Study on the simulation model of water environment pollution in plain lake basin

For reasons of temporal and spatial changes and strong randomness etc, the quantitative simulation for water environment pollution in plain lake basin is a much difficult work all the time. Simulation model makers are required to comprehensively master, as well as synthesize many methods or techniques to describe the natural and social complex systems. In this paper, Lake Chao was taken for example, a system dynamics(SD)-based method was proposed to simulate the cause, distribution and movement of the water environment pollution. Results show that, system dynamics, based on the info-feedback structure and combination of qualitative analysis and quantitative calculation, have the ability to simulate water environment pollution in plain lake basin. It can provide an efficient policy-experiment platform for department appointed to manage the Lake Chao basin.
