A study on the area land use/land cover change and driving mechanisms applying RS/GIS
Based on RS (Remote Sensing) data sources and GIS (Geographic Information System)technology and by ways of mapping models and LUCC analysis models, the land use and land cover change of 300m off the central line of YuJing Expressway are being studied. The qualitative and quantitative evaluations of land use and land cover change in that area unveil the temporal and spatial variation, the process, the trend and the driving mechanism of land use and land cover change before and after highway construction. The analysis results indicate, over a period of ten years, the change range of area land use of YuJing Expressway has been comparatively high and the quality of ecological environment has been strengthened as well, in fact, the highway road-area ecological environment development serves as the most crucial driving factor.
