Oasis Change Characteristics and Influencing Factors in the Shiyang River Basin, China

The variability of the natural environment and complexity human activities result in dynamic changes oasis areas, which is directly related to sustainable development arid semi-arid areas. In order better balance economic environmentally development, based on land use data social from 1980 2015, this paper analyzed change characteristics under factors Shiyang River Basin Northwest China. results indicated that showed an expansion trend with mainly occurring diluvial alluvial fan, along middle lower reaches river. changed actively areas at elevation 1350 m, a slope 2°, distance 1500 m rivers, precipitation 120 mm temperature 15 °C. Furthermore, evolved towards gentler slopes altitudes, migrated closer rivers before 1992 farther away afterwards. Population growth were important inducers change, government policies agricultural benefits ecological conservation also influenced especially after 2000. evolution patterns distribution revealed study can provide reference for promoting restoration development.
