摘要 城市化发展所带来的社会经济的剧烈变动,促使城乡地域土地利用的根本性变革,并由此引发农村和城市协调发展等问题。城市化的过程也是一种土地利用的变动过程。伴随着城市化,土地利用问题日益成为影响城市化发展的关键。本研究选取西安市南郊为研究区,利用覆盖西安市的SPOT遥感影像,结合相关文献、资料,在解译的基础上获得1996年和2006年西安市南郊土地利用数据。通过分析对比可知,土地利用面积变化和类型改变对城郊经济结构以及社会活动都产生了巨大影响。为了实现城乡结合部的土地可持续利用,文中深入剖析了土地不可持续利用问题,进而提出了相应的对策建议。

Abstract:As the product of developing the social productivity to a certain degree, urbanization is closely related to industialization and modernization. It is a sign of social progress and the crystal of human civilization. At present, China is vigorously pushing forward the development of urbanization everywhere. The development of urbanization will be able to bring abront great changes of social economy, and have an effect on the ultimate alteration of landuse in the urban and rural regions, resulting in a series of issues such as the harmonions development in urban and rural regions. The course of urbanization is a kind of the process of landuse change. With the acceleration of urbanization, land-use problems become more and more serious. Using the SPOT image covered Xi'an city and relevant documentation and data, this paper selects the southern outskirts as research area, refers the national land use classification method, and acquires the land-use data of the southern outskirts in 1996 and 2006 by interpreting the image and vectorizing the Xi'an city map of corresponding years. With the spatial overlaying analysis of GIS, the paper quantitatively analyzes land-use change from 1996 to 2006 in research area, and subsequently uses the intensity index of urban construction land expansion with Quantitative Analysis. By analyse and comparison, this paper draws the conclusion that the area change and type change of land-use have the great effect on the economic structure and social activity in the outskirts. In 1996, arable land and residential land in the sourthern outskirts in Xi'an are respectively 67.02 percent and 16.85 percent. In 2006, arable land and public facilities in the sourthern outskirts in Xi'an are respectively 46.33 percent and 28.89 percent. The data indicates that arable land is decreasing with the development of urbanazition.
