Research on Multi-objective Collaborative Development Decision-making of Integrated Watershed Management Under the “Dual Carbon” Target

Watershed systems, as open ecological and economic units connecting upstream and downstream, play a crucial role in achieving carbon peak and carbon neutrality targets.This study based on the analysis of watershed carbon management, constructs a multiobjective planning model for carbon emission reduction at the watershed scale.The model aims to minimize carbon reduction costs and maximize comprehensive ecological benefits, considering environmental constraints, resource constraints, and technological constraints.It utilizes multi-objective planning algorithms to obtain optimized strategies and spatial allocation schemes for watershed carbon emission reduction.The model is applied to case studies in typical watersheds to validate its scientific rigor and practicality.This research provides quantitative methods and decision support for carbon emission management in watershed systems, offering innovative value.
