Simulation of spatiotemporal patterns of habitat quality and driving mechanism in Anhui province, China

Understanding the characteristics of habitat quality and its influence under land use change is crucial for rapid urbanization, regional ecological protection, national restoration optimization layout. This paper examined Anhui Province, China, through topo-graphic data, climate human activity data from 2000, 2010, 2020. To reveal impact mechanisms, assessed province’s spatiotemporal evolution by Patch-generating Land Use Simulation (PLUS) model, Integrated Valuation Ecosystem Services Trade-offs (INVEST) geo-graphic probe model. The results showed that: 1) From 2000 to 2020, Paddy field, Dryland, Wooded covered 70% study area. integrated dynamic attitude was 0.51%, with active changes in open a continuous increase attitude. Compared spatial distribution types 2030 remain largely unchanged. However, fields Drylands still show an increasing trend, while land, Reservoir ponds, Urban demonstrate small decreasing trend. All other unchanged; 2) Secondly, between gradually decreased, percentage poor increased 1.47% worse decreased −1.41%. classes exhibited trend; mean 0.01 compared 2020 2030, mainly distributed southwestern eastern edges province; 3) DEM, aspect, precipitation, evapotranspiration have high explanatory power quality, variable Places has significantly 2010 Natural factors laid down graded pattern location intensity activities drove quality. Analyzing mechanism behind Province provides theoretical basis planning.
