利用系统动力学擅长研究动态、非线性复杂系统的特点,将其应用于北湖水质改善分析,构建了系统动力学-水质耦合模型,可实现长时间序列的连续模拟和水环境管理的情景分析。文章定量分析了三产比例调整、城镇化率提高与污水集中处理等因素对流域纳污控制及水质改善的影响,推演出可协调经济发展-水环境保护-污水治理资金三方矛盾的合理方案,为类似小城镇的发展提供可借鉴的思路和方法。
The system dynamics is used to study the characteristics of dynamic and nonlinear complex systems. The system is applied to the analysis of water quality improvement in Beihu Lake. A system dynamics-water quality coupling model is constructed to simulate the long-term continuous flow and the scene analysis of water environment management. This paper quantitatively analyzes the impact of the adjustment of tertiary production ratio, the increase of urbanization rate and centralized wastewater treatment on the pollutant containment control and water quality improvement in the basin, and deduces a reasonable plan that can coordinate the economic development - water environment protection and sewage treatment funds. Provide similar ideas and methods for the development of similar small towns.
