原
