特大城市中心区阴影区的边界界定及空间特征
Spatial characteristics and boundary defining of shadow areas in public center districts of megacities
摘要
Abstract
Land and building data of 10 Asian megacities' central districts that are defined by the Murphy index are used as the basis of research.The field research and comprehensive analysis of these 10 central district indicate that the shadow area has different connotation in spatial location,dis-tribution of public facilities,development intensity,and architectural form.Subsequently,the defi-ning methods are proposed based on the four aforementioned aspects and the range of the shadow ar-ea in megacities' central districts is determined.The data sorting methods are used to analyze the land-use structure.It is concluded that the shadow area can be divided into four grades.Finally,the time-cost method is used to analyze traffic reachability,and it is found that the low traffic reachabili-ty blocks are apt to become shadow areas.Based on the above analysis and summary,the space law of the shadow area can be scientifically understood and healthy development of central districts can be promoted from rational viewpoint in the future.关键词
