淀山湖叶绿素a分布特征及其与浮游植物密度的相关性
Distribution characteristics of chlorophyll a and its relationship with phytoplankton density in Lake Dianshan
摘要
Abstract
This paper reported the horizontal and temporal distribution pattern of chlorophyll a and phytoplankton density as well as their relationships, which were based on the ecology investigation carried out in Lake Dianshan from October 2009 to September 2010. The results showed that: (1) The chlorophyll a concentration was rangedfrom 0. 87 to 139. 43 mg/m3 with a mean of (25. 35 ± 2. 71) mg/m3; (2) The phytoplankton density was ranged from 0. 40 to 210. 91 × 106 ind/L with a mean of (10. 02 ± 2. 45) × 106 ind/L; (3) In the temporal scale, both chlorophyll a and phytoplankton density were higher in spring and summer and lower in autumn and winter. In the horizontal scale, they were higher in northern sites than in southern sites; (4)Correlation analysis showed that chlorophyll a and phytoplankton density were significantly correlated (Sig. ≤0. 01), and Chlorophyta, Cyanophyta, Bacillariophyta and Cryptophyta s densities' contributions to chlorophyll a concentration were higher than other categories. And the contributions varied with seasons.关键词
