摘　　要：应用系统动力学理论研究建立了长城沿线农牧交错带生态环境恢复与重建SD模型 ,并应用该模型对该区强化治理型、协调发展型和传统经营型 3种典型治理模式进行仿真研究结果表明 ,强化治理模式为农牧交错带生态环境治理最佳模式 ,可使农林牧协调持续发展 ,土壤侵蚀量减少 76 .1% ,生态环境趋向良性循环。The rebuilding of SD model and resuming of the ec o-environment in the agriculture and animal husbandry interlock zone along the Great Wall were establ ished by a system dynamic theory,and a simulating study for three typical manage ment patterns,a intensified management,steady development and traditional manage ment,in the region was made by the SD model.The results show that the intensifie d management pattern is the best approach to harness the eco-e nvironment in the region,it can balance the development of agriculture,forestry and animal husband ry,reduce the soil erosion by 76.1%,return a good circle of eco-environment in the region.
