摘要： 2021年3月对安徽省宁国市枫香林（Liquidambar formosana）、青冈栎林（Cyclobalanopsis glauca）、马尾松林（Pinus massoniana）和杉木林（Cunninghamia lanceolata）土壤藻和树生藻种类组成特征进行调查，研究气生藻丰富度与环境因子的关系。结果显示：表层土壤和树皮上共检出藻类83种，隶属5门7纲21目35科45属，以绿藻、蓝藻居多。土壤藻种类丰富度明显高于树皮，22种藻类在两种基质上均存在。土壤藻优势科为绿藻门丝藻科，树皮藻优势科为蓝藻门色球藻科。土壤藻丰富度表现为青冈栎林>枫香林>杉木林>马尾松林，影响其丰富度最显著的环境因子为土壤氨态氮、有机质（P<0.05）。树皮藻丰富度表现为马尾松林>青冈栎林>杉木林>枫香林，其丰富度受表层树皮总氮、总磷、总钾影响不明显。

Abstract: The species composition of soil algae and corticolous algae of Liquidambar formosana, Cyclobalanopsis glauca, Pinus massoniana and Cunninghamia lanceolata in Ningguo city, Anhui Province was conducted in March 2021, the richness of aerial algae and its relationships with environmental factors were analyzed. The results showed that a total of 83 species of algae were detected in the surface soil and bark, belonging to 5 phyla, 7 classes, 21 orders, 35 families, 45 genera, dominated by Cyanophyta，Chlorophyta respectively. The richness of aerial algae in different attachment substrates was soil >bark, 22 species were present on both substrates. The dominant families of soil algae and corticolous algae were Ulotrichaceae of Chlorophyta and Chroococcaceae of Cyanophyta, respectively. The richness of soil algae was as follows, Cyclobalanopsis glauca > Liquidambar formosana > Cunninghamia lanceolata > Pinus massoniana, and the most significant correlation factors affecting its richness were ammonia nitrogen and organic matter (P<0.05). The richness of corticolous algae was as follows, Pinus massoniana > Cyclobalanopsis glauca > Cunninghamia lanceolata > Liquidambar formosana, and was not significantly affected by surface bark nutrients.

Key words: aerial algae, forest, soil algae, corticolous algae
