【摘要】 生态城市是人类在环境承载力范围内,根据生态学和城市生态学原理,运用各种合理的传统技术和现代科学技术手段建造的生态环境健康、社会文明发展、经济高效运行的可持续发展的复合生态系统。生态城市的建设能有效地优化城市人居环境,全面提升城市居民的生活质量,解决目前所面临的城市问题。国内外许多城市在制定城市发展战略时把生态城市作为发展目标。 重庆市于1997年提出了建设山水园林城市的发展目标,为城市发展指明了方向,在建设实践中起到了很大的积极作用。但是山水园林城市仅是生态城市的初级形态,只能作为重庆城市建设的短期目标。目前,对重庆城市长期的建设目标和发展模式进行深入探讨的研究还比较少。 本文采用系统分析、统计分析、比较分析、定性与定量研究相结合的方法,在分析重庆建设山水园林城市概况的基础上,提山生态城市是重庆城市发展的最终目标,探讨了重庆具体的生态城市发展模式和建设内容,构建了重庆生态城市综合评价指标体系,并对重庆1998-2003年的城市生态系统建设状况进行综合评价与比较分析,提山重庆建设生态城市的一些对策。研究得山以下结论: (1) 通过对重庆城市生态系统成分分析得出:重庆生态城市建设的主要有利因子有地理区位、旅游资源、气候条件、坚实的工业基础、经济运行环境、建筑业发展迅速、人口自然增长率较低、居比生活条件和生活水平提高快、科技水平先进等;主要限制因素有水资源和土地资源利用率低、环境污染严重、经济区域发展不平衡、经济总量小、农业人口基数大、人口素质较低、生态意识薄弱等。 (2) 重庆生态城市的发展模式是“资源—经济—文化”复合型生态城市:利用重庆“山”、“水”等自然资源的优势,在现有山水园林城市的基础上,设计并构建合理的城市发展空间,充分调动一切促进重庆经济、社会发展的作用力,按照生态安全、生态卫生、生态产业、生态景观和生态文化的层面逐步深入,将重庆建设成为城乡共荣的人与自然和谐共处的现代、文明、高雅的社会、经济、生态协调发展的生态城市。更多还原

【Abstract】 The eco-city is a composite ecosystem constructed by human in which harmonious nature and civilized society and efficient economy can develop sustainably, using diversified traditional and modern technology on the principle of ecology and urban ecology within the limits of environmental load capacity. The construction of eco-city can optimize efficiently urban resident habitation, advance roundly quality of resident living, and solve the city problem. At present, eco-city has become the direction of either domestic or overseas city.Garden city is put forward for the direction of Chongqing in 1997, which promotes the construction of Chongqing city in the past several years. However, garden city is the only elementary form of eco-city. It is just the short-term direction of Chongqing city. Presently, the long-term development target and model of Chongqing are lack of in-depth discussion.Systems analysis, statistic analysis, comparative analysis, qualitative analysis and quantitative analysis are used associatively in this paper. The building of garden city of Chongqing is summarized as the basis of this paper. Eco-city is put forward for the final development target of Chongqing. The model and contents of Chongqing eco-city are discussed. The integrated evaluating indices system of eco-city is set up, which is used to appraise the development level of Chongqing city in 1998-2003.Finally, this paper brings forward some countermeasures for the construction of eco-city. The conclusions are carried out as follows:(1) Results of urban system analysis of Chongqing: The advantageous factors of eco-city building include situation, tourism resources, climate resources, steady industrial foundation, economical running condition, zooming construction, lower natural growth rate, elevated conditions and standard of people’s living, advanced science and technology, and so on. The disadvantageous factors include lower efficiency of water resources using, serious environment pollution, lopsided regional economy development, lower gross economy, excessive agriculture population, lower quality of population, feeble ecological consciousness.(2) The development model of Chongqing eco-city is "Resource-Economy-Culture" Composite Eco-city. Using the advantage of "Shan" and "Shui" in Chongqing, on the base of garden city, thereasonable urban spatial structure is designed. In order to realize the modern, civilized, exquisite eco-city in which nature, society and economy can develop in phase, where people and nature coexist harmoniously, Chongqing must mobilize any power to construct ecological security, ecological sanitation, ecological industry, ecological landscape and ecological culture.(3) The scope of Chongqing eco-city is the 40 districts (counties, cities) . The contents of building eco-city comprise:①Ecological security. To improve the environment quality and to stabilize population growth are the main tasks of the advanced economic sphere. The ecological economic zone in Three Gorges Reservoir area basically protect environment and construct zoology. And the assignment of economic corridor in west Chongqing is to protect and harness water resources.②Ecological sanitation: Spreading the technology of ecological water closet step by step and setting up community ecological rotative stations.③Ecological industry: Energetically developing ecological agriculture, the point of foothill in west Chongqing is to grow dry eco-agriculture, the point of suburb is suburban cco-agriculture, the Three Gorges Reservoir area along the Changjiang River should give priority to the efficient eco-agriculture characterized by foodstuff and oil crops, aquiculture, forestry and pomiculture, the southeast of Chongqing is to develop eco-stockbreeding, herbal medicine and forestry. The system of Ecological industry is constructed by pushing cleaner production and setting up eco-industrial park. To realize ecological tertiary industry, the concept of developmental consumption must be built up, in addition, pushing functional economy and promoting eco-tourism.④Ecological landscape: The ecological landscape planning should be put up firstly to optimize the structure and course of landscape. In this way, the negative influence of economy development on the environment can be lightened.⑤Ecological culture: Ecological culture is constructed by establishing civilized regulations, by strengthening ecological education, and by building ecological architecture and uptown.There are elementary phase (before 2015), growing phase (2015-2030), advanced phase (after 2030) of Chongqing eco-city the construction.(4) The integrated evaluating indices system of Chongqing eco-city includes final target level, sub-target level, rule level and index level. The final target level is social-economic-natural developing harmoniously urban ecosystem. The sub-target level contains harmonious nature, civilized society and efficient economy 3 indices. The rule level comprises virescence level, environment quality, prevention of pollution, development of economy, index of population, material and cultural life, social security 7 indices. The index level has 34 indices together.(5) Using theAHP and weighting exponent, regarding 1998 as benchmark year, by computer,更多还原
