采用墨菲指数界定的10个亚洲特大城市中心区用地及建筑作为数据基础，通过对这10个中心区实地调研与综合分析，发现阴影区在区位空间分布、公共设施分布、开发强度和建筑形态4个方面具备具体特征内涵。然后，从这4方面提出界定方法，确定特大城市阴影区范围。采用数据排序法分析用地构成，总结阴影区用地可按照比例大小分为4个等级。最后，采用时间成本法分析交通特征，发现交通可达性低的地块容易产生阴影区。根据以上分析和归纳，可科学认知阴影区的空间规律，从理性推进的角度实现中心区的健康发展。

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.
