摘要 以乌鲁木齐都市圈为研究区域,在分析遥感信息的基础上,探讨干旱区绿洲城镇群的空间发展过程与未来的空间发展模式。首先,对1989年的TM和2002年的ETM+影像进行解译,提取研究区的主要用地信息。然后,基于解译信息分析农业用地、城镇用地与农村居民点的变化情况,揭示绿洲城镇群的动态演化过程。再次,探讨了研究区发展过程中出现的行政界限束缚城镇发展、城镇间无序化的分散发展以及绿洲基底景观的破脆性增强等空间问题。最后,在分析动态变化的基础上,针对现有的空间发展问题,提出了一些空间发展构想,以期对本区今后空间的合理发展提供借鉴。

Abstract:Urumqi metropolitan is an oasis Urban Agglomerations in arid region. It plays an important role in Xinjiang. Recently, the government pays more attention to Urumqi metropolitan and the economic co-development is undergoing. Therefore, it is necessary to study on the issues on space of the region today. Based on remote information, this paper analyzes the developmental process of oasis Urban Agglomerations, Urumqi metropolitan, and discusses the spatial developmental modes in future. Firstly, we get main land cover information from remote image of TM (1989) and ETM+(2002) which have spatial resolution of 28.5 meter. According to the characteristic of the study area, 8 types of land use are classified in this paper. They are urban and town land, country residential land, road land, agriculture land, natural vegetation, water, desert and other bare land. Then, the area changes of these lands are analyzed by the data from remote information. In the process of the oasis development, the agricultural land has Increased obviously. With the growth of economy and population, the urban land and country residential land are also increasing clearly. Contrastively, the bare land is decreasing because of the conversion to other kinds of land. Meanwhile, the natural vegetation, water, desert have little variety. The landscape index of main land is changing during the period. Thirdly, some problems appearing from the spatial development process of urban and town group are discussed. One is that administrative boundary restricts the urban process and the central urban, Urmqi, can not exert its radiate function in so limitative space. One is that the urban and town group developed disorderly in space. The other is the fractal of oasis landscape increased, especially the agricultural land and the country residential land. Finally, we put forward some modes of this area in spatial development to help oasis urban development sustainable. Co-development is the foundation for Urmqi Metropolitan to orderly development. Each urban and town in Urmqi Metropolitan should break the administrative restriction and take itself into the region to get all of them development harmoniously. Centralization and Separation in space is a better spacial pattern for Urmqi Metropolitan. Centralization means make the central urban become much stronger to guide the other towns around it. Separation means that each urban and town should be optimized to form reasonable special pattern. Re-adjust the function space in the area of Urmqi Metropolitan is a reasonable way to alleviate the burthen of central urban. In region scale, the industry, commerce and finance, agriculture function space can be adjusted according to the characteristic and potential of every urban and town. This can help us make our activity reasonable.
