摘要
以小流域为背景,研究生态系统的行为是理解自然过程和人为过程的有效途径之一。本文以一温带森林生态系统小流域为例,通过分析和比较该生态系统的不同时空状态下的水化学过程,研究了该生态系统对酸雨和土地利用的响应行为。结果表明,该小流域生态系统具有较强的缓冲功能。沿森林生态系统水循环的路径,作者探索了该小流域生态系统缓冲能力形成的内在基础。
In the context of small river catchment, the study of ecosystem has been regarded as oneway of understanding both natural processes and the effect of human activities,Exampled by a tem-perate forested ecosystem catchment,respondent behaviour of the catehmen t to acid rain fall andlanduse change has been studied by comparing ten1poral and spatial data of water chemistry of the e-ccoystem. The research has shown that the eccaystem has the buffering ability to aclti rainfull andlim ited cutting of timber.Following the route of water circulation within the eosystem,the authorhas revcaled the foundation for the formation of the buffering function.
