摘要: Land use/cover change (LUCC) is becoming more and more frequent and extensive as a result
of human activities, and is expected to have a major impact on human welfare by altering ecosystem
service value (ESV). In this study, we utilized remote sensing images and statistical data to explore the
spatial-temporal changes of land use/cover types and ESV in the northern slope economic belt of the
Tianshan Mountains in Xinjiang Uygur Autonomous Region, China from 1975 to 2018. During the study
period, LUCC in the study region varied significantly. Except grassland and unused land, all the other land
use/cover types (cultivated land, forestland, waterbody, and construction land) increased in areas. From
1975 to 2018, the spatial-temporal variations in ESV were also pronounced. The total ESV decreased by
4.00×108 CNY, which was primarily due to the reductions in the areas of grassland and unused land.
Waterbody had a much higher ESV than the other land use/cover types. Ultimately, understanding the
impact of LUCC on ESV and the interactions among ESV of different land use/cover types will help
improve existing land use policies and provide scientific basis for developing new conservation strategies
for ecologically fragile areas.
