摘要
对4种土壤进行各种模拟酸雨处理,土壤基质颜色、微结构、骨骼颗粒、形成物等土壤微形态特征均发生变化。变化程度与土壤本身的酸度有密切关系。
Four kinds of soil(limy purple soil,neutral purple soil,acid purplesoil and yellow soil)were treated by a variety of simulant acid rains.Examination of the thin sections of the treacted soils indicated thatchanges occurred in their micromorphological characteristics,includingthe color of soil matrix,soil fabric,skeleton grains and formationmatter,etc.Degree of variation appeared to be closely related to theacidity of the soil per se.
