【摘要】 文章介绍了荒漠藻类生长在荒漠化土地上的土壤藻类的种类组成和分布,影响荒漠藻类分布的环境因子,荒漠藻类在物质循环及土壤结皮形成和发育中的重要作用,以及荒漠藻类能够在极端环境条件下生长的适应机制等。生物结皮在荒漠土壤表层的水分分布状况、土壤稳定性和荒漠生态系统的演替中起着重要作用,对荒漠其他生物也有着重要的影响。最后阐述了荒漠藻类在工业和环境工程上的应用和发展前景。更多还原

【Abstract】 Desert algae mainly refer to soil algae growing in desertification regions. The article introduces algal species composition and distribution, affecting factors of algal distribution, the functions in substances cycle, the formation and development of desert crust, and the mechanisms of adaptation in surviving extreme environment of desert algae in arid regions. Desert crust plays an important role in soil hydrological property, soil stabilization and succession of desert ecological system. It also has a significant influence on other organisms. In the end, it introduces the application of desert algae in industry and environmental engineering and the prospect in future research.更多还原
