Land Cover Change in Aksu Region of Xinjiang from 2000 to 2020
To analyze the land cover change and its influencing factors in the Aksu region,the land use transfer matrix and landscape pattern analysis methods were used to interpret remote sensing images and draw a map of the current situation of land cover change in different years.The results showed that the land use types in the Aksu region had undergone significant changes.From 2000 to 2020,there had been a significant increase in arable land,urban and rural land in the Aksu region,while other land types had been decreasing.During the same period,the climate had shown a warm and dry characteristic.The correlation analysis showed that there were certain differences in the correlation between the landscape pattern index and the areas of 6 land types in different years.And the correlation between the number of patches and the area of land types decreased from 0.6 in 2000 to 0.3 in 2020,the correlation between the landscape segmentation index and land type area increased from 0.6 in 2000 to 0.9 in 2020.The transfer of grassland to unused land was 6 255 hm2,while the maximum transfer of arable land to grassland was 3 706.16 hm2,and the transfer of unused land to grassland was 11 848.8 hm2.The landscape pattern analysis showed that the landscape in the Aksu area was fragmented,with a decrease in land carrying capacity and a weakened ability to resist ecological risks.
