产业生态系统区域能值分析指标体系

针对当前产业生态系统评价指标体系缺乏和不完善的现状,整合区域经济学和能值理论、概念、综述研究方法和评价指标体系与思路,构建了产业生态系统区域能值分析指标体系。针对产业生态系统不仅具有闭路循环性,而且具有开放性、本土性和经济性的基本特征的评价需求,从资源消耗、内部循环、产出交换、废弃排放等方面,在原有能值评价指标的基础上补充构建了外资能值依赖率、能值出口率和能值内部反馈率等新指标。顺德市产业生态系统改革开放22 a发展动态的案例研究表明,新构建的产业生态系统区域能值指标,能够针对产业生态系统特点,进行有的放矢的分析研究,并具有多尺度整合研究的扩展弹性。

Emergy-Based Indices System for Regional Analysis of Industrial Ecosystem

A emergy-based indices system was established,to fill the evaluation need of industrial ecosystems,by integration emergy synthesis and regional economics methods.Based on the fundamental characteristic of industrial ecosystem,not only roundput,but also opening,locality and economy,three new emergy-based indices,Dependence on Foreign Capital(DFC),Export Ratio of Output(ERO) and Emergy Feedback Ratio(EFR),were established and integrated with some current emergy indices,to fill the evaluation need of industrial ecological system from resource consumption,intra-cycle,trading and disuse interface aspects.The case study of 22 years dynamic of Shunde industrial ecosystem shows that,the new established indices system could fill the special evaluation need of industrial ecosystems,and has the compatibility on multi-scale studies.
