摘　　要：在地理信息系统技术的支持下，对多种来源的图件进行扫描、修正、拼接、配准、矢量化等预处理后，新采用嵌套网格法统一提取各个时段广州市建成区边界，重建并获取了1907、1928和1968年广州建成区土地利用／覆被信息．在此基础上，结合其它历史文献，分析和总结了1907～1968年广州建成区土地利用／覆被变化的时空特征．结果表明：1907～1968年，广州建成区的土地利用类型构成均以居民点及工矿用地、水域和交通用地为主，土地利用类型面积变化的速率是具有波动性的．1907～1928年，交通用地面积增加幅度最大；1928～1968年，居民点及工矿用地和未利用地增幅最为显著．60年间，随着建成区面积扩大，河流长度与水域面积在不断增大，但珠江主干的平均宽度却逐渐降低．After pre -treatments with the maps from multiple sources by using geographic information system, the authors apply a new method to extract the urban boundary information and reconstructs the land using map of Guangzhou in 1907,1928 and 1968. Combining the materials in other literatures, it analyzes and summarizes the space - time features of land use/cover change in Guangzhou urban built - up area from 1907 to 1968. The results show that during 1907 to 1968, the main land used types in Guangzhou urban were the residential area, the industrial area, the water area, and the traffic land. The area change rate of land used type are fluctuate. During 1907 to 1928, the area of traffic land increased most. The area of the residential area, the industrial area and unutilized land increased dramatically from 1928 to 1968. During the 60 years, with the increasing of the built -up area, the river＇s length and the water area increased constantly, but the average width of the trunk stream of the Pearl River were gradually decreased.
