摘要: 基于工业生态学原理,根据生态工业系统的特点,提出了以经济、环境和结构三方面来反映系统发展程度的评价体系. 在此基础上,本研究提出了一系列的评价指标,如:生态生产力指数、 消耗指数、环境影响指数、系统耦合度等,通过对指标的综合得到了经济发展度、环境协调度和结构耦合度3个生态工业系统发展程度的综合评价指标. 为了全面反映系统的发展特性,提出了差异性的概念,用以反映系统的发展均衡程度. 应用这些评价指标对拥有3条高度耦合产业链的鲁北生态工业系统的4个发展阶段进行了研究,结果表明,本研究构建的生态工业系统评价指标能够准确地反映系统的发展状态,指明系统的发展方向.

Abstract: On the basis of the principles of industrial ecology and according to the characteristics of eco-industrial system (EIS), a three factors model, economy-environment-structure, is presented to reflect development degree of an eco-industrial system. Based on the model, a series of evaluation indicators are proposed, such as eco-productivity index (EPI), exergy depletion index (yDP), environment index (EI), and couple degree (CD), etc. Through the integration of evaluation indicators, three composite indicators, economic development degree, environmental harmony degree and structure-coupled degree are obtained. In order to fully express the development characteristics, the conception of development difference is defined. The balance degree of system development can be studied by difference analysis. Finally, the proposed evaluation method is applied to valuate and analyze Lubei eco-industrial system at four different development stages. The result shows that these evaluation indicators can better reflect the degree of system development, which also can be used to guide the direction of system improvement.
