中文摘要	浮游植物功能群在水生态系统中意义重大,能够生产氧气并为其他生物提供食物,维持其他生命的生存,进而保证水生态系统的平衡。目前,针对寒冷干旱地区浮游植物功能群与生境间关系的研究鲜见报道,本文以内蒙古典型的寒旱区湖泊乌梁素海为研究对象,为探究其浮游植物功能群特征及与环境因子的响应关系,于2011年6月─2013年8月间的不同季节对浮游植物进行了采样、测试,使用Excel和物种-环境因子关系双序图进行了分析。结果表明,乌梁素海共有23个常见功能群,每个功能群均具有代表种及其适应的生境环境特征。C、MP、W1、X2是湖区出现频率最高,生物量比重最大的优势功能群。C、MP全年均占优,且在温度较低的冬季、春季以及秋季比例较大。L0、J在春、夏季占优势。TC在夏季占优, X2在秋季、冬季占优,W1在冬季的比重较大。功能群组成具有明显的空间差异,功能群类型呈现湖区中部>湖区南部>湖区入口的规律。冗余直接梯度分析表明,功能群组与环境因子的相关性均在0.9以上,且功能群组与环境因子的累计方差为83.6%,湖区水深、温度、pH、总磷等环境因子是浮游植物功能群季节演替的主要驱动因子。结合乌梁素海实际环境特征,将功能群分为三大群落,分别为浅水区高盐度的功能群S1、MP、W1、C,高温深水低营养盐功能群P、L0、X1、F、J以及低温高营养盐功能群X2、TC、Y。
英文摘要	Phytoplankton functional groups plays an important role in aquatic ecosystems. Phytoplankton can produce oxygen and food, which sustain all other life forms, ensuring aquatic ecological balance. Information about phytoplankton functional groups related to environmental conditions in Cold and Arid Regions is little. Wuliangsuhai Lake is located in cold and arid regions of Inner Mongolia and is a typical grass algae lake. To explore the characteristics of phytoplankton functional groups related to environmental conditions, phytoplankton were collected and analyzed from June 2011 to August 2013, and they were analyzed using Excel and species-environmental factors biplot. The results showed that twenty-three common functional groups were found in Wuliangsuhai Lake. In the above function group C, MP, W1 and X2 appeared the most frequent, and had the largest proportion in dominant functional groups. C and MP were the dominant species in the whole year, especially in the relatively low temperature winter, as well as spring and autumn. L0 and J were the dominant species in spring and summer. TC was the dominant species in summer. X2 was the dominant species in autumn and winter. W1 hold a large proportion in winter. Functional groups had significant spatial differences. The spatial variance of functional groups was central lakes > southern lakes > lakes entrance. Redundancy analysis showed that correlation between phytoplankton functional groups and environmental factors were more than 0.9, cumulative variance of species and environmental variables is 83.6%. Lake water depth, temperature, pH and other environmental factors were the main driving factors on seasonal dynamics of phytoplankton functional groups. Combined with the actual environmental characteristics in Wuliangsuhai Lake, functional groups were divided into three categories and respectively as shown below:Functional groups were S1, MP, W1 and C which located in shallow water with high salinity. Functional groups were P, L0, X1, F and J which located in high temperature deepwater with low-nutrient. Functional groups were X2, TC and Y which is located in low temperature water with high nutrient.
