- Abstract:
- Soil salinization poses a substantial threat to the eco-environmental stability of the oasis irrigation areas. The downstream of Kaidu River irrigation areas located in the Tarim Basin, Xinjiang as an example, based on GIS platform, taking the remote sensing images in 1990 and in 2008 as the main information, by interpreting the images with combination of the field survey, the status quo, degree and distribution characteristics of the soil salinization are analyzed. Some results are concluded as follows: the saline land has decreased in area and degree in the studied period of 20 years. Area of saline land has decreased from 1928.90 km2 in 1990 to 1513.40 km2, and the decreased area is 415.50 km2, decreased by 21.87 km2 per year on average, and the decrease rate is 1.13% per year. The degree is weakened, but the saline land has constituted a serious threat to the ecosystem environment and oasis economic development, thus, more concern should be given to it.
