湿地蓄水量动态SD仿真研究——以三江平原沼泽湿地为例

System Dynamics (SD) Simulation on the Trends of Mire Water——A Case Study on Mire Wetland in Sanjiang Plain

在沼泽湿地水循环系统分析基础上 ,根据系统动力学方法和原理 ,探讨湿地蓄水量动态仿真的方法、步骤和过程 ;以三江平原湿地生态实验站沼泽湿地为例 ,通过系统分析、函数建立、程序编写等过程建立了沼泽湿地蓄水量动态仿真模型 ,对模型反复检验和调试 ,直到获得较好的仿真效果 ;通过 1997、1998、1999连续三年湿地水位变化实测与仿真结果的对比显示 ,仿真效果较好。

For solving some ecological problems and making policy decisions, simulation of seasonal trends of water in mires is an effective tool . According to the method and theory of SD and based on the systemic analysis of mires' water circulation, the steps and processes of the simulation are discussed. Taking the mire in Sanjiang Plain Wetland Ecological Experiment Station of Chinese Academy of Sciences as an example, the simulation model of the seasonal trends of water is established through system analysis, data collection, and program compilation. After correction, it is found that the simulation result is acceptable through the comparison between the results of simulated water depths and measured water depths in the mire in 1997,1998,and 1999.
