【摘要】：生态环境承载力是生态文明建设的基础,研究生态环境承载力对于深入实施生态文明建设具有重要意义.福建省在生态文明建设方面走在全国前列,通过研究福建省的生态环境承载力情况,有助于更好地推进福建省生态文明建设.基于DPSIR概念模型构建了福建省生态环境承载力评价指标体系,采用TOPSIS分析法和障碍度模型对福建省2000—2015年生态环境承载力状况和障碍因子进行了评价分析.结果表明:总体而言,福建省生态环境承载力综合贴近度不断上升,从2000年的0.09981上升到2015年的0.89625,表明福建省生态环境承载力水平稳步提升;从分类指标来看,驱动力、状态、影响和响应子系统评价指数均呈不同幅度的上升趋势,而压力子系统评价指数呈下降趋势,表明福建省在生态环境治理方面所做的努力是卓有成效的,生态文明建设压力相对减小;从障碍度分析来看,就分类指标而言,响应子系统承载力是影响福建省生态环境承载力的主要因素系统.就主要障碍因素而言,在研究期内,影响福建省生态环境承载力的主要障碍因素包括能源消耗弹性系数、城市环境基础设施投资、环境保护投资占GDP的比例等.基于上述结论,本研究最后提出了相应的对策措施.
[Abstract]:Ecological environmental carrying capacity is the basis of ecological civilization construction, and the study of ecological environmental carrying capacity is of great significance for the further implementation of ecological civilization construction. Fujian Province is in the forefront of the country in the construction of ecological civilization. Through the study of the ecological environment carrying capacity of Fujian Province, it is helpful to promote the construction of ecological civilization in Fujian Province. Based on the conceptual model of DPSIR, the evaluation index system of ecological environmental carrying capacity in Fujian Province was constructed. The status and obstacle factors of ecological environmental carrying capacity in Fujian Province from 2000 to 2015 were evaluated and analyzed by using TOPSIS analysis method and obstacle model. The results show that, overall, the comprehensive closeness of ecological environmental carrying capacity in Fujian Province continues to rise, from 0.09981 in 2000 to 0.89625 in 2015, indicating that the level of ecological environmental carrying capacity in Fujian Province has increased steadily. From the point of view of classification index, the evaluation index of driving force, state, influence and response subsystem shows an upward trend of different ranges, while the evaluation index of pressure subsystem shows a downward trend. The results show that the efforts made in ecological environment management in Fujian Province are fruitful, and the pressure on the construction of ecological civilization is relatively reduced. From the analysis of obstacle degree, as far as the classification index is concerned, the bearing capacity of response subsystem is the main factor system that affects the carrying capacity of ecological environment in Fujian Province. As far as the main obstacles are concerned, during the study period, the main obstacles affecting the carrying capacity of ecological environment in Fujian Province include the elasticity coefficient of energy consumption, the investment of urban environmental infrastructure, the proportion of investment in environmental protection to GDP, and so on. Based on the above conclusions, the corresponding countermeasures are put forward at the end of this study.
