Abstract:

Habitat quality is an important basis for biodiversity conservation and improvement of the regional ecological environment. With an ecological civilization construction as the background, the spatial-temporal adaptation and driving mechanism of habitat quality is significant to study. Based on land use data in Shaanxi Province in 2000, 2010, and 2020, the characteristics and driving factors in the spatial-temporal adaptations of the quality of habitat in three regions were analyzed using the InVEST model, Theil index model, and geographic detector model. The results showed the following: (1) from 2000 to 2020, the average quality of habitat showed a stable and slightly increasing trend, and the spatial distribution difference was obvious, with the average habitat quality in southern Shaanxi and northern Shaanxi being higher compared to Guanzhong; (2) the difference of habitat quality among the three regions was larger in southern and central Shaanxi compared to northern Shaanxi; (3) the province and the driving factors in the three different regions, vegetation and terrain factors for the habitat quality, and land utilization factor are the main influencing factors of the three major areas affected by the spatial scale. As time goes on, the influence degree gradually strengthens, and the terrain and vegetation factors have different effects on three areas; (4) In addition to single factors, significant impacts on habitat quality changes in the three regions produced cooperative effects on socioeconomic and natural environmental factors.

Key words: habitat quality, InVEST model, geographic detector, driving factor, Shaanxi Province
