摘　　要：对贵定野生大鲵自然生态保护区内王寨河6个断面不同季节浮游藻类的种类、密度进行了调查,并采用Margalef和Shannon-wiener多样性指数进行了水质评价。结果表明,王寨河春季有浮游藻类5门83种,秋季有4门66种。王寨河水质总体上清洁,有利于大鲵(Andrias davidianus)野生种群的栖息生存。Wangzhai river is located in the Guiding Ecological Reserve for the wild population of Andrias davidianus, Guiding, Guizhou province. The species and density of pelagic algae were surveyed at 6 sampling sites in Autumn, 2007and Spring, 2008, and the water quality in the river was also evaluated according to both the Margalef and Shannon-wiener indices of algae. Totally 83 species of pelagic algae were found in Wangzhai river in Spring, and in autumn, 66 species. Most of these species are diatom, accounting for 65% of total species in spring and 70% in autumn. The density of pelagic algae ranged from 2.83 × 10^5 ind./L to 6.92 × 10^5 ind./L, with an average of 5.34 × 10^5 ind./L, in spring. In autumn, the range and average were 4.5 × 10^4 - 1.8 × 10^5 ind./L and 9. 908 × 10^4 ind./L, respectively. Margalef index ranged from 3.06 to 5.90 with an average of 4.56 in spring, and from 2.31 to 6.63 with an average of 4.10 in autumn. Shannon-wiener index ranged from 3.57 to d. 16 with an average of 3.89 in spring and from 2.79 to 4.54 with an average of 3.52 in autumn. In general, the water in the river is clean and suitable to the wild population of Andrias davidianus in the reserve.
