摘要
文章选择2000-2011年环渤海44个城市建成区面积资料,利用位序—规模法则和分形理论分析了城市规模分布及其演变规律,得出:以建成区面积表征的城市规模符合位序—规模法则,拟合曲线的判定系数都在0.96以上;城市建成区面积规模分布的均衡度相对稳定,建成区面积总量将不断增加;城市建成区面积位序—规模曲线有平行向前推进的特点,为预测环渤海经济圈城市未来建成区面积规模提供了很好的依据;根据位序—规模曲线的形态,这些城市按建成区面积可分为2大类5小类。
This essay, based on built-up areas of 44 cities in Bohai economic zone from 2000 to 2011, analyses city-size distribution and its evolutionary rules through rank-size rule and fractal theory. It shows that city size featured by built-up area conforms to the rule of rank size and the determination coefficient of the fitted curve is above 0. 96; the distribution of built-up area is increasing; the rank-size line of city buil basis for a forecast of Bohai economic zone＇s built-up built-up area is well balanced and the total amount of t-up area reveals a forward trend, which provides a area in the future; according to the rank-size curve, city built-up area can be divided into two main and five small classifications.
