粤西近岸海域浮游植物群落的生态特征
Ecological characteristics of the phytoplankton community structure in the West Guangdong coastal area
摘要
Abstract
Based on data collected during an ecological investigation of West Guangdong before 30 meters coastal waters during a wet (September 2011) and a dry season (January 2012), the species composition, dominant species, abundance, and community diversity of phytoplankton were analyzed. A total of 116 species consisting of 41 genera belonging to 4 phyla were identified. Diatom was the predominant phyla group. Forty common species occurred in both wet and dry seasons, with a species similarity index between the two seasons of 34.48% suggesting significant seasonal variation in the species composition. Only one dominant species occurred during the dry season,Phaeo-cystis globosa, with a dominance of 0.496. During the wet season, there were four dominant species, the main one wasChaetoceros curvisetus with a dominance of 0.249. Phytoplankton abundance showed significant seasonal and regional differences and was higher in inshore waters than in offshore. During the wet season, the phytoplankton abundance in the Zhanjiang coastal waters was the highest. During the dry season, phytoplankton abundance de-creased from the southwest to northeast coastal waters. In general, the phytoplankton abundance during the dry season was higher than during the wet season. Community diversity indexes in the southwest waters during dry season were obviously lower than those in the northeast waters. Diversity indexes during the wet season were rela-tively higher than during the dry season, but there were no significant differences in diversity during the wet season. Correlation analysis demonstrated that the phytoplankton abundance was positively correlated to pH and suspended solids (SS), and negatively correlated to water temperature during the wet season and salinity during the dry season.关键词
