Abstract:

Habitat quality is an important index for measuring the quality of the regional ecological environment. Its study in arid and semi-arid watershed areas holds both theoretical and practical importance. Based on multisource data such as natural geography and remote sensing images, this study uses research methods such as the center of gravity migration and the InVEST model. This study aims to reveal the temporal and spatial evolution law of habitat quality in the Bosten Lake Basin of Xinjiang, China, from 1980 to 2020. This study also uses the FLUS model to simulate the temporal and spatial evolution of land use in 2025 and 2030, shedding light on the corresponding habitat quality shifts under different land use change prospects. The results can be summarized as follows: (1) From 1980 to 2020, the average habitat quality in the Bosten Lake Basin decreased from 0.546 to 0.521. High-quality habitat areas were greatly reduced, with the regional center of gravity shifting northward. Conversely, low-quality habitat areas expanded and their center of gravity moved northeastward. Notably, the overall intensity of habitat degradation in the watershed weakened during this period. (2) Under the natural development scenario, industrial production land and other ecological land have increased substantially in the Bosten Lake Basin. Meanwhile, in the ecological priority development scenario, the development trend of water ecological land shifted from decline to growth and moved to grassland ecological land and other ecological lands in the Bosten Lake Basin. In the economic development priority scenario, the boundary between urban living land and industrial production land in the Yanqi Basin and oasis plain expanded. This study provides a scientific basis for land use planning and habitat quality improvement in arid and semi-arid basin areas.
