Study on the environmental system planning method for watershed under incomplete information
不完备信息条件下流域环境系统规划方法研究

This study developed a new environmental system planning method for watershed. The method integrated the IFMOP(Inexact Fuzzy Multi\|objective Programming) model and SD(System Dynamics) model into a holistic system.It possesses several important characteristics as follows: by giving the incomplete information condition fully consideration, the IFMOP can communicate the uncertain information into the process of model formulation and solution, so that some inexact solutions can be achieved; varied practicable planning schemes can be generated by intepreting the solutions within their solution intervals; the environmental and economic consequence can be successfully predicted by inputting the solutions of IFMOP into the SD model, this will be benefitable to the decision makers because the result of the SD model can provide them with many useful information for justifing and modifying the programme. So, by integrating the two models, the newly proposed method can effectively help the decision makers generating planning schemes and evaluating the environmental and economic consequences of each programme. The method has been successfully applied in the environmental planning for the Lake Erhai Basin, Yunnan Province.
