海洋牧场碳汇资源生态补偿标准

海洋牧场建设是中国扩增海洋碳汇，实现碳中和战略目标的有效途径。碳汇具有明显的外部性，只有确定合理的补偿标准才能调动海洋牧场建设经营者积极性。以海洋牧场中藻类、贝类、鱼类、甲壳及其他类经济性碳汇资源为研究对象，利用最优化模型核算了碳汇资源生态价值的补偿标准。研究结果表明：藻类、贝类、鱼类、甲壳及其他类的生态补偿标准分别为134.94元/t、820.05元/t、782.39元/t、3764.16元/t，补偿标准存在种类间差异性。研究结果可为优化当前海洋牧场生态补偿政策提供理论参考。

Ecological compensation standards of carbon sink resources in the marine ranch

The construction of marine ranches is an effective way to increase the ocean carbon sink and achieve the strategic goal of carbon neutrality in China. Carbon sink has obvious externality, only to determine a reasonable compensation standard to mobilize the enthusiasm of marine ranch construction operators. This paper takes economic carbon sink resources such as algae, shellfish, fish, crustacean and other species in the marine ranch as the research object, and accounted for the compensation criteria for the ecological value of carbon sink resources using an optimization model. The results indicated that the ecological compensation standards of algae, shellfish, fish, crustacean and other species were 134.94 yuan/t, 820.05 yuan/t, 782.39 yuan/t, and 3764.16 yuan/t, respectively, and there was inter-species variability in compensation standards. The results can provide a theoretical reference for optimizing the current ecological compensation policy for the marine ranch.
