Influencing factors of watershed ecological compensation efficiency based on system dynamics

为剖析流域生态补偿机制水平影响因素,提高流域生态补偿效率,通过文献分析,总结归纳了影响流域生态补偿效率的18个影响因素,基于系统动力学模型对影响因素作用机理进行了深入研究。利用VENSIM软件对各影响因素的投入变动进行了敏感性仿真分析,得到各影响因素对于系统整体水平的影响力度,并根据影响力度将影响因素划分为关键、重要及次要3个等级,针对3个等级的影响因素分别提出了提升流域生态补偿效率的对策与建议。

In order to analyze the factors affecting the level of the ecological compensation mechanism and improve the efficiency of ecological compensation in the river basin,on the basis of document sorting and analysis,the 18 influencing factors that affect the ecological compensation efficiency in the river basin are summarized and analyzed based on the system dynamics model.The research uses VENSIM software to conduct model simulation analysis,conduct sensitivity analysis on the input changes of each influencing factor,and obtain the influence of each factor on the overall level of the system.The factors are divided into key,important and secondary levels according to the impact strength,and the countermeasures and suggestions for the establishment of the compensation mechanism are put forward respectively.
