Water quality improvements, equivalent annual costs per kg of harvested shrimp, spatial requirements, and ecosystem services associated with every treatment option across each production scenario.
收藏资源简介:
Water quality criteria are expressed as a percentage decrease from initial condition. Equivalent annual costs assess the discounted NPV over the lifespan of each treatment per kg of harvested biomass. Spatial criteria are expressed as the area in m2 necessary to treat 1 ha of production pond, where 1 ha = 10,000m2. Select ecosystem services are presented with service value (full assessment in Table C in S1 Text). Threshold target values, shaded green, are removal rates of at least 40%TN, 40%TP, and 70%TSS, EAC less than $0.18 kg-1, spatial requirement less than 10,000m2 (1ha), and at least ‘Medium’ ecosystem service provision. Values below targets are orange and cross-hatched cells indicate ‘not applicable’.
水质标准以相较于初始状态的百分比降幅表示。等价年度成本(Equivalent annual costs)用于核算各处理方案全生命周期内、单位收获生物质对应的折现净现值(discounted NPV)。空间标准以处理1公顷养殖池塘所需的面积(单位为平方米,1公顷=10000平方米)表示。选取的生态系统服务以服务价值形式呈现,完整评估详见附录S1文本中的表C。绿色底纹标注的阈值目标值为:总氮(TN)、总磷(TP)去除率不低于40%,总悬浮颗粒物(TSS)去除率不低于70%;等价年度成本低于0.18美元·千克⁻¹;空间需求小于10000平方米(即1公顷);生态系统服务供给等级至少为"中等"。未达目标的数值以橙色标注,带交叉阴影线的单元格表示"不适用"。
