• Utilized PLUS model for APA simulation under varied scenarios. • Integrated 40 key indicators for accurate forest type classification. • Analyzed APA spatial distribution in Yunnan for 2035 and 2050. • Proposed ’adapting to local conditions and time’ development strategies. Afforestation is recognized as a crucial strategy for mitigating global warming. Therefore, appropriate areas and scales of afforestation needed to be accurate identify and plan, due to the varying levels of economic development and ecological protection across different regions and future scenarios. This study utilized land use data, natural and socio-economic data as the indicators from 2000 to 2020. The Patch-level Land Use Simulation Model (PLUS) was employed to simulate and analyze afforestation potential areas (APAs) under four scenarios: Natural Development (NDS), Ecological Protection (EPS), Urban Development (UDS), and Cultivated Land Protection (CLPS) for the years 2035 and 2050. The results shown that: (1) the spatial distribution of APAs in Yunnan Province under different scenarios shown significant spatial heterogeneity. The APAs are mainly concentrated in economically backward areas with favorable natural conditions. Moreover, the APAs are primarily found around existing forests. (2) The EPS scenario revealed the highest afforestation potential, with 14,132.14 km 2 and 13,825.76 km 2 of high-APAs, and 5,204.17 km 2 and 5,262.4 km 2 of low-APAs expected by 2035 and 2050, respectively.
