【摘要】：随着经济的迅猛发展,我国整体经济形势处在重要的转型阶段,刘易斯拐点的临近,揭示出我国劳动力无限供给的特征开始消失,老龄化问题凸显,城市整体生活水平随着人口不断的提高,生态环境的容量有限,生态的可持续性受到严峻的挑战。近来出现的雾霾,水体污染,地区性气候不稳定等现象,反映出脆弱的生态在人类社会进程中受到了严重的影响。“十八大”召开之后,我国的在生态安全问题上又一次提出了新的建设性理论与措施。针对国内的资源枯竭型城市当前正处在艰难的转型时期,生态环境状况令人堪忧,通过对城市生态安全进行评价分析,以资源枯竭型城市作为研究对象具有重要的意义。本文综合运用了生态学、社会学、管理学、经济学等多学科理论与方法,针对资源枯竭型城市生态安全的特征与评价方法进行深入研究,在对生态安全评价模型和指标权重优化分析的基础上,构建基于压力-状态-影响-响应(PSIR)模型的城市生态安全(Urban Ecological Security)评价指标体系,运用层次分析法与熵权法相结合确定指标权重,以典型的资源枯竭型城市——徐州市为例,通过综合指数法在时间维和空间维上进行生态安全的评价分析,据此比较研究资源枯竭型城市的社会-经济-自然复合系统所产生的生态安全问题,同时给出相应的对策建议。
[Abstract]:With the rapid development of economy, China's overall economic situation is an important transformation stage, Lewis is close to the inflection point, reveals the characteristics of unlimited supply of labor in China began to disappear, highlighting the problem of aging, the whole city living with the population increase, the limited capacity of the ecological environment, ecological sustainability is a challenge. The recent phenomena of haze, water pollution and regional climate instability reflect the serious impact of fragile ecology in the process of human society. After the "eighteen major", our country has put forward a new constructive theory and measures on the problem of ecological security. In view of the difficult transition period of resource exhausted cities in China, the ecological environment is worrying. It is of great significance to evaluate and analyze the urban ecological security based on resource exhausted cities. This paper uses the ecology, sociology, management science, economics and other disciplines theory and methods, analyzes the characteristics and evaluation methods of resource exhausted city in ecological security, the ecological security evaluation model and index weights optimization based on the analysis of the constitutive response based on pressure state impact (PSIR) city ecological security model (Urban Ecological Security) evaluation index system, using AHP and entropy method are combined to determine the index weight, with the typical resource exhausted city -- Xuzhou city as an example, through the analysis and evaluation of comprehensive index method for the ecological security in time dimension and space dimension, the ecological security problems comparison study on resource exhausted city social economic natural complex system, and gives the corresponding countermeasures and suggestions.
