基于DMSP/OLS夜间灯光影像的2000—2013年鄂尔多斯市城市扩张遥感制图与驱动因子分析
|
摘要
内蒙古自治区鄂尔多斯市在过去十几a中经历了经济的飞速发展与城市的快速扩张,目前却面临着经济发展的停滞与城市转型。对鄂尔多斯市城市扩张及其驱动因子在时间及空间尺度上的分析,可为鄂尔多斯市的城镇化发展规划提供参考信息。利用DMSP/OLS夜间灯光(nighttime light,NTL)遥感数据,并结合Landsat影像数据,对鄂尔多斯市2000—2013年间城市扩张进行遥感制图和信息提取;应用基于稳定映射点NTL影像间辐射校正方法和支持向量机(support vector machine,SVM)算法,并结合阈值法进行数据校正和建成区面积提取。经分析发现鄂尔多斯市分3个阶段扩张,并提出应用组合分析的方式对城市扩张驱动因子进行定量分析。
In the past decade,Ordos City of Inner Mongolia experienced rapid development of economy and rapid urban expansion,and now it is facing the stagnation of economic development and urban transformation. Urban expansion mapping and driving factor analysis at temporal and spatial scales could provide valuable information for the urbanization development planning of Ordos. Using the DMSP/OLS nighttime light( NTL) data combined with Landsat image,the authors compiled urban expansion maps for the period from 2000 to 2013. The build-up areas were extracted using a radiometric correction method based on the stable point NTLs,support vector machine( SVM) classification and thresholding techniques. The statistical analysis results show that the expansion of Ordos City can be mainly divided into three stages,and the driving factors of urban expansion could be quantitatively analyzed using the portfolio analysis method.
