【摘要】 将食物生产与碳排放分别作为期望与非期望产出，构建“水-能源-食物-土地-碳排放”耦合（“water-energyfood-land-carbon”nexus,WEFLC）分析框架，选择舟山海岛的果蔬种植、畜牧养殖以及水产养殖典型农业生产案例，进行农业空间评估与低碳规划研究。结果表明，单位产值和单位面积碳排放强度顺序依次为畜牧养殖、水产养殖、果蔬种植，且畜牧养殖的总产值在碳市场中受到影响较大。在维持食物产出不变的情况下，畜牧养殖、水产养殖、果蔬种植可分别通过应用光伏、提升用水效率、引入有机废弃物处理技术等措施，降低水资源、能源、土地资源消耗，实现农业生产的低碳发展。更多还原

【Abstract】 A “water-energy-food-land-carbon ”Nexus(WEFLC)analysis framework was established with food production and carbon emissions as expected and undesired outputs, respectively. Typical agricultural production cases of farming, livestock breeding, and aquaculture in Zhoushan islands were selected to conduct the agricultural space assessment and low carbon planning. The order of unit output value and carbon emissions per unit area is livestock breeding,aquaculture, and farming. The total output value of livestock breeding is greatly affected by the trend of carbon trading. While maintaining the same food output,livestock breeding,aquaculture,and farming section can reduce energy,water,and land resource consumption,and therefore, low carbon emissions are realized for agricultural production by employing photovoltaics and improving the efficiency of water use as well as introducing organic waste-disposal technologies.更多还原
