摘要

采用酸滴定法测定了三峡库区四种典型土壤的酸缓冲容量

并用土壤的酸缓冲容量计算了四种土壤对酸雨的临界负荷。结果表明:土壤的pH值和CEC含量越高

盐基离子释放量越大

土壤酸缓冲容量越大;三峡库区四种典型土壤的临界负荷存在明显的差异

临界负荷的大小顺序为:红棕紫泥>红紫泥>灰棕紫泥>黄壤

红棕紫泥土壤对酸敏感程度显著小于其它三种土壤。

Abstract

Acid titration was performed to probe the acid buffering capacity of four types of typical soils from the Three Gorges Reservoir Region.The acid buffering capacity of soil was also applied to calculate the critical load for acid rain.The results indicated that the higher the pH value and CEC content of the soil

the greater the basic ions and acid buffering capacity of the soil would be.The critical load for acid rain was obviously different for four types of typical soils from the Three Gorges Reservoir Region.The order of the critical load for acid rain was red-brown purplish soil>red purplish soil>grey-brown purplish soil>yellow soil.The sensitivity of red-brown purplish soil to acid was much less than that of other three soils.
