Abstract:

Habitat quality was an important basis for human well-being and the realization of sustainable development. Based on the land use data in 2000, 2010 and 2020 of the Gonghe Basin, the InVEST was applied to analyze the spatiotemporal changes in habitat quality, and the PLUS model was used to predict the spatial pattern under different development scenarios in 2030, and to explore the driving factors of regional habitat quality. The results show that: (1) From 2000 to 2020, the main land use types in the Gonghe Basin were grassland and unused land, with an overall increase in grassland area and a significant decrease in unused land. The spatial distribution pattern was characterized as low in the central part and high around of habitat quality, with a trend of increasing and then decreasing over the past 20 years. (2) The habitat quality index under the natural growth, ecological protection, and urban expansion scenarios in 2030 was 0.5332, 0.5369, and 0.5309, respectively. Under the ecological protection scenario, the area of forest land and grasslands was larger, which was more conducive to the improvement of habitat quality in the study area. (3) Land use was the dominant factor of changes in habitat quality, followed by soil type and NDVI. The expansion of construction land was the main reason for the decline in regional habitat quality over the past 10 years. The results of the study can provide a scientific basis for the ecological protection and sustainable utilization of land resources in the Gonghe Basin.
