【摘要】：城市是一类社会-经济-自然复合生态系统,城市的可持续发展指标体系和评价方法是衡量城市经济、社会、环境状况及可持续发展能力的重要手段。采用全排列多边形综合图示法,以中国277个地级及地级以上城市为研究对象,建立了不同规模城市的可持续发展指标体系,包括经济发展、社会进步、生态环境3类24项指标,对其2000—2010年的可持续发展能力进行了综合评价。研究结果表明:从不同城市规模类型间横向对比分析来看,随着城市规模的增大,经济发展、社会进步和可持续发展综合指数相应提高,生态环境指数却随之下降。从不同规模城市类型内的时间序列分析对比来看,2000—2010年不同规模城市的经济发展、社会进步、生态环境指数各个方面均有显著提高,可持续发展综合指数也伴随着提升。并且,巨大特大型城市在生态环境保护方面提高幅度最大;大型城市在社会进步方面提高幅度最大;中小型城市在经济发展和可持续发展综合能力方面提高幅度最大。但截止到2010年,不同规模城市的可持续发展综合指数均为Ⅲ级,可持续发展能力仅处于一般水平。探究了中国不同规模的城市可持续发展过程中面临的诸多问题,然后提出相应的对策建议,为今后的新型城市化建设提供参考。
[Abstract]:City is a kind of social-economy-natural complex ecosystem. The index system and evaluation method of sustainable development of city is to measure urban economy and society. By using the method of polygon comprehensive graph, the sustainable development index system of cities of different sizes has been established with 277 cities at or above the prefectural level in China as the research objects. A comprehensive evaluation of the sustainable development capacity of 24 indicators, including economic development, social progress and ecological environment, is carried out from 2000 to 2010. The results show that: from the perspective of horizontal comparative analysis among different urban scale types, With the increase of urban scale, the comprehensive index of economic development, social progress and sustainable development increases accordingly. According to the time series analysis of different scale cities, the economic development, social progress and ecological environment index of different scale cities from 2000 to 2010 have been significantly improved. The comprehensive index of sustainable development is also accompanied by an increase. Moreover, the ecological environment protection of large and super large cities is the largest, while the social progress of large cities is the largest. Small and medium-sized cities have seen the greatest improvement in their comprehensive capacity for economic development and sustainable development. However, by 2010, the composite index of sustainable development for cities of different sizes was grade III, The ability of sustainable development is only in the general level. This paper probes into many problems in the process of sustainable development of cities of different sizes in China, and then puts forward corresponding countermeasures and suggestions to provide reference for the construction of new type urbanization in the future.
