【摘要】：“十三五”规划重申了节约资源、保护环境的重要性,两型社会的建设表明经济发展和生态环境建设统筹兼顾的发展要求。产业是经济发展的基石,产业结构的优化转型极大地推动了我国经济发展水平的提高。但步入21世纪,发展速度之后的发展质量问题凸显。第二产业中的工业污染问题、第一产业中的旱涝灾害及农药化肥使用量等都会影响生态安全的稳定。第三产业的环境破坏性相对较小,但其中的运输业对生态安全的威胁也越来越大,汽车尾气已经成为严重雾霾天气的主要诱因。产业结构与生态安全之间存在着紧密相关性,产业结构的优化发展对促进经济的可持续发展并有效维持生态安全意义重大。本论文以生态环境恶化、经济可持续发展遭遇阻碍、环境效益与经济效益并重越发重要的社会发展现状为研究背景,以提出产业结构影响下合理的城市生态安全应对策略为研究目标。首先,对产业结构、生态安全及两者关系的有关概念、理论进行介绍,并在分析EKC(environmental kuznets curves)假设检验对本文研究内容的启发性和PSR(Pressure-States-Response,压力-状态-响应)模型对本文研究内容适用性的基础上,构建产业结构视角下的城市生态安全PSR评价模型。其次,基于构建的PSR模型,利用未确知聚类方法对我国24个省GDP排名第2、4位市的生态安全状况进行聚类分析,得到各样本对各类的隶属度,并分析聚类结果产生差异的原因。最后,通过对聚类结果的分析,有针对性的提出优化产业结构、提升城市生态安全质量的对策建议,以期促进城市经济发展水平的持续提高和生态安全的长久稳定。
[Abstract]:The 13th Five-Year Plan reaffirmed the importance of saving resources and protecting the environment. The construction of the two types of society shows the development requirements of economic development and ecological environment construction.Industry is the cornerstone of economic development. The optimization and transformation of industrial structure has greatly promoted the improvement of economic development level in China.But enter the 21 st century, the development quality problem after the development speed highlights.The problem of industrial pollution in the secondary industry, the drought and flood disaster in the primary industry and the use of pesticides and fertilizers will affect the stability of ecological security.The environmental damage of the tertiary industry is relatively small, but the transportation industry is threatening the ecological security more and more, and the automobile exhaust has become the main cause of severe haze weather.There is a close correlation between industrial structure and ecological security. The optimization and development of industrial structure is of great significance to promote the sustainable development of economy and to maintain ecological security effectively.In this paper, the background of this thesis is the social development situation, where the ecological environment deteriorates, the economic sustainable development encounters obstacles, and the environmental benefits and economic benefits become more and more important.The aim of this paper is to put forward a reasonable strategy of urban ecological security under the influence of industrial structure.First of all, the concept and theory of industrial structure, ecological security and their relationship are introduced.Based on the analysis of the enlightenment of EKC(environmental kuznets curves hypothesis test and the applicability of PSR-Pressure-States-Response model to the content of this paper, a PSR evaluation model of urban ecological security is constructed from the perspective of industrial structure.Secondly, based on the constructed PSR model, unascertained clustering method is used to analyze the ecological security status of the 2nd and 4th cities in the second place of GDP ranking in 24 provinces of China, and the membership degree of each sample is obtained, and the reasons for the difference of the clustering results are analyzed.Finally, through the analysis of the clustering results, the paper puts forward the countermeasures and suggestions to optimize the industrial structure and improve the quality of urban ecological security, in order to promote the sustainable improvement of the level of urban economic development and the long-term stability of ecological security.
