| 摘 要： | 从粮食减产及质量下降的直接损失和生物多样性降低的间接损失2个方面,计量了我国农田土壤污染的环境成本。结果表明,1990~2005年我国粮食生产造成的农田土壤污染的环境成本约为208.54亿元/a,其中粮食减产及质量下降的直接损失为21.61亿元/a,农田生物多样性降低的间接损失为186.93亿元/a。

| Abstract: | The environmental cost of Chinese farmland soil contamination was measured from two aspects of the direct loss from grain reduction and quality decrease and the indirect loss from the biodiversity reduction.The result showed that the annual average environmental cost of farm soil contamination caused by Chinese grain production in 1990～2005 was 20.854 billions yuan,among which,the direct loss from the grain reduction and quality decline was 2.161 billions Yuan per year,while the indirect loss from the farmland biodiversity decrease was 18.693 billions yuan per year. |
