- Abstract:
- Research on the land use changes based on RS and GIS,can reveal the rules of spatial changes. Taking Chongqing Mountain Cities as the study area, the eight periods of TM images were chosen as the basic data sources, the characteristics of land use changes were analyzed systematically. The results indicate that the quantity of those land class, including cultivated land, grassland, unused land decreased from 1985 to 2010. Then the quantity of forest land, construction land, and water area increased. At the same time, the change degrees and processes were different of each land class. The dynamic degree for each class was different, unused land and construction land dynamic degree were high, while the cultivated land and forest land were very low. The land utilization degree increased in the past twenty-six years, but the change processes had different stages. The results can provide references for land management and sustainable land use.
