水泥-电力行业的产业共生网络构建及区域案例研究

水泥工业作为工业生态系统的汇，能够多样化地利用其他行业的副产物，这种典型的产业共生模式可以通过减少资源和能源的消耗带来显著的CO₂减排效果.由于产业共生在水泥行业具有一定的普遍性及巨大的CO₂减排潜力，所以对水泥工业产业共生现状的了解与分析就显得尤为重要；而通过对产业共生现状的全面了解，才能对现有水泥行业产业共生的程度进行分析，并以此为参照，对未来不同政策与情景下的CO₂减排潜力进行量化与评估.为实现对产业共生实际情况的模拟，以水泥-电力行业的产业共生为例，采用最优化的方法，提出了一套基于一般统计数据来模拟产业共生实际情况的系统方法，将技术、经济与政策3类不同的决策变量影响纳入模型，以模拟出最接近真实情景的产业共生情况.为验证模型的有效性，对新乡市水泥-电力行业实际的产业共生情况进行分析.结果表明:新乡市水泥-电力行业间存在普遍的产业共生现象，实地调查中有77.8%（21家）的水泥制造企业利用粉煤灰作为水泥制造的原材料.将一般统计数据与实地调查数据对比发现，一般统计数据能较好地反映企业实际物质投入产出情况；利用一般统计数据，模型对新乡市产业共生网络结构模拟的准确率高达92.6%，显示该模型能较为有效地对产业共生的实际情况进行模拟. 

Industrial Symbiosis Network Construction between Cement and Coal-Fired Power Industries and the Case Study

Cement industry plays the role of hub in the industrial ecosystem, which is capable of diversifying the use of wastes and consuming large amounts of byproducts from various other industries. This typical mode of industrial symbiosis can bring significant CO₂ emission mitigation effect through reducing the consumption of resources and energy. Due to the prevalence of industrial symbiosis in cement industry and its huge CO₂ emission mitigation potential, it is particularly important to investigate and understand the realistic status of industrial symbiosis in order to analyze the degree of industrial symbiosis and then to use it as a reference to quantify and evaluate the potential of CO₂ emission mitigation under different scenarios in the future. In this study, in order to simulate the realistic status of industrial symbiosis, a systematic framework was proposed to simulate the realistic status of industrial symbiosis between cement and coal-fired power industries by using the method of optimization. This method incorporates the influences of three different decision variables of technology, economy and policy into the model to simulate the symbiosis of the industries that were closest to the real situation. The effectiveness of this framework was verified by the case study in Xinxiang City, Henan Province. The results show that 77.8% (21 companies) of the cement manufacturing enterprises in the field survey use fly ash as the raw material for cement manufacturing, indicating a general industry symbiosis phenomenon between the cement and coal fired industries in Xinxiang City. The general statistics are compared with the field survey data in order to guarantee that the general statistical data can reflect the actual material input and output of the enterprises. Ultimately, the accuracy of the final model for the simulation of the industrial symbiosis network structure in Xinxiang City is as high as 92.6% inputting the general statistical data, suggesting that this model can effectively simulate the actual situation of industrial symbiosis.
