【摘要】：土地是人类生存与发展的资源基础,随着城市的发展,对土地的需求量越来越大,由于人口的增加和对土地的不合理利用,出现土地生态环境的恶化,供需矛盾加剧,阻碍土地可持续利用等问题。从而土地利用的动态变化越来越被认为是一个关键而迫切的研究课题。土地利用变化的动态监测以遥感信息作为数据源,具有周期性、广域性、经济性等特点,再结合地面辅助资料,借助计算机图像处理技术,对土地利用状况及其动态变化进行全面系统地评估和分析。适时了解土地利用现状和结构变化,对于促进土地合理利用,实现土地可持续发展具有重要意义。而城市群作为城市化发展的主要形态,是实现资源集约利用的有效途径之一,将在新型城镇化发展建设中发挥着重要的作用。乌鲁木齐城市群是一个正在形成中的干旱区绿洲城市群,乌鲁木齐城市群在经济持续发展的同时,城市空间也在不断的发生变化。随着城市扩展速度的加快、交通及网络的扩张,该地区城镇体系的空间分布格局以及土地利用方式等都发生了很大的变化。本文以乌鲁木齐城市群(乌鲁木齐市、昌吉市、阜康市、五家渠市、石河子)作为主要研究对象,通过解译2000年、2006年、2013年乌鲁木齐城市群中各城市的遥感影像,重点研究2000—2013年乌鲁木齐城市群的土地利用变化状况,并对乌鲁木齐城市群土地利用动态变化进行综合分析。结果如下:(1)从乌鲁木齐城市群的土地利用类型面积来看,2000年、2006年和2013年这三年中城市未利用地比重较大,这是由乌鲁木齐城市群所处的地形决定的。乌鲁木齐城市群中的乌鲁木齐市由于受地形的限制,未利用地面积增速缓慢,而昌吉市、阜康市、五家渠市北部大部分在古尔班通古特沙漠,城市建设面积小,但随着社会、经济、人口的快速发展,城市建设用地面积在不断的增大,未利用地面积也在不断的减少。(2)乌鲁木齐城市群2000—2013年之间的土地利用变化比较大,从结果及变化幅度来看,城市建设用地的变化较为突出。而在城市建设用地变化中居住用地、工业用地以及公共设施用地所占比重有上升趋势。(3)乌鲁木齐城市群的土地利用变化主要受自然因素和人文因素的共同影响。概括起来主要有以下几个方面:人口增长、经济发展及产业结构变化;此外,政策因素也是影响城市土地利用变化的一个重要因素。
[Abstract]:Land is the resource base of human existence and development. With the development of city, the demand for land is increasing. Because of the increase of population and unreasonable use of land, the deterioration of ecological environment of land and the intensification of contradiction between supply and demand. Obstacles to sustainable land use and other issues. Therefore, the dynamic change of land use is more and more regarded as a key and urgent research topic. In the dynamic monitoring of land use change, remote sensing information is used as data source, which has the characteristics of periodicity, wide area, economy and so on. Land use and its dynamic changes are comprehensively and systematically assessed and analyzed. It is of great significance to understand the present situation and structural change of land use in time to promote the rational use of land and to realize the sustainable development of land. As the main form of urbanization, urban agglomeration is one of the effective ways to realize intensive utilization of resources, which will play an important role in the development of new urbanization. Urumqi urban agglomeration is an oasis urban agglomeration in arid area. The urban space of Urumqi urban agglomeration is changing while the economy is developing continuously. With the acceleration of urban expansion and the expansion of traffic and network, the spatial distribution pattern and land use pattern of urban system in this area have changed greatly. In this paper, Urumqi urban agglomeration (Urumqi, Changji, Fukang, Wujiaqu, Shihezi) as the main research object, by interpreting the 2000, 2006, 2013 Urumqi urban agglomeration remote sensing images, This paper focuses on the land use change of Urumqi urban agglomeration from 2000 to 2013, and makes a comprehensive analysis on the land use dynamic change of Urumqi urban agglomeration. The results are as follows: (1) according to the land use area of Urumqi urban agglomeration, the proportion of unused land in 2000, 2006 and 2013 is large, which is determined by the topography of Urumqi urban agglomeration. Urumqi, in the Urumqi urban agglomeration, grows slowly due to the limitation of topography, while Changji City, Fukang City, and Wujiaku City are mostly in the Guerbantungote Desert. The urban construction area is small, but with the society, With the rapid development of economy and population, the area of urban construction land is increasing, and the area of unused land is also decreasing. (2) the land use change of Urumqi urban agglomeration from 2000 to 2013 is relatively large. The change of urban construction land is more prominent. However, the proportion of residential land, industrial land and public facilities land has an upward trend in the change of urban construction land. (3) the land use change of Urumqi urban agglomeration is mainly influenced by natural and human factors. In summary, there are the following aspects: population growth, economic development and industrial structure change; in addition, policy factors are also an important factor affecting urban land use change.
