摘　　要：以杭州市中心城区的多时相TM／ETM＋遥感影像为数据源，采用建设用地扩张强度、空间自相关方法等，分析了杭州市1991～2010年间城市扩张的时空特征，并探讨其扩张的空间模式及其演化．结果表明：（1）杭州市城区快速扩展，各街道一乡镇扩张程度存在明显差异；（2）杭州城市扩张的“热点”方位变化大致为：城北城西多方位一城东，其变迁规律与杭州城市扩张模式的总体变化规律一致；（3）杭州市城市扩张的空间模式主要有边缘式、填充式、自发式和线性轴状，且随城市演化过程总体遵循以下轨迹：首先，主城表现为边缘式为主、填充式为辅的扩张；其次，外围自发式的扩张形成了副城；接下来主副城都表现为从填充为主、边缘为辅的扩张转变为边缘为主、填充为辅的扩张；而线性轴状扩张是沿交通线发展并贯穿整个城市空间的演化过程．The economic growth and urbanization development of Hangzhou have been accelerated significantly and considerably by China＇s rapid urbanization and industrialization after the economic reformation in the late 1980s. The spatialtemporal characteristics and spatial patterns of urban expansion in Hangzhou from 1991 to 2010 were studied, which characterized by its typical peculiarity of the south lower reaches of the Yangtze River with street town （a sub-district or sub county administrative unit） as the spatial unit for our investigation and with the methods of Coil struction I.and Expansion Intensity, .Spatial Autocorrelation Analysis, and with the data of the existing land use classification maps （1991, 2000, 2005） and TM/ETM＋ remote sensing images （1995, 2010）, etc. The results in- dicated that： （1） the urban area outspreaded fleetly, while the development level differed in various streets （towns）. （2） the ＂hotspots＂ of urban expansion in Hangzhou was changed roughly in the way： north-west-multiori- entation-east. （3） the expansion patterns of the whole city included： edged, infilling, spontaneous and linear axes, and they evolved with urban development in the way as follow： Edged prevailing ＆infilling subsidiary （center）, spontaneous to form new center, infillding prevailing ＆ edged-subsidiary （center ＆. subcenters）, edged prevailing ＆ infilling subsidiary （center ＆ subcenters）, moreover the linear axes generated along the transportation networks and existed in the whole process of urban expansion from 1991 to 2010.
