- Abstract:
- [Objective] The aims of this study are to evaluate the habitat quality in Anhui Province, to explore its driving mechanism, and to provide a theoretical reference and scientific basis for ecological environment management and the sustainable and high-quality development of social economy in Anhui Province. [Methods] In this study, Anhui Province was used as the study area to evaluate habitat quality in 2000, 2010 and 2020 based on the InVEST model. The hot spot analysis and MGWR model were used to analyze the natural and socioeconomic impacts on habitat quality in Anhui Province. [Results] The average habitat quality of Anhui Province showed a downward trend from 2000 to 2020, with a decline rate of 3.01%, and the area of poor habitat quality most widely distributed. The spatial distribution pattern of habitat quality was high level in the south and west of mountainous and hilly areas and low level in the north and central part dominated by arable land and building land. Slope, NDVI, construction land ratio and land reclamation rate were the key factors affecting the spatial distribution of habitat quality in Anhui Province, and the average regression coefficients were 0.138, 0.084,-0.213 and-0.557, respectively. Slope had positive effects on habitat quality, NDVI had positive effects on habitat quality in most regions, the positive proportion of the area in the three phases reached more than 80%, and the negative effects of the proportion of building land and land reclamation rate on habitat quality increased and weakened with time, respectively. [Conclusion] The proportion of building land and land reclamation rate can decrease the habitat quality, so the management of land use and the scale of urban expansion should be strengthened in the future.
