Abstract
Till now, Three Gorges Project has been built for about 15 years. The land use/land cover changes (LUCC)and environment changes in Three Gorges Reservoir Region has always been the focus issues, which is the reason of the paper. Mastering the rule of LUCC in Three Gorges Reservoir Region, firstly, is of advantage to wake up to the potential problems in Three Gorges construction, secondly, can provide reference to the sustainable land planning and administration of reservoir region. The Remote Sensing (RS) method provides abundant and real-time information, and Geographic Information System (GIS) has powerful functions in data processing and spatial analysis. The combination of RS and GIS has inestimable advantages compared with the traditional methods, and is highly effective in monitoring dynamic changes of the land use/land cover. In the paper, the realizing steps and methods of how to monitor the land use dynamic changes by RS and GIS are provided.
