内蒙古盐沼浮游动物多样性指数与环境关系研究

Study on the relationship between zooplankton diversity index and environmental factors in the salina wetland in Inner Mongolia

连续多年对内蒙古沙漠盐沼的桃力庙-阿拉善湾海子和红碱淖尔湖泊浮游动物多样性与环境因子关系进行调查研究。浮游动物调查方法依据《内陆水域渔业自然资源调查手册》进行;多样性评价采用均匀度、丰度和多样性指数计算;与环境相关性采用SAS9.0软件分析。结果表明:在内蒙古沙漠盐沼湿地,Ca2+/Mg2+值、离子系数(M/D)、总硬度与浮游动物多样性指数显著相关,是重要的生态指标,是浮游动物多样性及生态分布的限制因子。

We researched the relationship between zooplankton diversity index and environental facfors of Taolimiao-alasanwan Haizi and Hongjiannao Lake in Inner Mongolia desert for many years. The zooplankton investigation based on （the inland waters fisheries resources investigation handbook）. The diversity was evaluated by uniformity, abundance and diversity index. The correlation was analysed by SAS9.0 software. The results showed that there was a significant correlation between the zooplankton diversity index and the environment factors including the ratio of calcium and magnesium, the ion coefficient （M/D）, total hardness. These faefors were important ecological indicators, were the limiting factors to the zooplankton diversity and ecological distribution.
