郑州市土地承载力系统动力学研究

在对郑州市农业系统进行辨识与诊断的基础上，描述了土地承载力系统各影响因素间的相互制约，相互促进的反馈关系，揭示了土地承载力系统的运行机制和控制机制，建立了郑州市土地承载力系统动力学模型，通过不同的策略方案，模拟了各方案下土地承载力系统的动态趋势，对系统动态仿真结果进行了分析，并提出了缓解郑州市人地矛盾的若干对策。

System Dynamics for Zhengzhou Land Resource Bearing Capacity

Based on the diagnosis of Zhengzhou agricultural system,feedback relation of the elements in the land resource bearing capacity system is analysed,the operation mechanism and controlling mechanism of the system are revealed,the system dynamic model of Zhengzhou land resource bearing capacity is established,the dynamic tendenies in different programmes are simulated,the results from the model are analysed,and countermeasures and ways for mitigating the contradiction between population and land resource are suggested.
