兼性塘试验中浮游植物群落结构与水质关系的研究

Research on Relationship between Community Structure of Phytoplankton and Water Quality in Facultative Pond

本文讨论了兼性塘试验中浮游植物群落结构与水质的关系。结果表明:浮游植物群落的多样性指数(H′)与塘的有机负荷率、出水BOD_5和COD均呈负相关;在温度不变时,浮游植物群落的生态优势度与塘的有机负荷率呈正相关(r>0.90)。

The relationship between community structure and water quality in facultative pond was studied. The results showed that diversity index (H') of phytoplankton community and the organic loading rate, effluent BOD_5 and COD of facultative experimental ponds were negatively relative. When the temperature was constant, the ecological dominance was positively relative to organic loading rate (r>0.90)
