【摘要】 环境问题伴随经济的高速发展日益凸显,工业园区化是区域工业发展的趋势,循环经济是工业园区发展的最佳途径。传统工业园对污染物末端处理的方法已不能满足环境保护的要求。工业园应以循环经济为原则,通过科学、合理的规划,建设资源高效利用的产业链,通过提高资源利用效率,削减污染物的产生,达到保护环境的目标。陕南是我国南水北调的水源涵养区,有很多重要的生态保护区,发展循环经济,对于陕南地区的工业园区可持续发展具重要意义。本文以陕南某工业园为研究对象,在理论分析的基础上,构建生态工业园循环经济综合发展评价指标体系,提出了基于集对分析法的循环经济综合发展水平评价模型。并对工业园实例的循环经济发展水平进行了分析、评价,提出了促进循环经济发展的措施和规划调整建议。本研究获得以下研究成果：(1)建立了一套生态工业园循环经济综合发展评价指标体系。采用SWOT-PEST分析法及根据根据生态工业园的特征,筛选出生态工业园循环经济综合发展水平的评价指标,包括定量指标23个,定性指标8个,建立“总体层—系统层—状态层—变量层”四个层级为结构的循环经济发展水平评价指标体系。其中系统层包括内部环境、外部环境两个层面,变量层包括经济发展、循环性因素、资源能源利用、生态环境、管理因素、政治因素、市场因素、社会因素8类。(2)构建了以循环经济发展水平为目标的评价模型。采用集对分析法作为评价方法,通过模糊综合评价法进行验证,显示该方法计算简便、结果较可靠。评价中结合五元联系数的联系分量间的态势分析,解决了传统评价方法无法对处于同一级别的评价对象进行优劣区分、排序的缺点。(3)采用构建的循环经济发展水平评价模型,对陕南某生态工业园规划进行了分析。分析结果说明,该工业园区循环经济综合发展水平为Ⅱ级,发展水平较高；单项因素中循环性因素及生态环境效益的发展水平高；经济发展及社会因素的发展水平属中等；但资源能源利用因素的循环经济发展水平属低水平,说明园区在资源能源利用方面还有较大的潜力,是今后循环经济发展的重点。(4)在循环经济发展水平评价、分析的基础上,对陕南某生态工业园规划提出了规划调整建议。园区规划应在构建、调整循环经济产业链的基础上,提高工业产值综合能耗,减少工业产值废水产生量、工业产值新鲜水耗以及单位工业用地工业增加值,提高园区循环经济发展水平,增大绿化面积等。更多还原

【Abstract】 Due to the rapid development of domestic market economy, shortage of resources and worsening of environmental conditions have become an increasingly prominent problem, and the traditional industrial park method of treating pollutants can no longer meet pollutant control and environmental protection requirements. A system based on the theory of circular economy and industrial ecology was formed during the development of the eco-industrial park. Through the proper planning of the industrial park in the early stages, an industrial chain is established between enterprises to maximize energy and resource utilization, while also reducing pollutant and waste emission, thus achieving the objective of protecting the environment. Therefore, there is practical significance in the analysis and evaluation of circular economy at the planning level of the industrial park, as this can guide its direction of development, and provide supplement to unreasonable or imperfect parts in the development plan.Taking the planning of an eco-industrial park in Southern Shaanxi for the study in this paper, an index based on the current state of circular economic development is established to evaluate the degree of circular economic development of a given eco-industrial park. At the same time, influences to the atmosphere, water, and solid waste caused by the construction of the park are analyzed, and proposals are put forward to improve the park planning process.This study achieved the following major results:(1) Using the SWOT-PEST method to analyze the internal and external environment of circular economy growth in the eco-industrial park, an overall indicator to evaluate the level of circular economic development based on 23 quantitative and 8 qualitative indicators was selected. A circular economy evaluation index with a four level structure was subsequently developed, including the overall-, system-, condition-, and variable-levels. The overall level reflects the comprehensive development level of circular economy in the eco-industrial park. The system level includes the internal and external layers of the park. Finally, the variable level consists of issues that affect circular economy, such as economic growth, energy and resource utilization, ecological environment, circulating, management, political, market, and social factors.(2) Construct an evaluation model based on set pair analysis to evaluate the level of comprehensive development of circular economy in the industrial park. A definite evaluation procedure is established, and the fuzzy comprehensive evaluation method is used to verify the accuracy of the results. Furthermore, the confirmation of standard values within qualitative indicators is conducted with questionnaire surveys, and the index weights are determined using the factor contribution rate method.This paper utilizes the set pair analysis method as the basis of evaluating the index system. This analysis method has simple calculations and clear principles, and when combined with verification from the fuzzy comprehensive method, it provides reliable results. The evaluation also combines "Set pair situation between the contact component" from the "five-link set number"method to analyze and rank variable layers situated at same orders, which tackles the traditional evaluation method’s inability to analyze similarly situated variable layers, thus distinguishing the pros and cons of such objects, and effectively ranking them in an orderly fashion.(3) Using the eco-industrial park in Southern Shaanxi as an example, the index of degree of circular economic development is used to evaluate the overall circular economy of this park. It was found that the comprehensive level of development of circular economy is grade Ⅱ, which reflects a relatively high degree of development. Out of all the individual factors, the circulating factor and eco-environment effect have the highest level of development; the management system and political and market factors follow closely behind; economic growth and social factors also see moderate levels of development. However, the energy and resource utilization levels are quite low, which implies that there is still potential and room to improve, and special attention should be given to this specific element in the future growth of the park.(4) In analyzing the development level of circular economy at the sample park site, it was discovered that this particular industrial park has weaknesses associated with circular economic development in the following seven areas:the added per value of industrial waste water, comprehensive energy consumption of unit of industrial added value, unit of industrial added value of fresh water consumption, unit of industrial added value of SO2 emissions, industrial output per capita, unit of industrial added value of industrial land, green coverage rate these seven indicators. The industrial park as represented by these seven indices reflects that there is still a relatively large potential for improvement in its circular economy. Some improvements were suggested for these problems, and adjustments were also proposed to enhance the overall planning of the park.更多还原
