河北省污水灌溉农业环境污染经济损失评估

Economic loss evaluation of agricultural environmental pollution from wastewater irrigation in Hebei Province

摘要: 以河北省为例，采用市场价值法、人力资本法和工程费用法对污水灌溉所造成的农田土壤、地下水和作物污染及其对人群健康的影响进行经济损失评估，研究结果表明2000年河北省污水灌溉造成的环境污染总经济损失为7．37亿元，占农业生产总值的0．87％，其中以人群健康损失所占比重最大，占污染总经济损失的95．3％，地下水和作物污染经济损失相对较小，故污水灌溉的潜在负面影响，尤其是对污灌区人群健康的影响应引起高度重视。

Abstract: Taking a case study from Hebei Province．the economic loss from soil pollution，ground water pollution，crop pollution and health damage caused by sewage irrigation is evaluated by using the market value method，labor cost method．and engineering expenditure method． The results show that the total economic loss from environmental pollution caused by wastewater irrigation is 737 million yuan．which is 0．87％ of total agricultural output．The economic loss from health damage takes 95．3％ of total loss．So the environmental pollution from wastewater irrigation should be regarded enough．
