长株潭城市群生态空间结构优化研究

Study on Optimization of Ecological Spatial Structure in Chang-Zhu-Tan Urban Agglomeriation

以生态学、地理学、社会学、经济学理论为指导,系统地分析长株潭城市群生态空间结构存在的主要问题及其影响因素,提出了生态空间结构优化的目标和策略。研究结果表明:生态基质尚未形成,绿地斑块之间自然生态过程缺乏联系,重要的自然空间廊道不畅,资源与环境的承载力逐渐减弱是长株潭城市群生态空间结构存在的主要问题,这些问题的形成受自然环境因素及社会经济因素的综合影响。政府应通过各种途径改善区域性基础设施,提升长株潭的区位优势,并通过区域政策、城市规划等宏观调控手段,引导长株潭城市群实现生态空间结构的优化重组,促进城市群整体的可持续发展。

This paper taking ecology,geography,sociology,economic theory as a guide,systematicly analyze the main problems of Chang-Zhu-Tan urban agglomeration ecological spatial structure and their impact factors and shows the structural optimization of the ecological space of the goals and ambitions.The research results show that： Eco-matrix has not yet formed;green patches lack connections between them during natural ecological processes,the important natural space corridor is somewhat blocked,and also,with the capacity of resources and environment gradually weakened.The form of these problems are the comprehensive consequences of Chang-Zhu-Tan urban agglomeration poor ecological spatial structure of the main problems that the natural factors of the formation of closed and the combined effects of socio-economic factors.Government should through various means to improved regional infrastructure enhance the advantage of Chang-Zhu-tan,and through regional policy,urban planning,such as macro-control means guide the Chang-Zhu-tan to achieve the optimal spatial structure of ecological restructure and promote the overall group of cities sustainable development.
