城市化进程中西安市土地利用变化研究

西安市土地利用处于发展期,也处于调整期。结合对西安市城市化发展的分析,通过引入"城市化下的边际城镇用地扩张量"指标,建立线性回归模型,研究了西安市城市化进程与土地利用变化之间的相关性得出结论:西安市城市化下的边际城镇用地扩张量总体是一个增大的过程。这说明西安市城镇居民点、工矿用地及交通用地面积扩张的过程比城市化率增大的过程要快,土地资源的缺乏已严重阻碍并将继续制约西安市未来的城市化进程。据此,就协调城市化与土地可持续利用之间的相互关系提出了几点政策建议。

Study on Land Use Change of Xi'an during Process of Urbanization

The land-use of Xi'an is in the duration of development and adjusting.After that,by bringing an index and setting up a regression equation,the paper studies on the correlation between land use change and urbanization of Xi'an City on the ground of urbanization.The result shows that the index is increasing,which elucidates that the speed expansion of population centre,industrial and mining field and traffic field is quicker than the urbanization.As a result,the lack of land resource has severely retarded the urbanization and will impact it in the future.At last,some suggestions are proposed.
