- Abstract:
- In order to study the Tianshan Mountains land use change and land degradation status, land use/cover change and land degradation within 20 years in the region were analyzed based on remote sensing data of 1990, 2000 and 2010, and by selecting the range of land use change, land use dynamic degree and intensity index, and combining with the transfer matrix. The area of farmland and urban and rural residents and industrial land continued to increase from 1990 to 2010, and increased by 91.05% and 60.19%, respectively. Meadows and glaciers or permanent snow area significantly reduced, decreased by 15.45% and 28.97%. Based on the transfer matrix, degeneration of grassland and permanent glaciers into desert was obvious. Various land-use types, land-use change in grassland intensity index was up to -0.5056%, followed by arable land, which is 0.4091%. The main land use types in the transfer direction in the study area was grassland and glaciers/permanent snow into the desert, desert and grassland into arable land, desert and grassland mutual transformation, area was under control, but the trend of the conversion of the saline land to desert was obvious, and losses of permanent glaciers was rapid.
