摘要

选择西安市作为研究对象

采用1996—2005年的统计数据

研究了快速城市化条件下的西安市土地利用变化情况。首先从变化幅度、变化速度和变化程度3个不同的角度分析西安市的土地利用变化

发现10 a内

西安市的耕地、牧草地、未利用土地面积均不断减少

而园地、林地、居民点及工矿用地、交通用地

水域面积分别呈增长态势。其中

耕地面积递减速度最快

牧草地次之

接着为未利用土地

而交通用地为增长最快的土地利用类型

居民点及工矿用地次之

依次为园地、林地和水域。因此西安市土地利用处于发展期

也处于调整期。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。结果显示

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。最后提出了协调城市化与土地可持续利用相互关系的政策建议。

Abstract

Taking Xi’ an City as an example and using statistical data from 1996 to 2005

the landuse change of Xi’ an City during its accelerated urbanization is studied.Firstly

the landuse change of the city is analyzed from different stand-points.The area of cultivated land during the 10 years

as well as that of pasture and idle land

is found to decrease.Moreover

the areas of garden

forest land

population centre

industrial and mining field

traffic field

and water body increase.Therefore

the landuse of the city is in the duration of development and adjustment.After that

by bringing in an index and setting up a regression equation

the correlation between landuse change and urbanization of the city is studied on the ground of analyzing the urbanization.The analysis indicates an increased index

which elucidates that the expansion of population centre

industrial and mining field

and traffic field is quicker than the urbanization.As a result

the lack of land resources has severely retarded the urbanization and will impede it in the future.At last

some suggestions are proposed.
