酸沉降临界负荷研究中的不确定性

Uncertainties in the Study of Critical Loads for Acidic Depositionx

从临界负荷的定义、所选用的指示生物及其化学临界值、目前所运用的研究方法、实测资料的缺乏等方面讨论了临界负荷研究中存在的不确定性，指出目前应用于酸沉降临界负荷研究中的稳态和动态模型的模拟能力还很有限，有待进一步完善和发展．

The paper discussed uncertainties in assessment of critical loads for acidic deposition from the definition of the critical load,related biological indicators and critical chemical values,the current methods used to determine critical loads of acidic deposition for an ecosystem,and deficient field data.These discussions indicate that the simulation capacity of the current steady state mass balance and dynamic acidification models utilized is very limited and needs further to be improved.
