苔藓对水土保持益处初探

Preliminary Study on the Benefits of Moss for Soil and Water Conservation

摘要: 苔藓植物作为陆地生态系统中最古老的类群之一，虽个体微小，却在水土保持中发挥着不可忽视的作用。本文从苔藓的生物学特性出发，系统梳理其在固土、保水、改善微生境等方面的核心机制，结合不同生态系统(如森林、喀斯特、红壤区等)的研究案例，探讨苔藓与其他植物的协同效应及人工修复中的应用潜力。研究表明，苔藓通过地表覆盖、根系(假根)固着、水分截留与调节等方式，显著减少土壤侵蚀、增强土壤持水能力，尤其在脆弱生态区具有独特优势。未来需进一步关注苔藓群落动态、气候变化响应及规模化应用技术，为水土保持与生态修复提供新思路。

Abstract: As one of the oldest groups in the terrestrial ecosystem, bryophytes, despite their small size, play a non-negligible role in soil and water conservation. This paper starts from the biological characteristics of bryophytes, systematically combs its core mechanisms in soil fixation, water conservation, and micro-habitat improvement. Combining research cases in different ecosystems such as forests, karst areas, and red-soil regions, it explores the synergistic effects between bryophytes and other plants and their application potential in artificial restoration. Research shows that bryophytes significantly reduce soil erosion and enhance soil water-holding capacity through surface coverage, root (rhizoid) fixation, water interception, and regulation, especially having unique advantages in fragile ecological areas. In the future, more attention should be paid to bryophyte community dynamics, climate change response, and large-scale application technologies to provide new ideas for soil and water conservation and ecological restoration.
