广州-佛山都市区城乡聚落时空演变

Study on Settlement Development of Guang-Fu Metropolis Based on Spatial Information Technology

分析了广州 -佛山都市区城乡聚落时空演变的区域历史背景。利用地形图与卫星遥感影像数据 ,采用定性与定量相结合的数据挖掘方法 ,在空间信息技术的支持下 ,探讨了广州 -佛山都市区城乡聚落近一个世纪的时空演变规律 ;初步总结出聚落演变时空信息图谱的双核心、生命节律、跳跃 -填充 (Jum p- Fill)、TOD模式等特征 ,并进一步研究了其方向与应用前景。

This paper analysed the region development history of Guang Fu met ropolis. We studied on the settlements development of Guang Fu metropolis a rea during 20th century using data mining methods based GIS and RS technology,data sources from SPOT,TM imageries and topography base maps(1:50000) were used. Four features of double core,life rhythm,J F(Jump Fill),TOD are co ncluded from the spatio temporal information TUPU of settlement in Guang Fu metropolis. Some problems of spatio temporal information TUPU future study are discussed.
