摘　　要：生物土壤结皮是由土壤表层颗粒物、植物和微生物群落胶结形成的混合物,对特殊环境下元素生物地球化学循环具有重要作用。论文概述了生物土壤结皮组成、类型和演替过程,简要总结了生物土壤结皮的4种功能特性,分析了生物土壤结皮对高山生态系统磷生物地球化学循环的作用方面的研究进展,对生物土壤结皮影响磷循环的过程和机制进行了探讨。在此基础上,从高山生物土壤结皮对磷生物有效性提升的作用角度,提出高山裸地土壤和植被快速发育的技术路径,为高山生态系统修复提供参考。Biological soil crusts(BSCs)are mixtures formed by the cementation of soil surface particulate matter,plant and microbial communities,and play an important role in elemental biogeochemical cycling in special environments.This thesis outlines the composition,types and succession processes of BSCs,briefly summarized four functional properties of BSCs,analyzed the research progress in the role of BSCs on phosphorus biogeochemical cycling in alpine ecosystems,and discussed the processes and mechanisms of BSCs affecting phosphorus cycling.From the perspective of the role of alpine BSCs on phosphorus effectiveness enhancement,a technical pathway for the rapid development of alpine bare land soil and vegetation is proposed to provide a reference for alpine ecosystem restoration.
