系统动力学仿真方法在土地生态设计中的应用──以渭北高原沟壑区长武县为例

pplication of System Dynamics Simulation in the Land Ecological Design──Taking Changwu County of Weibei Plateau Gully Region as an Example

采用系统动力学仿真方法，建立了长武县土地资源—人口与社会经济—生态环境的系统仿真模型。依据仿真结果，提出了长武县本世纪末到２０２０年土地生态设计方案及其相应的实施策略和途径。

With the method of system dynamics,a simulation model about land resources,popu-lation and social economy,ecologic environment of Changwu county was establitshed.Accordingto the simulation results,the scheme and its actions of land ecologic design of Changwu from theend of this century to 2020 year were put forward.
