本文选取贵州省红枫湖这一典型的亚深水型湖泊作为研究对象,在8个代表性湖区开展了为期一年的表层水体藻类浮游植物分布的月定量监测,并在4个采样点采集新鲜沉积物进行了越冬藻类赋存与复苏模拟实验研究.研究表明,红枫湖表层水体藻类种群密度蓝藻绿藻>硅藻>甲藻,蓝藻为优势门类,水体藻类种群密度秋季初期最高,其次是春季初期和夏季,具有明显的季节性演化特征.水体中越冬藻类以蓝藻为主,其次是硅藻和绿藻,水深对水体中藻类的种群密度及组成没有显著影响.沉积物中越冬藻类以硅藻为主,基本不含蓝藻.模拟实验表明,水体中的光照条件对藻类的复苏和生长有重要影响,温度和沉积物中藻类的种群密度与组成同样影响藻类的复苏. |

In order to investigate the spatial variations of the over-winter algae in different areas of Lake Hongfeng, sediment and water samples were collected monthly at 8 sites over a period of 1 year. Simulation test of dormancy algae recruitment from sediments collected form 4 sites were carried out. The results showed that cyanobacteria were the dominant species in surface water, and the population density of the cyanobacteria was significantly higher than the green algae, diatoms and dinoflagellates. Algal population density evolved seasonally, which was the highest in early autumn and followed by the early spring and summer. Cyanobacteria dominated in over-winter algae in water, followed by diatoms and green algae. The water depth did not affect significantly the population density and composition of the algae in water. Differing from in water, over-winter algae in sediments were mostly diatoms, and only small amount of cyanobacteria were found. Simulation experiments showed that light intensity had a major impact on the algae recruitment, which was also affected by water temperature and sediment algae population density. |
