摘　　要：选择2004年建成投用的广州大学城为例,以2005年和2009年SPOT5高分辨率遥感影像数据作为主要数据源,运用RS、GIS技术对大学城及周边地区的土地利用类型进行分类,重点分析广州大学城自建成以来建成区、裸地、绿地的土地利用/覆被变化情况,分析了大学城中心湖区7km范围内的土地利用变化情况。结果表明,大学城建成区中的教学楼、实验楼、生活楼、行政楼、道路等最早建设完成,而商服、住宅、文体设施等在2005年后才陆续修建。至2009年,除部分新批建住宅用地外,其余用地大部分已建设完成。建成区和绿地面积增加迅速,裸地持续呈动态变化,以减少的趋势为主;施工建设的区域明显减少。受大学城建设的影响,大学城附近的用地沿交通线轴向变化明显。The Higher Education Mega Center （HEMC） in Guangzhou was built and put into service in 2004. In this paper the land use changes in the HEMC and its surrounding areas is studied with high-resolution remote sensing data SPOT5 from 2005 to 2009 as the main data sources, while RS and GIS technologies are used to classify the land use types. More attention is paid to the land use changes of the built-up areas, bare land and green land as well as the changes of vegetation cover, and further analysis on land use changes of the areas around the central lake within 7 km is conducted. The results show that, in the built-up areas of the HEMC, teaching, laboratory, dormitory and administrative buildings and the roads had been completed in 2005, then facilities of business services, housing and sports etc. were built in succession. Until 2009, in addition to that for some new approved residential buildings, most of the remaining land had already been developed. Built-up areas and green areas increased rapidly, while the bare land continued to decline. Meanwhile, the areas under construction significantly reduced. Moreover, obvious changes of land use have taken place along the traffic axial lines around HEMC.
