Urban expansion mapping and driving factor analysis of Ordos City during the period of 2000—2013 based on DMSP/OLS nighttime light data

Abstract
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. -
