基于嵌入式系统动力学的人水系统模拟及应用

Human-water system modeling based on embedded system dynamics and its application

基于人水系统概念和嵌入式系统动力学(ESD)方法,以一个相对独立的城市区为例,介绍人水系统模拟的ESD模型,说明ESD模型的优越性。通过ESD模型的模拟计算,分析实例区人水系统演变的主要影响因素以及调控方向和措施。模拟结果表明,该城市区总用水量在各年远未达到水资源可利用量,而水质控制目标已经达到临界状态;其发展的瓶颈是污水处理能力偏低,可以通过建设污水处理厂,增加污水处理能力,以提高该区的发展规模。

With a relatively independent urban area as an example, the embedded system dynamic（ESD） model for human-water system modeling was introduced based on the concept of human-water system and ESD method, and the advantages of ESD model were illuminated. Based on the numerical calculation, the main influencing factors on the development of human-water system and the regulation and control measures in the studied area were analyzed. The result shows that the total volume of water utilization of each year is far lower than the available volume of water resoources; however, the water quality control goal has reached the critical value. It is also concluded that the choke point to the development of this area is the relatively low capacity for sewage treatment, and that the construction of sewage treatment plants to improve the sewage treatment capacity is an effective measure to enhance the development scale of this area.
