摘要
选取1996年,2000—2003年山西省11个地级市建成区用地规模的资料,把运用在城市人口规模上的位序—规模法则,首位比,不平衡指数法移植到城市用地上,分析了山西省地级市建成区土地利用规模的变化规律,然后运用分形理论,阐释了位序—规模曲线。得出结论:(1)山西省地级市用地规模分布的均衡程度不断增强;(2)山西省地级市用地规模的总量不断增加;(3)对城市用地规模进行分类,发现小城市的数量在逐渐减少,中等城市的数量在逐渐增加;(4)首位城市太原市的用地规模已基本稳定,中等城市和小城市的用地规模将会扩大,其速度是前者大于后者。
This research analyzed changes in urban built -up area of 11 major cities in Shanxi province from 1996 to 2003. The rank- size law, the primacy index, the imbalance index method which were often employed in the study of cityg population size distribution were used. Then the rank - size curves were explained using the theory of fractal. The results included the following several aspects. Firstly, the city size distribution in terms of urban built - up area was gradually well developed in Shanxi. Secondly, the total amount of urban built - up area was increasing continuously. Thirdly, through classifying the urban built -up area of 11 major cities in Shanxi, we found that the amount of cities which size did not achieve 20km^2 was reducing continuously, while the amount of cities which size was between 20km^2 and 50km^2 was increasing continuously. Fourthly, the built - up area of Taiyuan was steady assumably, the rate of urban land expansion with cities which size was between 20km^2 and 50km^2 was faster than the rate of urban land expansion with cities which size did not achieve 20km^2.
