贵州红枫湖越冬藻类的空间分布与实验室复苏实验
Spatial distribution and recruitment simulation test of over-winter algae in Lake Hongfeng,Guizhou
摘要
Abstract
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.关键词
