工业代谢分析方法作为生态工业的主要分析手段 ,借鉴了自然生态的概念 ,从生态环境的角度出发 ,追踪和分析物流、能流的走向 ,找出生产系统中造成污染的原因和主要环节及其相应对策。本文尝试运用生态工业中的代谢分析方法对煤炭利用过程造成的污染情况加以分析 ,提出相应地改进模型 ,并在此基础上找出环境最优的产品结构 ,物流组成及流量 The industrial metabolic analysis method, as the main analysis method of the ecological industry, draws on the concept of natural ecology, and from the perspective of the ecological environment, tracks and analyzes the trends of logistics and energy flow to identify the causes and main links of pollution in the production system. Corresponding measures. This paper attempts to use the metabolic analysis method in the eco-industry to analyze the pollution caused by the coal utilization process, propose corresponding improvement models, and on this basis find out the optimal environmental product structure, logistics composition and flow
