贵州雷公山国家级自然保护区藻类植物区系研究

Algae flora of Leigong Mountain Nature Reserve of Guizhou

在野外调查与室内分类研究的基础上,首次对雷公山自然保护区藻类植物进行了区系分析。结果表明:该区有藻类植物432种(含54个变种和2个变型),隶属于6门8纲24目45科96属。其区系成分以国内外广泛分布为主,占总种数的38.44%,还出现热带种类和高海拔高纬度冷水性种类。此外,属和种的相似性系数比较反映了分类级别越高,其相似性就越大。

Based on the investigation and data access through inside,the floristic analysis of algae Leigong Mountain Nature Reserve was studied for the first time.The results indicated that in this area there were 432 species （including 54 varieties and 2 forms）belonging to 96 genera 45 families 24 orders 8 classes and 6 divisions.The total elements were ahead by widely distributed both at home and abroad types representing 38.44% of the entire species,followed by the element of high altitude and latitude is that living in cold water,as well as Tropical element.In addition,the similarity of genus and species reflected higher level of the classification,the greater the similarity.
