评述水体、土壤和整个生态系统对酸沉降敏感性评价的各种方法，这些方法用系统 的不同物理化学性质表征它们缓冲酸输入的能力。

Methodology for Assessing the Sensitivity of Ecosystems to Acidic Deposition and Its Progress

Different methods for assessing the sensitivity of water,soil and whole ecosystem to acidic depositions are summarized.These methods indicate the acidic input buffering ability of these systems with different physico chemical characteristics.By comparing and analyzing,it is pointed out that the methods which are developed with some chemical indicators expressing the acidic input,buffering ability of water and soil are essentially the kinds of absolute assessment to some parts of ecosystem.The relative sensitivity assessing method attempts to indicate the buffering ability of whole ecosystem to acidic depositions,which is developed based on those environmental site factors that indicate potential ecosystem response to those depositions,and the derived sensitivity maps can be used to make a decision on acidic deposition control.
