摘要/Abstract

摘要： 为明确退化高寒草甸土壤真菌物种组成、群落多样性及功能结构等对补播的响应变化规律，本研究采用高通量基因检测技术对青藏高原中度退化及人工补播草地土壤真菌群落特征及其调控因子等进行了研究。结果显示：退化草地补播后土壤真菌特有OTUs增加，子囊菌门真菌丰度升高，被孢霉菌门和担子菌门真菌丰度降低；补播提高了退化草地土壤真菌Chao1指数，而对真菌Shannon指数和Simpson指数无明显影响；退化草地与补播草地间土壤真菌群落结构差异显著，补播后土壤病理型、病理-腐生型及共生型真菌丰度降低，土壤真菌群落及功能结构发生明显改变；土壤pH、总有机碳含量、铵态氮含量、硝态氮含量、全磷含量、全钾含量和碳氮比对土壤真菌起主要调控作用。

Abstract: To clarify the response of soil fungal species composition,community diversity and functional structure of replanting in moderate-degraded alpine meadow,we studied the soil fungal community characteristics and their regulations factors by high-throughput sequencing technique. The results showed that after replanting,the soil fungal specific OTUs and the ascomycetes abundance were increased,while the abundance of mortierellomycota and basidiomycota were decreased. Soil fungal Chao1 index in replanting grassland increased significantly,while Shannon index and Simpson index had no significant changes. There were significant differences in soil fungal community structures between degraded grassland and replanting grassland. After replanting,the fungal abundance of pathotroph,pathotroph-saprotroph and symbiotroph decreased. The soil fungal community and functional structures changed significantly by replanting. Soil pH,TOC,AN,NN,TP,TK and C/N play a major regulatory role on soil fungi.

Key words: Degraded alpine meadow, Replanting, Soil fungal species composition, Community and functional structures
