| 摘 要： | 以长江经济带11个省（市）为研究对象，基于耦合协调模型构建城市化与森林生态承载力评价指标体系，运用熵权法测算2005-2014年长江经济带城市化与森林生态承载力综合水平，分析其耦合协调关系及时空演化规律。研究结果表明:①长江经济带城市化与森林生态承载力综合水平分别处于上升趋势，总体呈现“中东部较强，西部较弱”的分布格局，其中城市化指数10 a间共增长0.070 8，森林生态承载力指数10 a间共增长0.057 9。②长江经济带城市化与森林生态承载力协调关系一直处于上升趋势，协调度值从0.532 9上升到0.614 4，经历了从“低度协调”过渡到“中度协调”阶段，整体协同作用初显效果，但城市化发展滞后是制约两者协调发展水平提升的主要原因。③区域内各省（市）协调度存在一定差异，东中西部地区依次呈递减趋势，呈现“良好协调-城市发展型”“中度协调-绿色发展型”“低度协调-绿色发展型”“中度失协调-绿色发展型”的空间分布趋势。总体来看，长江经济带的森林生态承载力优先于总体城市化是导致大部分城市两系统间耦合协调度处于中低水平的重要原因。因此，在推进长江经济带建设中仍要正确处理好生态环境和经济发展的关系，探索协同推进生态优先和绿色发展新路径。

| Abstract: | This article focused on 11 provinces on the Yangtz River Economic Belt (YREB). Firstly, it established a systematic evaluation index system for urbanization and forest ecological carrying capacity (FECC). Secondly, it used an entropy weight method to measure the integrated level of the urbanization and the FECC. Finally, the change trends of the urbanization and the FECC on the YREB during 2005-2014 were revealed through the coupling coordination model. The results showed that:(1) there had been a growing trend in the integrated level of the urbanization and the FECC on the YREB, showing a distribution pattern of "strongest in the middle and east of China and weakest in the west of China", the index of urbanization increased by 0.070 8 and the index of forest ecological carrying capacity increased by 0.057 9; (2) there had also been an upward trend in the coordinated degree between urbanization and the FECC in the YREB cities, the degree of coupling coordination rose from 0.585 7 in 2005 to 0.651 1 in 2014; it had experienced a transition from "low coordination" to "moderate coordination"; the overall synergy began to appear but the lag in the urbanization was the main factor constraining the improvement of the coordinated development; (3) there were certain differences in coordination levels among provinces; the level of the coordination had decreased from the east to the west region, presenting the spatial distribution trend of "good coordination-urbanization development", "medium mismatches-green development", "low coordination-green development" and "moderate coordination-green development". Overall, the FECC taking precedence over the urbanization on the YREB is an important reason why the coupling coordination between two systems in most cities is at medium-low level. Therefore, in promoting the construction of the YREB, we must correctly handle the relationship between the ecological environment and economic development, and explore the synergetic mode to promote ecological priorities and new approaches to green development. |
