Abstract

The acidified soil caused by the acid rain has become a global problem, however, its effects to the microorganisms in the soil is not well understood. The authors employed a series of physiological and biochemical experiments to test and analyze three typical acidified and the remediated soil like grassland soil on barren hills, masson pine soil, and mixed coniferous and broad-leaved forest soils. The observation shows that the number and categories of microorganisms decreased in the order bacteria> epiphyte >actinomycetes, and the number of microorganisms in different depth of soil decreased in the order 0 20cm>20 40cm>40 60cm.Moreover, separation and identification of bacteria indicates that preponderant bacteria in different soils were distinguishing, so were the soil before and after remediation with the change of soil pH.The results enable us to further understand the characteristics of the remediated acidified soil from the aspect of microbiology.
