白马雪山曲宗贡地区9种群落类型中的大型真菌多样性研究

Study on the Macrofungi Diversity in 9 Communities of Quzonggong Area in Baima Snow Mountain

以白马雪山国家级自然保护区的重要组成区域曲宗贡地区为研究区域,以植物群落学为基础,较为细致地调查了该区域内9种群落类型中大型真菌的多样性状况.研究结果显示,大型真菌多样性状况为种类最多的是急尖长苞冷杉林,有80种以上;种类最少的是高山草甸及寒温性灌丛,仅有虫草1种;其余生态系统类型从多到少依次为黄背栎群落(25种),急尖长苞冷杉、黄背栎群落(23种),大果红杉、滇藏方枝柏群落(22种),亚高山草甸及寒温性灌丛(15种),滇藏方枝柏、大果红杉针叶群落(9种),大果红杉、急尖长苞冷杉群落(6种),黄背栎、大果红杉、急尖长苞冷杉、滇藏方枝柏混交林(4种).

Based on phytocoenology, the diversity of macrofungi in 9 communities of Quzonggong area, an important component region in Baima snow mountain national nature reserve was investigated in detail.The results showed that, the most abundant of macrofungi diversity was found in the communities dominated by single species of Abies georgei var.smithii with more than 80 species.The smallest species diversity of macrofungi was in alpine meadow and cold-temperate shrub with only 1 species of Cordyceps sinensis.The macrofungi diversity in other communities were that 25 species were found in communities dominated by Quercus pcuinosa.23 species were found in communities dominated by A.georgei var.smithii and Q.pannosa with 22 species were found in communities dominated by Larix potaninii var.australis and Sabina wallichiana.15 species were found in communities of subalpine meadow and cold-temperate shrub.9 species were found in communities dominated by S.wallichiana and L.potaninii var.australis.6 species were found in communities dominated by L.potaninii var.australis and A.georgei var.smithii.4 species were found in communities formed by Q.pannosa, L.potaninii var.australis, A.georgei var.smithii and S.wallichiana.
