%X 淮南高塘湖是一个重要的湖泊生态系统，轮虫作为该水体的关键生物群体，对湖泊的生态平衡和水质健康具有重要意义。本研究通过对高塘湖轮虫群落结构的定期监测，系统分析了其季节变化特征。研究结果表明，高塘湖轮虫群落具有显著的季节变化。春季，轮虫群落以种类多、密度高为特征，以温水轮虫类为主导。夏季，由于水温升高，温水轮虫类继续保持多样性，同时富营养水体中出现了一些耐富营养的种类。秋季，水温逐渐下降，富营养水体中的轮虫密度减小，而耐富营养种类逐渐占主导地位。冬季，水温降至最低，轮虫群落整体数量减少，以富营养水体中的一些抗寒种类为主。此外，季节变化还影响了轮虫群落的生命周期和繁殖策略。春季和夏季是轮虫繁殖高峰期，而秋季和冬季则呈现相对较低的繁殖活动。这种季节变化与水体环境因子(如温度、营养盐浓度等)的周期性变化密切相关。综合而言，淮南高塘湖轮虫群落结构在季节尺度上呈现明显的变化，这为深入理解湖泊生态系统的季节动态、环境响应机制以及水质健康状况提供了有益的信息。<br />
Huainan Gaotang Lake is an important lake ecosystem, where rotifers play a crucial role as a key biological community, contributing significantly to the ecological balance and water quality health of the lake. This study systematically analyzed the seasonal variations in the rotifer community structure through regular monitoring of Gaotang Lake. The results indicate significant seasonal changes in the rotifer community. In spring, the community is characterized by high species diver-sity and density, with dominance of warm-water rotifer species. As temperatures rise in summer, warm-water rotifer species maintain diversity, and some nutrient-tolerant species appear in eu-trophic waters. In autumn, with decreasing temperatures, the density of rotifers in nutrient-rich waters decreases, while nutrient-tolerant species gradually dominate. In winter, as temperatures drop to the lowest, the overall abundance of the rotifer community decreases, with cold-resistant species prevailing in eutrophic waters. Additionally, seasonal variations influence the life cycle and reproductive strategies of the rotifer community. Spring and summer are peak breeding seasons, while autumn and winter exhibit relatively lower reproductive activity. These seasonal changes are closely related to periodic variations in environmental factors such as temperature and nutrient salt concentration. In summary, the rotifer community structure in Huainan Gaotang Lake exhibits significant seasonal variations, providing valuable information for a deeper understanding of the seasonal dynamics, environmental response mechanisms, and water quality health of lake ecosystems.
