城市生活垃圾的生产、收集、处理、处置过程涉及多个环节,是一个复杂系统。本研究使用系统动力学的方法对城市生活垃圾处理的整个流程进行梳理并建模,从经济、社会和环境的大视角出发,分析和解决城市生活垃圾问题,特别是对回收过程中的非正式就业问题进行研究。模型把城市生活垃圾回收分为三个环节,其中前两个环节存在大量的非正式就业,这个问题急需重视,政府需要逐步有序地取代或整改不正规的垃圾回收环节,改善垃圾回收从业人员工作条件。%The municipal solid waste (MSW) is a complex system that included four aspects:generation, collection, treatment and disposal. This paper builded a system dynamics model to simulate the system of municipal solid waste from the perspective of economy, society and environment. The model focused on the informal employment in the process of MSW sorting collection. The MSW recycling includes three steps, and there are large numbers of informal employment in the first two steps. According to the results, the government should pay more attention to the MSW problem, gradually and orderly to replace MSW collection or rectification of informal steps, improve the working conditions of employees in MSW collection.
