【摘要】：研究目的:以2005—2014年的城镇化与生态环境综合指数为基础,运用重心模型测算安徽省城镇化发展与生态环境匹配度,探讨两者之间的交互作用,为政府在城镇化进程中如何保护环境提供决策依据。研究方法:熵值法、重心模型。研究结果:(1)安徽省城镇化发展和生态环境综合指数地区差异显著,生态环境质量随着城镇化水平的提升呈下滑趋势,"凸""凹"相致,逆向明显;(2)城镇化重心与生态环境重心在东西方向的偏移幅度明显大于南北方向的偏移幅度;(3)城镇化重心、生态环境重心均向西南偏移,但前者的变化过程较后者更为明显;(4)城镇化与生态环境匹配度演化轨迹均呈M型,但整体匹配性较差,匹配年份仅占22.22%,平均匹配度仅为-0.1605。研究结论:2005—2014年安徽省城镇化水平与生态环境状态整体处于较不匹配状态,提高城镇土地利用绩效,坚持集约、绿色和低碳的新型城镇化道路,是未来安徽省城镇化演进中破解环境问题的关键。
[Abstract]:Objective: based on the comprehensive index of urbanization and ecological environment from 2005 to 2014, using the center of gravity model to calculate the matching degree of urbanization and ecological environment in Anhui Province, and to explore the interaction between them.For the government in the process of urbanization how to protect the environment to provide decision-making basis.Research methods: entropy method, barycenter model.Results: (1) the regional differences of urbanization development and ecological environment comprehensive index in Anhui Province are significant. The ecological environment quality is declining with the improvement of urbanization level, which is caused by "convex" and "concave".(2) the shift between the center of gravity of urbanization and the center of gravity of ecological environment in east-west direction is obviously larger than that in the direction of north and south, and the center of gravity of ecological environment is all shifted to the southwest.But the change process of the former is more obvious than that of the latter.) the evolution track of urbanization and ecological environment matching degree is M-type, but the overall matching degree is poor, the matching year is only 22.22%, the average matching degree is only -0.1605.Conclusion: from 2005 to 2014, the urbanization level and ecological environment of Anhui Province are in a relatively mismatched state, and improve the urban land use performance, adhere to the intensive, green and low-carbon new urbanization road.It is the key to solve the environmental problems in the evolution of urbanization in Anhui Province in the future.
