摘要
从ASTER卫星影像中提取城镇建成区空间信息,采用城镇用地规模代替人口规模运用位序-规模法则和分形理论对闽台两地城镇土地利用规模的变化规律进行对比分析。结果表明:(1)位序-规模法则能很好地描述福建省和台湾省城镇用地规模分布特征。(2)相比于全国和其他区域的研究而言,闽台两地城镇体系较简单、总体规模小,而且主要集聚分布在闽东南地区及台湾西部地区。(3)正处于工业化和城市化加速发展阶段的福建省,未来城镇用地规模特别是中心城市规模将会迅速增长。
This paper studied the city-size distribution between Fujian Province and Taiwan Province based on remote sensing. The built-up area theme information was extracted from ASTER images in 2004. We employed the built-up area （rather than population） to analyse the city size distribution using the rank-size law. Then, the rank- size curves were explained by using theory of fraetal and the results, include the following several aspects. Firstly, the city size distribution in terms of urban built-up area perfectly accorded with rank-size rule, and the coefficient of determination （ R 2 ） were both more than 0.95. Secondly, the urban system in Fujian Province and Taiwan Prov- ince was simple and in small scale, and gathered distribute in south-eastern coastal areas of Fujian Province and western areas of Taiwan Province. Lastly, the city size would increase rapidly in Fujian in future, because Fujian was experiencing rapid industrialization and urbanization processes.
