摘　　要：生态系统服务供需错配会影响区域公平,制约区域可持续发展,制订合理的生态补偿标准可以有效协调区域环境保护与经济发展。目前,耕地生态补偿探讨较少,处于概念分析阶段,缺乏定量评估。本研究基于2000--2020年江西省粮食供应服务供需格局,识别粮食供应服务供给区与需求区,引入比较生态辐射力模型量化粮食供应服务流,并定量评估江西省耕地生态补偿标准。结果表明:研究期间,江西省粮食供应服务存在供需错配现象,区域供需关系由赤字转为盈余但差额减小,耦合协调度相对较低。粮食供应服务流量由快速上升转换为缓慢上升,流向表现为由江西省中部流向四周。耕地生态补偿总额不断上升,由2000年的22.14亿元增至2020年的126.38亿元。江西耕地生态补偿支付方向主要表征为由各地级市经济发达区县向周边耕地资源丰富地区进行耕地补偿。该研究不仅为区域可持续发展提供理论支持,也可为耕地生态补偿提供一定借鉴。Mismatch between supply and demand of ecosystem services will affect regional equity and restrict regional sustainable development.The formulation of reasonable ecological compensation standards can effectively coordinate regional environmental protection and economic development.At present,the ecological compensation mechanism of cultivated land is rarely adressed,which is in the conceptual analysis stage and lacks quantitative evaluation.Based on the supply and demand pattern of food supply services in Jiangxi Province from 2000 to 2020,we identified the supply and demand areas of food supply services,introduced comparative ecological radiant force model to quantify the flow of food supply services,and quantitatively assessed the ecological compensation standard of cultivated land.The results showed that there was a mismatch between supply and demand of food supply services in Jiangxi.The regional supply and demand relationship changed from deficit to surplus but the difference decreased.The degree of coupling coordination was relatively low.The food supply service flow changed from rapid rise to slow rise,flowing from the central part of Jiangxi to the surrounding areas.The total amount of ecological compensation for cultivated land continues to rise,from 2.214 billion yuan in 2000 to 12.638 billion yuan in 2020.The payment direction of cultivated land ecological compensation in Jiangxi was mainly characterized by the compensation of cultivated land from economically developed districts and counties of prefecture-level cities to the surrounding areas with rich cultivated land resources.This study provided theoretical support for regional sustainable development and some reference for cultivated land ecological compensation.
