- Abstract:
- Land use is the most basic economic activity of human. In the thought of the sustainable development, research on the characteristics of land use changes is an important development trend of land use in China in recent years. Taking five periods TM images of the Three Gorges Reservoir Area as the data source, we used the GIS technology to extract the land use map of each period, analyze the quantity, distribution and the change trend of the type of land use, and the characteristics of land use degree. The results indicated that the quantity of land class, including cultivated land, grass land, forest land, unused decreased during the period from 2000 to 2013. Then the quantity of construction land, and water area increased. At the same time, the land use dynamic degree of each land class was different, construction land and water area dynamic degree were high, while the grassland, cultivated land and forestland dynamic degree were very low. During the research period, the trend of the land use degree increased in Three Gorges Reservoir area. These research methods are helpful to understand the characteristics of land use changes in recent 13 years, and the results could provide reference value for sustainable development of land use and land planning in the Three Gorges Reservoir area.
