【摘要】：在生态工业园中以循环经济为指导调整产业结构,构建合适的产业链,能有效的解决经济发展与资源环境之间的矛盾。在实际工作中,规划实施者主要是从管理学和经济学的角度出发,按照产业链的生成机制及相关特性确定产业链的类型及发展规模,而且为了实现经济效益盲目的追求产业链的延伸和拓展,造成资源浪费和环境污染。因此,在生态工业园中,考虑资源及环境约束对产业链进行优化和评价,有重要的意义。本文在对生态工业园中产业链优化及评价相关基础理论和研究方法进行阐述和分析的基础上,以工业生态学理论为指导,对产业链影响因素及确定原则进行详细分析。根据生态工业园所在地资源特征及园区产业定位,确定可能在工业园中发展的产业链,建立以资源及环境为约束条件的经济效益和污染物减少为目标的优化模型,并建立考虑污染物排放条件的数据包络模型,对产业链进行定量优化及评价。以甘肃省某生态工业园为例,按照一次建成所有产业链及延伸产业链两种情况,确定可能在工业园发展的产业链,并从资源约束和环境约束的角度分情景进行模型计算,并将模型优化的结果与产业政策及工业园规划规模进行对比分析。研究结果表明在资源可利用量及环境容量有限的情况下,适宜发展聚丙烯、二甲醚、电石、醋酸乙烯产业链,并应限制聚氯乙烯、聚乙烯等高耗能、高污染产业链的发展。同时应鼓励风电及光电产业的发展,并考虑矿井疏干水的综合利用,减少电力资源及水资源对工业园的发展限制。
[Abstract]:In the Eco-industrial Park, the contradiction between economic development and resource environment can be effectively solved by adjusting the industrial structure under the guidance of circular economy and constructing an appropriate industrial chain. In the actual work, the implementer of the planning mainly sets out from the angle of management and economics, and determines the type and development scale of the industrial chain according to the generation mechanism and related characteristics of the industrial chain. And in order to achieve economic benefits blindly pursue the extension and expansion of the industrial chain, resulting in waste of resources and environmental pollution. Therefore, it is of great significance to optimize and evaluate the industrial chain considering the resource and environment constraints in the eco-industrial park. On the basis of expounding and analyzing the basic theories and research methods of industrial chain optimization and evaluation in eco-industrial parks, and guided by the theory of industrial ecology, this paper makes a detailed analysis of the influencing factors and determining principles of industrial chain. According to the local resource characteristics and industrial location of EIP, the industrial chain that may be developed in the industrial park is determined, and the optimization model of economic benefit and pollutant reduction with resource and environment as the constraint condition is established. A data envelope model considering pollutant discharge condition was established to optimize and evaluate the industrial chain quantitatively. Taking an ecological industrial park in Gansu Province as an example, according to the two conditions of establishing all industrial chains and extending industrial chains at one time, the industrial chains that may be developed in the industrial parks are determined, and the models are calculated from the perspective of resource constraints and environmental constraints. The results of model optimization are compared with industrial policy and industrial park planning scale. The results show that the industrial chain of polypropylene, dimethyl ether, calcium carbide and vinyl acetate should be developed under the condition of limited resource availability and environmental capacity, and the development of high energy consumption and high pollution industrial chain such as PVC and polyethylene should be restricted. At the same time, the development of wind power and optoelectronic industry should be encouraged, and the comprehensive utilization of mine drainage should be considered to reduce the limits of power resources and water resources on the development of industrial parks.
