摘要
本文采用模拟酸雨方法,考察了峨眉山不同区域冷杉生长正常区和受害区的土壤样品,在酸沉降影响下,土壤特性所发生的改变,测定了土壤酸碱度及主要元素含量。同时以未受到酸沉降侵蚀的贡嘎山土样作为对照点,探讨由酸沉降所造成的土壤酸化,进而引起土壤特性改变与冷杉生长间的关系。
The dripping experiments of the soil were done by using the simulated acid rain. Its aim is to observed and study the changes of the characteristics of different districts soil samples at Mt. Emei where the fir forest grow well and badly under the acid precipitation , and to determine soil pH and the amounts of main elements in soil samples. In the meanwhile,the soil samples at Mt. Gongga with the elevation of the same meters as Mt. Emei which are not eroded by acid preccpitation were also studied as compared samples. The results showed that there exits good correlation between the changes of soil characteristics resulted from acid precipitation and the growth of the fir forest at Mt. Emei.
