摘要: 对我国东部7省1市进行了生态系统对酸雨的相对敏感性分析.采用GIS作为空间分析的工具,综合分析了基岩类型、土壤缓冲能力、植被和土地利用方式,以及土壤水分盈余量等多种要素对酸雨的敏感性.

Abstract: This paper describes the application of GIS technology in analyzing ecosystem’s relative sensitivity to acid deposition. East part of China is selected as the research area. Four factor layers, which are base rock, soil type, vegetation and humidity, are used in the process. The sensitivity appraising system and the appraising model are also discussed. Five grades are separated in this research.
