摘　　要：藻类和苔藓植物是荒漠植被演替过程中常见的两类先锋植物,同时也是生物结皮中生物量最大的2个类群。该文综述了近年来干旱半干旱荒漠地区生物结皮中藻类和苔藓两大类植物区系及其生态作用的研究进展,重点介绍藻类结皮、苔藓结皮的生态作用以及二者之间存在的生态学关系。在此基础上对荒漠生物结皮中藻类与苔藓植物的研究前景进行了展望,指出荒漠生物结皮中藻类与苔藓共生机理的探讨是未来的研究重点,这对进一步探明生物结皮中藻类和苔藓植物之间的相互作用,揭示它们的生态学关系具有重要的理论意义和实践价值。Algae and mosses are not only two common pioneer plants in the process of vegetation succession but also two groups with the highest biomass in the biological soil crust. As pioneer plants, algae and mosses are indispensable in the process of establishing the biological soil crust, which plays an important role in the desert ecosystem, namely, indicating vegetation type, soil holding, preventing from erosion by water or wind, and sand fixation. This paper reviews the recent research into algae and mosses which in arid and semi-arid areas and focuses on the ecological separate functions and relations of algae and mosses. Some suggestions are proposed for researching algae and mosses, especially research into the symbiotic mechanism of algae and mosses in the biological soil crust. Ecologically, such research has important significance and practice value for further analyzing the influence and demonstrating the ecological relations between algae and mosses.
