哈素海与乌梁素海浮游植物与环境关系研究

于2009年4月至2011年9月对内蒙古哈素海和乌梁素海的浮游植物多样性进行调查,并对其浮游植物多样性及环境因子进行分析.结果表明:哈素海浮游植物均匀度与湖水的离子系数、钙镁比值均呈现出高度的正相关性；多样性指数、丰度指数则与湖水的总硬度、离子系数、碱度之间呈负相关.乌粱素海浮游植物多样性指数、均匀度、丰度指数与湖水的钙镁比值、离子系数、总硬度呈高度相关.

Relationship of Hasuhai and Wuliangsuhai phytoplankton community with environment

From April 2009 to September 2011, we conducted a survey of phytoplankton diversity in the lakes Hasuhai and the Wuliangsuhai of Inner Mongolia, and also analysed the relationship between phytoplankton diversity and environmental factors. Using the Shannon-Weaver diversity index, the Margalef abundance, Pielou evenness calculated and SAS9.0 Software to analyse data.The results showed that Hasuhai phytoplankton evenness index showed a high degree of positive correlation with the ion coefficient, calcium and magnesium ratio; abundance index, the diversity index showed a negative correlation between them and the ion coefficient, alkalinity, total hardness. Wuliangsuhai phytoplankton evenness, diversity index and the abundance index showed a high degree of correlation with the ion coefficient, calcium and magnesium ratio and total hardness.
