本论文以三江源核心地区典型高寒嵩草草甸、重度退化草地和人工重建的草地为基点,采用土壤微生物学和土壤学的原理、方法,对土壤微生物数量进行了研究,探讨了高寒草甸退化及其退化草地恢复重建对土壤微生物的影响程度,旨在为研究高寒草甸退化机理和运用人工草地改良土壤性质、提高其稳定性提供土壤微生物和土壤养分方面的理论依据,为三江源区退化高寒草地恢复提供参考信息
All into the soil microorganisms in soil organic matter decomposition and transformation, and in maintaining the ecological balance of the biosphere and for providing a wide range of human, a large number of untapped resources play an important role. Soil microorganisms in terrestrial ecosystems is the most active components, responsible for the decomposition of animal and plant residues important mission of promoting the eco-system of energy flow and material circulation, maintain normal functioning of ecosystems, three main types of soil microorganisms (fungi and actinomycetes fungi and bacteria) have a powerful enzyme system, decomposition of organic matter in the capacity of the complex is particularly virulent, can lead to soil in plant residues of the major components - cellulose, lignin and pectin, such as the decomposition of the soil can break down non - nitrogen and nitrogen-containing organic compounds, is a natural material and the main decomposers in the soil organic an
