吉林省城镇化与生态环境协调发展的时空演变特征

构建城镇化与生态环境评价体系,评价2000—2012年吉林省城镇化和生态环境综合发展水平及两者耦合协调度.结果表明: 研究期间,吉林省城镇化综合水平呈持续增长态势,其中,经济城镇化贡献份额最大;生态环境综合水平呈波动上升趋势,国家实施振兴东北战略以来生态环境状态、响应、压力都增长较快;耦合协调度呈持续增长趋势,从基本不协调发展为高级协调,由城镇化滞后型转化为生态环境滞后型.中部地区城镇化水平较高,东西部地区生态环境水平高于中部地区,长春市城镇化与生态环境耦合协调度最高,白山市最低;2000—2012年,长吉地区耦合协调度在全省一直处于领先水平,但生态环境滞后水平越来越严重,四平、辽源、松原3市和延边朝鲜族自治州的耦合协调度呈上升趋势,白城市呈现下降趋势.

Spatial-temporal evolution characteristic of coordination between urbanization and eco-environment in Jilin Province,Northeast China.

By building urbanization and eco-environment evaluation index systems, the levels of urbanization and eco-environment, and the degree of their coupling coordination of Jilin Province from 2000 to 2012 were evaluated. The level of comprehensive urbanization showed a continued growth trend, and the economic urbanization contributed the largest share. The eco-environment comprehensive level fluctuated upward. The eco-environment state, response and pressure increased faster since the implementation of the strategy of revitalizing Northeast China and other old industrial regions. Coupling coordination degree between urbanization and eco-environment increased continuously, from uncoordinated status to advanced coordinated status, changing from eco-environment lagged to urbanization lagged. The level of urbanization in central region was higher than east and west regions in Jilin Province, but its eco environment level was low. Coupling coordination degree in Changchun was the highest, and that of Baishan was the lowest. Coupling coordination degree of Chang Ji integrated region was always at the leading level, but the level of eco-environment lagged behind was growing since 2000. Coupling coordination degree of Siping, Liaoyuan, Songyuan and Yanbian increased, but that of Baicheng decreased.
