为了探索我国土地城镇化规律,基于2000--2012年省级数据,运用统计分析法研究了我国土地城镇化的时空特征及机理。研究表明,全国和各个省份的城镇建成区与土地城镇化水平均有大幅增长,但省际差异较大,空间格局上呈现出显著的峰值效应;土地城镇化快于人口城镇化,且省际差异明显;相对于土地城镇化水平空间格局而言,省级城市建成区规模空间格局与GDP的空间格局更为相似;经济增长、土地财政、用地指标、土地资源禀赋及现行土地征收制度是造成这种变化的主要影响因素。
Based on the provincial data from 2000 to 2012, this paper analyzed the spatio-temporal characteristic and influence mechanism of land urbanization. The result indicates that : ( 1 ) the urban build-up area scale and land urbanization level were increased significantly, however, the difference among provinces were obvious, provin- cial spatial pattern of build-up area and land urbanization level showing the remarkable peak effect ; (2) land urbani- zation was faster than population urbanization, but the difference among provinces were obvious ; (3) relative to the spatial pattern of land urbanization level, spatial pattern of provincial build-up area was more similar to the spatial pattern of GDP; (4) economic growth, land revenue, land target, land resources and the current land expropriation system were the main factors causing the change.
