长江中游城市群城镇化视角下产业结构与生态环境耦合协调关系研究

Research on coupling coordination relationship of industrial structure and ecological environment from the perspective of urbanization in the Middle Reaches of the Yangtze River

城镇化、产业结构、生态环境三者之间有着密不可分的联系,这种联系随着区域和时间的不同而存在不确定性.该文以长江中游城市群作为研究区,通过建立评价指标体系,运用熵权法并引入耦合协调度模型,从时空两个维度,对2006年～2015年区域内的28个地级市在城镇化、产业结构、生态环境三者间的耦合协调度进行分析.研究结果表明:1)研究期内,长江中游城市群区域发展耦合协调度呈现上升趋势,但整体上升不明显,部分地区濒临失调;2)武汉、长沙、南昌三个省会城市耦合协调度水平较高,地市之间差异较大,明显存在区域不协调的状况;3)长江中游城市群中,襄阳、宜昌、黄石、株洲、衡阳市近年来发展较好,耦合协调度增高,这表明在城镇化以及经济高速发展背景下,各地市对产业结构的调整和生态环境保护的重视;但对于长江中游城市群大区域来说,还需要重视整体的统筹协调发展.

Urbanization,industrial structure and ecological environment are inextricably linked.This kind of connection has uncertainties with different regions and times.In this article the urban agglomerations was used in the Middle Reaches of the Yangtze River(MRYR)to establish an evaluation index system,and an entropy method along with a coupling coordination model were introduced.Then the degree of coupling and coordination between the industrial structure and the ecological environment was analyzed in both time and space dimensions in the 28 cities from 2006 to 2015.The results of the study indicate as follows.1)During the study period,the coupling coordination of regional development in the MRYR showed an upward trend,but the overall increase was not obvious,and some areas were on the verge of maladjustment;2)Coupling coordination level of the three provincial capitals,Wuhan,Changsha,and Nanchang,is relatively high,and there are significant differences between cities.There is clearly a situation of regional incoherence.3)Among the urban groups in the MRYR,Fuyang,Yichang,Huangshi,Zhuzhou,and Hengyang have developed well in recent years,and the degree of coupling coordination have increased.This shows that under the background of urbanization and rapid economic development,local cities attach importance to the adjustment of the industrial structure and the protection of the ecological environment.However,for the large urban agglomerations in the MRYR,it is also necessary to pay attention to overall coordinated development.
