摘要
运用分形几何学理论和数理统计方法,在遥感技术与G IS技术的支持下,利用2002-2004年闽台A STER影像数据经过几何校正等处理后提取建设用地斑块的面积和周长,对闽台建设用地分布的空间特征进行分析.研究结果表明,闽台建设用地斑块存在明显的统计意义上的自相似性,具有分形结构特征,其空间形态受自然和人文两方面因素特别是地形和交通的影响十分显著.同时台湾建设用地的平均斑块面积、分维值和规模大的斑块比重均高于福建,反映了闽台两地建设用地空间特征的区域差异.
Based on fractal geometry, RS and GIS technology, describes an algorithm for fractal dimension of spatial structure and pattern of built-up land in Fujian and Taiwan. Remote sensing techniques provide the necessary data rapidly and periodically for the spatial characteristics study. The study area including Fujian province and Taiwan province is clip from ASTER images in 2002-2004 after geometric correction based on the topographic map. Based on GIS, the area and perimeter of built-up land patches are distilled. The result indicates that built-up land patch has statistical self-similarity, and the spatial feature of built-up land is mainly impacted by the local terrain and traffic condition. According the fractal dimension analyse, it points out some different character of the spatial structure and pattern of built-up land between Fujian and Taiwan.
