回顾中国最近20年的快速城镇化进程,土地资源的供给性短缺和需求剧增的矛盾日趋尖锐,土地城镇化快于人口城镇化已经成为政府和专家的共识。以山东省为例,基于区域结构、用地结构、城市规模结构的视角,运用异速生长模型,分析2000-2013年期间城市建设用地扩张的人口绩效。结果表明:①从空间结构看,山东省土地城镇化总体快于人口城镇化,并且鲁西北、鲁西南和半岛中部地区的城市用地人口绩效高于中部和胶东半岛东部地区。②从用地结构看,不同类型建设用地之间存在显著差异性,居住用地、工业用地和绿地扩张所承载的人口绩效较低,仓储用地扩张的人口绩效偏高;③从城市规模结构看,人口规模在20万以下的城市建设用地扩张的人口绩效最高,20—50万规模城市最低,50万以上规模城市居中,且呈逐渐降低的态势。
Reviewing the development of rapid urbanization during the last two decades in China, the contra- diction between the shortage of land supply and the high demand for urbanization has been sharp. Govem- ments and experts have reached a consensus that land urbanization is faster than population urbanization. However, this is just a superficial phenomenon from the perspective of urban system and its differences should be analyzed from, the structural level. Taking Shandong Province as an example, from the perspec- tive of regional structure, land use structure and the city scale structure, the population performance of expansion of construction land between 2000 and 2013 is analyzed based on allometric mode. The results indicate that: (1) From the perspective of spatial, land urbanization is faster than population urbanization in the whole province, and population performance of urban land is higher in northwest of Shandong, southwest of Shan- dong and peninsula area. The central and coastal areas become lower. (2) From the perspective of land use structure, there are differences among types of construction land in different cities. Population performance of urban land is higher in the residential land, industrial land and green land, and the storage land is lower. (3) From the perspective of city scale structure, the city with a population of less than 200,000, the urban popula- tion performance is the highest while the city with a population of 200,000-500,000 is lowest. The city with a population beyond 500,000 shows a decreasing trend.
