China has implemented policies to promote fuel ethanol development and achieve its dual-carbon goal. Under the policy, significant modifications will occur in allocation of land use resources within raw material cultivation regions. In process change, ensuring food provision protecting regional carbon sink are also crucial for sustainable development. This study explores distribution Guiping section Yujiang River basin, where bioethanol materials cultivated. Using CLUE-S model, a multi-objective model prioritizing economic ecological benefits is constructed. Four scenarios (i.e., natural expansion scenario (NES); conservation (FCS); feedstock (BCS), sinks (CCS) simulated, predicting resource by 2030. The total decreased 285.60 gC·m−2·a−1, showing seasonal trend higher levels summer lower winter. 2030, NES scenario, while it increased FCS BCS scenarios. CCS had largest increase, approximately 582.27 × 103 tC. These simulated consider various environmental factors, providing scientific basis efficient resources. They have implications local energy, economic, environmentally development, as well promoting achievement neutrality.
