煤炭资源型城市生态-经济-社会协调发展分析——以淮南市为例

以典型的煤炭资源型城市淮南市为例,构建“经济-社会-生态”三维系统指标体系,通过熵权法、耦合协调发展模型和灰色关联系数研究了该系统2002—2016年间的发展,从宏观角度分析淮南市多维关系的协调发展.结果表明: 生态子系统所占权重最大,其发展水平整体呈U型(先减后增),并对综合发展水平造成显著影响;三维耦合系统总体呈上升态势,耦合绝对水平较低,生态系统压力在逐渐增大的过程中制约经济和社会的发展,并反作用于协调发展水平;经济发展和经济活力分别对社会和生态子系统发展产生积极影响,社会发展对生态子系统影响较大,环境现状的改善对经济和社会发展具有支撑作用;在淮南市转型过程中,需保持经济的稳定快速发展,增加对社会发展和环境污染治理方面的投入力度,同时注重生态的支撑能力,避免对社会经济发展产生限制作用.

Analysis on the coordinated development of ecology-economy-society in coal resource cities: A case study of Huainan,China

We constructed a multi-dimensional indicator system of “economic-social-ecological” with Huainan City, a typical coal resource-based city, as an example. The development of the system from 2002 to 2016 was examined by entropy weight method, coupled coordination development model and grey correlation coefficient. The coordinated development of multi-dimensional relationship in Huainan City was analyzed from a macro perspective. The results showed that the ecological subsystem had the largest weight, whose development level being U-shaped as a whole, first decreasing and then increasing, with significant impact on the comprehensive development level. The ternary coupling system was generally on the rise, with low absolute level of coupling. With the increases of ecosystem pressure, it would restrict the economic and social development and counteracted the coordinated development level. Economic development and economic vitality had a positive impact on social and ecological development, while social development had a greater impact on ecological subsystems. The improvement of environmental status had a supporting effect on economic and social development. In the transformation process of Huainan, it should maintain stable and rapid economic development, increase investment in social development and environmental pollution control, as well as pay attention to ecological support capacity to avoid restricting social and economic development.
