摘要：
Objectives: The requisition-compensation balance is one of the important measures for farmland protection in China. During the development of cultivated land protection policies from traditional quantity protection to quantity-quality-ecology integration protection, few studies have examined future potential impacts of different requisition-compensation balance policies. Methods: We take Zhaoyuan City, Shandong Province as an example to construct a multi - scenario simulation model of land use change incorporating requisition - compensation balance of arable land，design five simulation scenarios, namely, baseline scenario, quantity protection of cultivated land, quantity-quality protection, quantity-ecological protection and quantity-quality-ecological protection. Then we analyze the changes in quantity, productivity and habitat quality of arable land in 2030 under different protection strategies. Results: The results show that the requisition-compensation balance policies will increase the quantity, grain yield and habitat quality of cultivated land by 7.2%, 0.63% and 0.70% on average compared with the baseline scenario. In the quantity-quality-ecological protection scenario, grain yield and habitat quality are likely to be higher than those in other scenarios, and their trade-off relationships will be better reconciled. Conclusions: This work will provide solid support for evaluation of various requisition-compensation balance strategies and adjustment of farmland protection policies. © 2023 Wuhan University.
