摘要
为了解北盘江光照水库建成后对库区水域浮游动物产生的影响,于2009年9月至2010年5月,对北盘江光照水库浮游动物进行调查。结果显示:光照水库建库后有浮游动物4门87种,平均密度1 223.96ind/L,平均生物量0.751 7mg/L,分别是建库前的2.72倍、0.25倍和1.8倍。结论:与建库前自然河道相比,浮游动物在种群结构、密度和生物量方面均发生了较大变化。
To undstand the impact of Guangzhao reservior in Beipan river on zooplankton,researched the zooplankton in Guangzhao reservoir of Beipan River.from September 2009 to May 2010.The consequence showed that there were 4 phylum and 87 species in built Guangzhao reservoir,in which the average density was 1 223.96 ind/L,the average biomass was 0.751 7 mg/L.Moreover,the numerical value of the species,the average density and the average biomass in built reservoir were 2.71,0.25 and 1.8 times the values before the reservoir was built.Conclusion：Compared with the former condition,the average density,population structure,density and biomass of zooplankton in built reservoir had made great changes.
