基于突变级数的中国“城市矿产”产业生态系统评价研究

Evaluation of the ecosystem of urban mines industry based on catastrophe progression method

根据中国城市矿产产业链组成和相互关系,将其生态系统分为"管理、供应、回收、资源化、市场化"五元子系统。采用生态位和突变级数理论,从基于"态、势、能"的生态位角度,建立了包含共生模式、共生环境、共生水平的产业生态系统的综合评价指标。运用突变级数法的控制变量与状态变量来描述关键因素与指标的质变、突变过程,从而对城市矿产生态系统稳定性进行综合评价。最后,将突变级数法运用到湖南汨罗城市矿产示范基地进行实证分析,所得结论和实际产业状态相吻合。

This paper analyzed the China urban mines industry ecological chain,its ecosystems are divided into "management,supply,recycling,resource and market" five subsystems.Based on niche theory and Catastrophe Progression theory,an evaluation index was established from "state,potential and energy" ecological perspective.By using the control variables and state variables of Catastrophe Progression Method to describe the key factors and indexes changes,a comprehensive evaluation on the stability of industrial symbiosis ecosystem is conducted.This method were utilized for evaluating Hunan Miluo urban mine industrial park ecosystem,which was proved feasible in practice and have high objectivity and reference value.
