受污染土壤的农业损失评估法初探

Assessment Approach of Agricultural Loss from Contaminated Soil

基于受污染土壤的特定涵义及其存在特征,提出了可用于受污染土壤造成农业损失的评估法。受污染土壤造成的农业损失评估法可分为当年评估与后评估,相应地农业损失评估计量是当年评估值与未来年份内应当考虑的若干个后评估累计值的加和。可将计算机信息系统应用于受污染土壤的农业损失评估。

Based on special conception of contaminated soil and its characteristics, assessment approach of agricultural loss from contaminated soil should bederived from current assessment and successive assessment. The total loss for agriculture from contaminated soil is summed from both values of current assessment and successive assessment. A computed information system described in the present study can be used for the assessment on agricultural loss from contaminatedsoil.
