基于GIS的侯马市建筑密度空间分布特征研究

An Analysis on Site Coverage Spatial Distribution Pattern Based on GIS in Houma City

建筑密度是研究城市空间结构的一个重要指标.本文利用GIS软件的空间分析功能,采用区域分割法和缓冲分析法对侯马市的建筑密度进行了分析.扇形分区分析结果表明:地理位置优越的东部和西部地区建筑密度较高,而南部由于受地形的影响建筑密度较低.缓冲区分析结果表明:建成区中心部分建筑密度最高,随着离市中心距离的增大,建筑密度逐渐降低.侯马市建筑密度的空间分布受到了地形、交通和经济发展状况等多种因素的影响.

Site coverage is an important index for studying spatial distribution pattern of the city. With the spatial analysis functions of GIS software, sector and buffer analysis methods are used to finding possible spatial distribution rules in Houma City. The resuhs of sector analysis show that the site coverage in such superior geographical condition areas as east and west is higher, and site coverage of south area is lower because of bad terrain. The results of buffer analysis irdicate that the density of city center is the highest and have a negative relation with the augment of distance. The site coverage spatial distribution is influenced by various factors, such as terrain, traffic and economic development.
