Impact of Land-use Type Changes on Soil Nitrification and Ammonia-Oxidizing Bacterial Community Composition
土地利用变化对土壤硝化及氨氧化细菌区系的影响

A comparative study was conducted to determine nitrification potentials and ammonia-oxidizing bacterial(AOB) community composition in 0-20 cm soil depth in adjacent native forest,natural grassland,and cropland soils on the Tibetan Plateau,by incubation experiment and by denaturing gradient gel electrophoresis(DGGE) of 16S rDNA,respectively.Cropland has the highest nitrification potential and nitrate concentration among the three land-use types(LUT),approximately 9 folds and more than 11 folds than that of t...
