Abstract

The aim of this study is to analyse the urban land use changes of the central part of Ulaanbaatar city, Mongolia using advanced spatial methods. For the study, the changes that occurred before 1990 are compared with the changes that occurred after 1990 and the socio-economic reasons for the changes are described. For the development of the primary digital database, a large scale topographic map and historical description of the land use elements are used. To update the database and extract the reliable urban land use information, very high resolution panchromatic and multispectral Quickbird images of 2012 are fused. To generate land use information from the fused images, a visual interpretation is applied. Overall, the analysis demonstrates that during the market economy the central part of the capital city urbanised very rapidly and became very dense.

基于空间技术的蒙古城市土地利用变化研究
本文采用先进的空间方法,对蒙古乌兰巴托市中心城区的土地利用变化进行了分析。在这项研究中,将1990年之前发生的变化与1990年之后发生的变化进行了比较,并描述了这些变化的社会经济原因。在初级数字数据库的开发中,使用了大比例尺地形图和土地利用要素的历史描述。为了更新数据库,提取可靠的城市土地利用信息,将2012年高分辨率全色和多光谱Quickbird影像进行融合。为了从融合的图像中生成土地利用信息,应用了视觉解译。总体而言,分析表明,在市场经济时期,首都中心城区城市化速度非常快,人口密度很高。
