Analysis of Spatial Difference in Regional Urban Land Intensive Utilization:A Case Study of Jilin Province

Taking nine cities of the Jilin Province as sample,this paper tries to explore the comprehensive evaluation system of regional urban land intensive utilization from the aspects of land use intensity,land use degree,land use benefit,and eco-envircnmental intensiveness.Using global principal components analysis of SPSS 13.0,the lever of urban land intensive utilization from 2000 to 2009 was evaluated.Then based on the scores of all factors,its variation characteristics in space was summarized using cluster analysis. The results showed the level of urban land intensive utilization of Jilin Province improved from 2000 to 2009.The regional differences of urban land intensive utilization were obvious,but its trend of change was reducing instablely.The urban land intensive utilization displays as a core in space,the level of Changchun's land intensive utilization is much higher than that of other cities.The spatial difference also exists as that of cities in central of Jilin is the highest,that of cities in western part is the lowest and the eastern cities having the medium level.According to the spatial difference,this paper analyses the reasons from the aspects of regional environment,scales of cities,economic growth and industrial structure.Based on the analysis,it can conclude that there are many factors affecting the urban land intensive utilization of Jilin Province,the difference of development environment is the basic reason,economic development level is the most important external factor affecting the level of urban land intensive use.The level of urban land intensive utilization is higher in developed areas,like Changchun and Songyuan higher than other cities. Finally,this paper proposes that Jilin Province should excavate the potential of urban land intensive utilization,and avoid the expansion of urban land rapidly.So in the future,Jilin Province should make full use of urban land efficiently and reasonably,and take the way of sustainable development.
