摘　　要：提出了社会、经济、资源与环境之间的合理结构以及人为有效的调控措施是区域可持续发展的基本驱动力 .以大兴县为例 ,从限制性因素水土资源合理利用出发 ,利用系统动力学方法构建了亚湿润干旱区沿河沙地可持续发展的动态仿真模型 ,并对该模型做了模拟调试和多方案的仿真实验 .The main driving forces for regional sustainable development focus on the reasonable structure and development of each subsystem and their effective adjustment. On the basis of studying the completed system by taking Daxing county as case study and making the reasonable use of water and land resources,then, using the method of dynamics system,the dynamical imitation model for the sustainable development of the River-sandy Land System in Sub-humid Area is presented.Researches on the problems about simulation and adjustment are also conducted on the case of Daxing county and a foundation and direction to the development of the River-sandy Land System in Sub-humid Area is provided.
