【摘要】 介绍了敏感性及生态系统对酸沉降的绝对敏感性和相对敏感性的概念，概述了水体和土壤对酸沉降绝对敏感性评价的方法．通过分析比较生态系统中各生态因子对酸沉降的缓冲能力，提出了建立生态系统对酸沉降相对敏感性评价方法的基本原理，并介绍了已建立的评价方法和近期的发展．更多还原

【Abstract】 he conceptions of sensitivity,the absolute sensitivity and the relative sensitivity of ecosystems to acidic deposition have been described.Also an approach to assess the absolute sensitivity of water and soil to acidic deposition has been developed.According to the c.omparison of each eco logical factor’s buffering ability to acidic deposition, a basic principle to establish a method to assess the relative sensitivity of ecosystems to acidic deposition has been provided.Besides,the article had an introduction to the established assessment methods and their recent development.更多还原
