| 摘 要： | 以江苏省1996～2008年城市非农业人口和建成区土地面积为主要数据，借助分形地理学中的城市位序一规模分布法则和异速生长定律及其广义分形性质，对全省城市规模分布演化规律、结构容量和城市人口-面积异速生长标度指数、退化关系进行探讨。结果表明：全省城市体系发育较为健全，规模序列结构正处于集中向分散过渡的时期，大中城市成为城...

| Abstract: | With the acceleration of urbanization,the evolution of the urban systems tends to be more complicated.Working on a major database of regional non-agricultural population,built-up land acreage of cities and counties in Jiangsu over 1996-2008,the study uses methods of rank-size rule,law of allometric growth and its multi-fractal property to analyze the fractal feature of city-size distribution,structural capacity,index scale and degeneration of population-area allometric growth.The results indicate that urban system of Jiangsu Province is now in good gear,its rank-size structure is experiencing a mutation from centralization to decentralization,large and medium-sized cities are the main supporting space for urbanization process.The allometric growth relationship between land and population is in trends of degeneration at provincial level,which turns negative to positive after 2001.Scale factors of allometric growth of Nanjing,Suzhou and Xuzhou have a mark significantly higher than those of other cities,indicating a faster spatial expansion compared with population growth in these cities.In the meantime,relationship between land and population needs further discussion.Complex patterns resulting from evolution of the urban system make higher demands for developing a new-type urbanization with its own characteristics in Jiangsu. |
