Urban Expansion and Driving Forces Analysis of Jinan Based on Remote Sensing and GIS Technology

Urban expansion is a complex economic and social process and has been a hot topic not only in the management of sustainable development but also in the fields of remote sensing and geographic information science (GIS). Jinan is chosen to be the study area, as a fresh case, has not been systematically studied so far on the published literature especially its urban growth pattern and evolution prediction. Based on remote sensing and GIS technology, urban land of the year 1979, 1987, 1995, 2000, 2002, 2004 and 2008 are extracted from multi-original remote sensing data (Landsat MSS/ TM/ETM+, CBERS02B) and analyzed by GIS. Time scale of this research ranges from 1979 to 2008, and is divided into 6 periods (1979~1987, 1987~1995, 1995~2000, 2000~2002, 2002~2004, 2004~2008). (1) Preprocessing such as radiant calibration and geometry extract calibration was executed on the multi-source remote sensing data. (2) Based on the software platform MGE and ArcGIS, urban land was extracted. (3) The spatial-temporal regulation and pattern characteristics of Jinan from the year 1979 to 2008 were quantitatively described in details by quoting indices such as urban expansion intensity, centroid index and so on. (4) The driving forces of urban expansion were analyzed by the principal composition analysis (PCA) method. The systematic research of urban expansion pattern and driving forces analysis in Jinan could be beneficial to local planning system.
