摘要:

基于1988年TM影像、2002年ETM影像和2007年TM影像提取了西安市主城区和远郊区城镇建设用地信息,利用GIS技术对三期城镇建设用地进行了叠加得到西安市城镇扩展数据。利用主要道路交通图和行政边界图对扩展数据进行裁切,得到了西安市绕城高速内和远郊区的城镇扩展信息。运用扩展强度指数、城镇建设用地相对变化率和分形维数等模型对西安市的城镇扩展进行了分析研究。研究结果表明,研究区内的城镇建设用地面积从1988年的151 796 493.8 m2增加到2007年的365 180 608.0 m2,总体扩展了2.4倍。其中主城区的扩展主要集中在二环与绕城高速之间,二环内的城镇建设用地面积扩展速度相对较慢;西安市的3个远郊区中长安区扩展倍数最大,在1988~2007年扩展了7.39倍,其次为临潼区和阎良区;1988~2002年西安市的主城区和远郊区的分形维数都呈增加的趋势,城市边缘形态趋于复杂,而2002~2007年分形维数呈减少的趋势。西安市远郊区的城镇建设用地相对变化率高于主城区,未来城市发展的格局逐渐呈现为主城区城镇扩展速度的相对放缓和远郊区的规模不断增大的趋势。

Abstract:

Based on the Landsat TM/ETM images of Xi′an in 1988,2002 and 2007,the built-up land information were extracted,the built-up land map overlaying using GIS technology,as a result ,the sprawl information and data were obtained.The sprawl data were subset by the maining road traffic map and administrative boundaty,sprawl information of inner express way around city and the district of outside suburb were obtained.This paper analyzed the city sprawl by using growth intensity index,relatively built-up land transformation rates and fractal dimension model.The research results indicates that the area of built-up land increased from 151 796 493.8m2 to 365 180 608.0m2 during the period from 1988 to 2007,which increased for 2.4 times;the sprawl of urban district concentrate on the area between the second circular road and express way around city,meanwhile the built-up land area inner the second circular road increased more slowly.The sprawl times of Chang′an district among the outside suburb districts is greatest,which expanded 7.39 times for its area from 1988 to 2007.The Lintong district and Yanliang district are lower.The fractal dimension of urban district and outside suburb district in Xi′an tend to increased in the period of 1988 to 2002,the edge of city tend to be conplexity,however,the fractal dimension decreased in the period of 2002 to 2007.The relatively built-up land transformation rates in outside suburb district is higher than urban district.The future develop trend of Xi′an is that the sprawl in urban district to be slowly while outside suburb district scale will be increase.

Key words: GIS technology    Built-up land sprawl    Urban district and outside suburb district    Xi′an
