Dynamic Study on Landuse Based on Rs Images in the Western Region of Jinan

Three-phase RS images, including the TM data of 1987 and 1996, the CBERS data of 2010, were selected to classify the study area by using supervised classification of the maximum likelihood method. The study area was divided into four classes including agricultural land, construction land, water and unused land. Then the post-classification comparison method was used to monitor the change of land use dynamically in order to extract the quantitative and spatial change information from 1987 to 2010. The results show that: with the development of economic and the increase of population in twenty-three years, the construction of the new West Railway Station of Jinan made all kinds of land use change more obviously. Firstly, the area of agricultural land and the unused land decreased gradually which transformed into construction land. Secondly, the proportion of urban construction land has been increasing during twenty-three years.
