GIS支持下小流域农林复合经营的侵蚀控制模拟 --以冀西北青边口河小流域为例

open access: yesShuitu Baochi Xuebao, 2001
根据张家口郭家梁试验场的小区资料,建立了小流域侵蚀产沙模型以及植物篱侵蚀控制模型 ;并在GIS的支持下,从小流域数字高程模型(DEM)中提取基于地块间水沙汇流网络,生成基于地块的水沙运移网络图,并将地块间的水沙汇流过程引入小流域侵蚀产沙的模拟中,实现了侵蚀产沙模型与地理信息系统(GIS)的深层次耦合,模拟出坡面水沙在小流域的空间运动过程.1995~1999年青边口河小流域模拟结果表明,坡耕地、荒坡地、低覆盖的天然草地平均侵蚀模数最大,是侵蚀控制的重点土地利用类型.在坡耕地、荒坡地 ...
