摘　　要：我国已进入快速城市化时期,城市用地迅速增长,研究我国城市用地规模分布变化规律有助于在城市化进程中合理配置城市用地,促进城市体系协调发展.选择2000年~2012年我国地级及以上城市的建成区面积数据,利用位序-规模法则结合分形理论,研究我国城市用地规模分布的变化趋势并分析不同区域城市用地规模分布变化的差异性.研究结果表明：（1）以建成区面积衡量城市规模,我国城市规模分布符合位序-规模法则;（2）城市规模的位序-规模对数曲线呈平行向前推进趋势,城市用地规模总量增加,但城市用地规模分布Zipf指数呈上升趋势,城市用地规模分布的均衡度下降;（3）按建成区面积分类,超大、大城市的城市用地增长速度快于中小城市;（4）不同区域城市用地规模分布变化特征反映出差异性：4大区域中东部地区城市用地规模Zipf指数始终最接近理想值1,表明东部地区高中低位次城市用地发展较为协调,东北地区以及西部地区城市用地规模分布趋向于集中,高位次城市用地扩张明显快于中低位次城市,中部地区城市用地规模分布较为分散,但近几年高位次城市用地规模扩张趋势明显增加.China has faced a period of rapid urbanization,and also witnessed a rapid growth of urban land.The study on the changing rules of city size distribution of China is conducive to the rational allocation of urban land and the coordinated development of urban system in the urbanization process.On the basis of the data on the built-up areas of Chinas cities in prefecture-level and above from 2000 to 2012,this paper studies the change trend of the city size distribution in China and analyzes the regional differences in the changes by adopting the rank-size rule and fractal theory.The results show that：1）the built-up-area-measured city size distribution of China is consistent with the rank-size law;2）the logarithmic rank-size curves of the city size parallel and move outward,indicating that the total amount of urban land have increased,but the Zipfindex of city size distribution has increased over time,indicating that the equilibrium degree of city size distribution have declined;3）the growth rates of the urban land in the cities with built-up areas more than 500km^2 and between 200-500km^2 have been greater than those in the cities with built-up areas between 50~200km^2 and less than 50km^2;4）The change of the city size distribution in different regions is different from each other,and among the four regions,the Zipfindex of city size in the east region is always closest to the ideal value of 1,suggesting that the development of urban land in high,medium and low ranks in the east region is relatively coordinated,while the city size distribution in the northeast and west regions has a tend of being concentrated,with the high-rank cities having faster land expansion than the medium and low-rank cities,and the city size distribution in the central region is relatively scattered,but in recent years,the high-rank cities have expanded significantly.
