中国产业园区循环化改造应用关键物质流典型路径分析方法

产业园区循环化改造是我国在"十二五"期间和今后一个时期内的一项重要工作,也是在园区层面实施循环发展的主要内容。物质流分析(MFA)是产业生态学的核心分析方法,正在成为资源环境管理领域有效的分析工具。通过梳理物质流分析方法的发展历程,指出产业园区循环化改造应用物质流分析存在注重物质规模而忽视环境影响、黑箱过程不利定量研究、小区域研究适用性不强以及隐藏流造成的数据误差等方面问题,同时通过大量调查实践,认为园区循环化改造可从企业开展清洁生产、促进园区内和园区间的产业共生、加强园区资源循环基础设施建设3个领域入手,在将园区全部企业分为生产性企业、再生性企业和资源循环基础设施企业3种类型基础上,提出关键流概念及其识别思路,探索构建物质流路径归类评价方法框架,归纳出8条典型物质流路径,为提升园区物质流管理水平提供方法依据,并选取天津经济技术开发区作为典型案例进行研究,最后对我国产业园区循环化改造应用物质流分析方法进行了展望。

Preliminary exploration of the Chinese industrial park's circularization reform using key material flow analysis

The industrial park''s circular reconstruction is an important task in the 12th Five-Year Plan in China. It is also a chief component of circular development at the industrial-park level. As the primary analytical method of industry ecology, material flow analysis (MFA) is an effective analysis tool in the resource and environment management field. In this paper, we outline MFA''s developmental process and summarize several defects:MFA placed more weight on quantity than influence; its black-box process is unsuited to quantitative study; its applicability is weak in small-scale analyses; and the hidden flow caused deviations. Based on massive investigative practice, three domains were extracted to perform the industrial park''s circularization reform, which were a cleaner production in enterprise; promotion of industrial symbiosis within and among industrial parks; enhancement of the park''s infrastructure construction. The enterprises in the industrial park were sorted into three types:manufacturing, reproductive, and resource-environment infrastructure. A new concept, key flow, was suggested and its recognition method was developed. After constructing the method frame of material flow path classification and evaluation, eight kinds of typical material flow paths were summarized and speculated to enhance the management level of material flow. Simultaneously, we choose TEDA as a typical case study. Finally, the prospect of Chinese industrial park''s circularization reform using material flow analysis was anticipated.
