摘要
陆地生态系统是酸沉降的最大接受者和缓冲者，故对陆地生态系统酸沉降缓冲能力及缓冲容量的研究是衡量酸沉降对生态影响和危害的中心环节。本文在总结以往研究的基础上，从陆地生态系统物质流各个环节的角度讨论了影响陆地生态系统酸沉降缓冲能力的各种因素，并提出了研究工作应注意的问题。
Terriecosystems are the largest receptor and buffer of acid deposition , so
study on buffer capacity of terriecosystems is the most important part in evaluating the effect
and damage of acid deposition on ecosystems . On the basis of previous research results , this
paper discussed the affecting factors on buffer capacity of terriecosystems from the
geochemical circulation of elements . The sensitivity was related not only with the buffer
reactions in soils but those in different layers of plants. Further, problems would be met with for
future research were suggested.
