摘　　要：信息时代,居民生活逐渐向线上转移,已有研究表明线上生活推动了相应生活空间的重构,但其空间结构及成因仍待系统研究。本文选取与居民日常生活紧密相关的八类线上生活,利用武汉市联通用户手机App使用数据,以规则网格为单位,基于这些App的使用人数占比和人均使用时长构建八类线上生活的综合使用指数,而后利用冷热点分析和层次聚类,初步探究了武汉市居民线上生活的空间结构。发现其与传统生活存在很大差异:(1)就普及程度和使用强度而言,除外卖生鲜外,其他七类均遵循高值指标和热点多分布于郊区的反中心化规律,部分活动还呈现泛中心化的特征。(2)从热门活动的数量和内容来看,中心城区外围热门活动数量多于核心区,线上线下融合型活动居多;近郊区核心区热门活动数量多,各类线上活动发展得较为均衡;近郊区外围热门活动数量少,热门活动多为完全线上型。(3)总结上述特征,居民线上生活空间呈现“环形山”形态的圈层式扇形镶嵌结构。线上生活因弥补了郊区传统生活设施的不足而呈现与之互补的反中心圈层递增规律,同时,地理区位、建设条件、人口构成等因素影响下的线上生活差异使得不同人群集聚片区以扇形板块镶嵌其中。本文从线上生活的角度补充了传统居民生活空间理论,系统地总结了居民线上生活的空间结构,为信息时代城市生活空间的建设提供了参考。In the information age,the lives of residents are gradually shifting to online.Existing studies have shown that online life has promoted the reconstruction of living spaces.However,its spatial structure and causes still need to be studied systematically.In view of this,this article selects eight categories of online life closely related to residents'daily life.Based onthe mobile App usage data of Wuhan Unicom users,the two indicators:the proportion of usersand the average usage time are calculated in regular grids,so as to construct the comprehensiveusage index of eight types of online life.Then,using cold-and-hot-spot analysis andhierarchical clustering methods,the spatial structure of Wuhan residents'online life waspreliminarily explored.We find that there are many differences between online life andtraditional life:(1)In terms of popularity and use intensity,except for food delivery,the otherseven categories follow the anti-central law of high-value index and hot spots mostlydistributed in the suburbs,and some activities also show the characteristics of pancentralization.(2)The number of popular activities in the periphery of the central urban area ismore than that in the core area,and online and offline combined activities are in the majority.There are a large number of popular activities in the core area of suburban area,and theseonline activities develop in a relatively balanced way.The number of popular activities in theperiphery of suburban area is small,and most of them are completely online.(3)According tothe above characteristics,the online living space of residents presents a circular sector mosaicstructure in the form of"crater".Online life makes up for the deficiency of traditional livingfacilities in the suburbs,so it presents an increasing law of anti-central circle complementary totraditional life.At the same time,the differences of online life under the influence ofgeographical location,construction conditions,population composition and the other factorsmake different groups of people inlaid in
