百花山国家级自然保护区的大型真菌区系多样性

Study on macro fungi flora diversity in Baihua Mountain National Nature Reserve from Beijing of China

【目的】为了保护、开发和利用北京百花山国家级地区大型真菌资源。【方法】采用踏查法和样线法在百花山自然保护区大型真菌子实体发生期间进行野外调查。【结果】该区域共有大型真菌158种,隶属于26科63属,其中白蘑科Tricholomataceae、多孔菌科Polyporaceae、红菇科Russulaceae等5个科的物种数占比达62.7%,这些科的物种丰富度较高;红菇属Russula、蘑菇属Agaricus、杯伞属Clitocybe等9个属的物种占总物种数的42.41%,这些属的物种具有相对优势。大型真菌属的区系地理成分分析结果显示,该区域大型真菌世界分布属占67.16%、温带分布属占25.40%、亚热带-热带分布属仅为3.17%。【结论】百花山国家级自然保护区大型真菌分布为温带区系特征。

【Objective】The macro fungi flora diversity in Baihua Mountain National Nature Reserve from Beijing of China was statistically studied.【Methods】The investigation was carried out using the step-by-step method and the line-intercept method during the occurrence of macro fungi in Baihua Mountain National Nature Reserve.【Results】The macro fungi flora diversity in Baihua Mountain National Nature Reserve from Beijing of China was statistically studied.158 species of macro fungi were found in this region,which were of 26 families,63 genera.Tricholomataceae,Polyporaceae,Russulaceae,Boletaceae and Agaricaceae were the dominant families,which were comprised of 99 species and accounted for 62.7% of all species.Russula,Agaricus,Hygrophorus,Leccinum,Clitocybe,Marasmius,Suillus and Pholiota were the dominant genera that contained 67 species (42.41%).The phytogeographcial elements of the macro fungi flora covered cosmopolitan (67.16%),Temperate Zone (25.40%),Subtropical or Tropical(3.17%).【Conclusion】Cosmopolitan and Temperate Zone were two main distributional types of macro fungi flora in this region.
