Nighttime light data have been widely used for mapping urban land. Previous application of the TM-assisted thresholding method mainly determined threshold of the nighttime light data in each city, which is not suitable for the study at a large scale due to its low processing efficiency and high data acquisition cost. In this paper, based on the TM-assisted thresholding method, the authors put forward the partition idea to extract the urban area using the DMSP/OLS nighttime light data. China was divided into 7 major regions based on economic partition and then TM-assisted thresholding method was employed to extract urban land areas. Finally, applying real urban land use pixels judgment, the authors obtained China’s urban land information of the years 1992, 1995 and 2000. A comparison with the previous method shows that the performance of the method based on partition idea is more efficient and can ensure overall accuracy.
