With the continuous urbanization, Land-use patterns are changing fast in the Wohushan region of Jinan. Four-phase RS images, including the TM data of 1987, 1996, 2006 and 2015 were selected to classify this area by using supervised classification of the maximum likelihood method. Detailed land-use types are collapsed into six categories, namely cultivated land, forest land, rural settlement land, water area, rage-grasses and road. Then the post-classification comparison method was used to monitor the change of land use dynamically in order to extract the change information from 1987 to 2015. Detailed analyses have revealed that great changes have taken place in the land use type of Jinan Wohushan region during 1987-2015. The area of agricultural land, forest land and rage-grasses decreased gradually which transformed into construction land. The agricultural land reduced 11.28km 2 and forest land reduced 7.72km 2 . At the same time, the area of rural settlement land has been increasing during twenty-eight years, which was 12.66km 2 in 1987 has increased to 29.88km 2 by 2015.The extent of road, which was 10.40km2 in 1987 has increased to 13.17km 2 by 2015.Transfer matrix analysis have revealed that the cultivated land is the main source of other land use types. The increase in residential areas mainly comes from farmland, forestland and ragegrasses. Introduction Significant land-cover changes have occurred in response to human activities since the last century [1-3]. Conversion of cropland into residential areas has risen due to economic and population growth. For such a complex urban system, how to control its expansion rate timely and accurately has become an urgent problem. Because traditional investigation was time and labor consuming, it was necessary to extract the landuse information based on remote sensing image [4-6]. Many scholars have done a lot of research on city expansion using RS and achieved good results [79]. RS and GIS tools were used to assess changes in land-use/land-cover patterns [10, 11] and valuable information was gained for analysis of effects of climate change and environmental impacts of human activities. Wohushan region of Jinan is the important groundwater supplying region. The landuse changes will significantly affect the ecological environment of the region. The main aim of this study was to determine land use changes in this region using multitemporal Landsat data for the period of 1987–2015.
