A STUDY ON THE ECO—SPATIAL STRUCTURE OF THE URBAN GROUP
基于生态理论，分析了城市群生态空间结构与经济社会发展的互惠共生和协同演化机制，提出了走廊式组团网络模式，并指出该模式能提升环境容量、促进人与自然和谐。
A balanced eco-spatial structure of urban group with biological diversities in a virtuous circle of ecological environment will promote a speedy and healthy development of economical society of urban group.In terms of ecological theory,this paper makes an exhaustive analysis of mutualism and co-evolutionary mechanism between eco-spatial structure and economic-society development of urban group,and maps out optimized modes of eco-spatial structure of urban group.The analysis is a case study of urban groups on different levels of global,national,provincial and regional scales,on basis of which conclusions are made: ①within scope of urban group,the cities should be reasonably sized and appropriately densified;the spatial combination of urban group ought to be orderly,and its eco-spatial structure ought to be optimized and efficient;the relationship between economical society and eco-spatial environment ought to be that of mutual benefit and co-evolution;② the mode of corridor group network is a sure trend evoked from spatial structure of urban group;③ eco-spatial structure of urban group under the mode of corridor group network can further increase environmental capacity of urban group,and is in favor of harmonious relationship between man and nature.
