摘　　要：应用人力资本法(HCA)评估了华北典型高产粮区地下水资源硝酸盐污染的价值损失.引用国外的研究结果,建立了硝酸盐污染浓度与健康损害的剂量反应关系,分病因预测了地下水污染超标区增加的死亡人口数量.按照潜在寿命损失人年(YPLL)的计算方法,构造了人力资本损失总量估算函数.应用该函数评估了研究区农业面源污染地下水资源的价值损失为860.8万元/a,相当于每公顷耕地面积上增加外部环境成本293.9元/a.The human capital approach (HCA) was applied to valuate the loses of groundwater source pollution by nitrate in the typical high-yielding farming region North China. Quoting the foreign study results the dose-response relation of nitrate pollution concentration and health damage were established. Increase of population death quantity in the groundwater over standard pollution area was predicted with part pathogeng. According to the calculation method of Years of Potential Life Lost (YPLL), a function of calculating the total loses of human capital damaged was constructed. Applying this function the annual loses of groundwater resources polluted by agricultural surface pollution source in the study area were valuated to be about 8.6 million yuan, equivalent to an increase of external environmental cost 293.9yuan/a per hectare of farmland.
