贵州岩下大鲵自然保护区藻类生态分布

Eco-distribution of the algae in Yanxia Andrias Davidianus nature reserve of guizhou province

通过对贵州岩下大鲵自然保护区藻类的生态分布情况进行调查,并且利用植物区系丰富性综合系数法对保护区内藻类植物的丰富性进行了评价。结果表明,绿藻和硅藻为保护区内优势种群,水塘和静水河中物种最丰富,该保护区内藻类的物种组成具有亚热带区系性质的特点,藻类丰富性相对贫乏。

In this paper,the algae eco -distribution of Yanxia Andrias davidianus nature reserve of Guizhou was studied, and the plant species richness of nature re＇serve＇s algae was evaluated by the abundant flora of integrated coefficient method. The results show that Chlorophyta and Bacillariophyta are the dominant groups in the nature reserve. Ponds and still water river have the richest species. The algae, in this area, has subtropical characteristics and lack of richness relatively.
