%X 湖泊在高原生态系统中具有重要地位&#65292;然而湖泊也面临诸多挑战&#65292;如水质下降、重金属污染、生态退化等。湖泊以及其水体内的物种组成能够记录区域环境变化并调节区域气候。浮游植物是湖泊重要的初级生产者&#65292;其群落构建是反映湖泊污染水平和生态系统特征的可靠指标。硅藻作为浮游植物的重要组成&#65292;对营养盐、重金属、水温等环境变化极为敏感&#65292;其物种群落组成和多样性在环境因子影响下的季节变化模式&#65292;是开展湖泊生态健康和环境质量评价的重要内容。因此了解硅藻在不同环境因子影响下的变化模式和指示意义是进行不同水环境梯度下物种变化特征的响应监测的重要环节&#65292;可以为湖泊水体生态环境保护提供理论支持&#65292;从而有助于更加精准地探究湖泊生态系统的动态变化规律。 <br>Lakes play a crucial role in plateau ecosystems, yet they face multiple challenges such as declining water quality, heavy metal pollution, and ecological degradation. Lakes and their aquatic species composition not only document regional environmental changes but also regulate local climate. As key primary producers in lakes, phytoplankton exhibit community assembly patterns that serve as reliable indicators of pollution levels and ecosystem characteristics. Diatoms, being vital components of phytoplankton, demonstrate high sensitivity to environmental variations including nutrient concentrations, heavy metals, and water temperature. The seasonal dynamics of diatom community structure and species diversity under environmental influences constitute essential content for evaluating lake ecological health and environmental quality. Understanding the response patterns and ecological indications of diatoms under different environmental factors represents a critical step in monitoring species variation across water environmental gradients. This knowledge provides theoretical support for lake ecological protection and facilitates precise exploration of dynamic changes in lake ecosystems.
