中文摘要	本文研究分析唐山大地震后城市空间形态变化:利用多源多期遥感数据,通过建筑指数和植被指数相结合提取唐山市33年间10个时相建成区信息;采用质心变化、分形维数和紧凑度对形态进行分析,并探讨其变化原因。结果表明,1977年~2003年轮廓越来越复杂、从紧凑变为分散、扩张迅速;2003年~2010年扩张稳定性较高、越来越紧凑、边界变得简单;人口增长、经济发展和城市化进程促进了建成区的扩展,而塌陷积水区限制了其向南发展。; To analyze the changes of spatial morphology and causes in Tangshan City after earthquake, the information of 10built-up areas during 33years was extracted with Built-up Index and Vegetation Index based on the multi-source and multi-period remote sensing data in this paper.The morphology was analyzed by means of centroid changes,fractal dimension and compact ratio,and the causes of the morphology change were discussed.The result showed that the contour became more complex,from compact to dispersed and expanded outward rapidly during the years of 1977-2003;however,the stability of expanding outward became much higher and more compact than before,and the border became simple during the years of 2003-2010.The population growth,economic development and urbanization process promoted the expansion of the built-up areas,while subside seeper areas limited the development of urban built-up areas southward.
