中国省域城市生态适宜度综合评价

Comprehensive Evaluation on Urban Ecosystem Suitability of Provinces in China

依据城市生态系统原理,从生产位、生活位、环境位3方面构建了综合衡量城市生态适宜度的指标体系和数学方法,以各个省区地级以上城市作为分析样本,通过对评价区的各领域以及生态适宜度水平综合评价,结果表明:中国省域城市生态适宜度具有的明显区域性差异,城市生态适宜度大致呈现:东部高、中西部低,南方高、北方低的格局,既与区域自然生态条件有关,也同地方社会经济发展、城市建设与管理水平相关。

According to the theory of urban ecosystem,the paper brings up the evaluation indicator system and assessment approach of urban ecosystem suitability from three aspects:production -niches,living-niches, environment-niches.With regional cities of each provinces in China as examples, the results of comprehensive evaluation show that the differences of urban ecosystem suitability in China is obvious,the situation is higher in East China,lower in West China and Mid-China ; higher in South China, lower in Northwest China,which is significantly correlated with the nature condition and the development level of cities.
