RESEARCH AND ANALYSIS OF LAND USE DYNAMIC CHANGE IN QINGDAO BASED ON RS AND GIS IN RECENT TEN YEARS

Land use and land cover change (LUCC) is the hotspot and frontier issue of global environmental research. In this paper, the LUCC of Qingdao was studied from the different aspects using Landsat ETM+ and OLI satellite imagery. Combined with manual visual interpretation, we used the maximum likelihood method to classify the images respectively, and finally formed the 3 phases land use status maps and the corresponding land use status attribute database. Then, the land use dynamic change model and the land use type transfer matrix are adopted to analyze the LUCC situation of Qingdao from 2008 to 2017.The results show that land use change is significant in Qingdao in the past ten years: the cropland and water area continued to decrease, and the residential construction land increased greatly. The cropland mainly convert to the residential construction, and as a result, urbanization process of Qingdao is accelerating now.
