Abstract:
Taking the regional mixed forest system in the upper reaches of Fenhe River as the research object,the soil physical and chemical properties and five kinds of enzyme activities with or without crusts under different forest conditions were determined.The effects of moss crusts on soil fungi and bacteria were studied by DGGE experiment,and the dominant bacteria were determined by sequencing.The results showed that moss crusts increased the soil water capacity,organic carbon,total nitrogen and total phosphorus contents,and the activities of sucrase,urease,catalase,polyphenol oxidase and alkaline phosphatase,and increased the complexity of soil fungal bacteria Spirochetes and acidobacteria are the dominant genera of bacteria,while fimbria and Chaetomium are the dominant genera of fungi.Biological soil crust plays an important role in soil restoration of Fenhe River.
