福州市土地利用空间结构和形态变化分析

为了增进对土地利用空间结构和形态变化的理解，以分形理论为指导，在遥感和GIS技术的支持下，对福州市土地利用空间结构和形态变化进行了分析。首先对来自遥感影像建立的福州市土地利用空间数据库进行提取，然后运用土地利用空间格局的分形模型，计算了福州市1988年和2004年两个时期各个土地类型的分形维数和稳定性指数，对福州市土地利用结构和形态演变进行了定量分析。为区域土地合理利用以及优化配置提供参考依据。

Spatial structure and form change analysis of land use in Fuzhou City

The theory of fractal is a new tool for land use spatial structure study,with the techniques of RS(Remote Sensing) and GIS(Geographic Information Systems) supporting,this paper analyses the spatial structure and form change of land use in Fuzhou City.Firstly,supported by RS and GIS the land use classification information is extracted from the Landset TM and ASTER images of Fuzhou City of 1988's and 2004's,and spatial database of land use is built.Then in order to improve the understanding about the land use change in Fuzhou City,the fractal and the stability indexes of different land types are calculated based on the theory of fractal model.The results show that some of land use change characteristics are complication,on the other hand,some of land use change characteristics are simplification.And some pieces of advice on land use utilization and optimized configure is given at last.
