该文依据 1995年 3月～ 1996年 1月间浮游植物的调查资料 ,并结合同期水温和营养盐的资料变化 ,分析不同环境因素对浮游植物群落结构的影响。结果表明 :水温的变化对浮游植物的种类组成和数量变化都有一定影响 ,秋季和冬季优势种交替明显 ;营养盐对浮游植物群落结构的变化影响明显。根据胶州湾营养盐结构的改变状况 ,并结合历史资料对比发现 ,胶州湾网采浮游植物的物种数和细胞数量呈下降趋势 ,优势种类趋单一化 ;但初级生产力并未下降 ,可能与微型浮游植物所占份额增大相关。
Based on the survey data of phytoplankton from March 1995 to January 1996 and the changes of water temperature and nutrients during the same period, the paper analyzes the effects of different environmental factors on the phytoplankton community structure. The results showed that: the change of water temperature had certain influence on the species composition and quantity of phytoplankton, the alternation of dominant species in autumn and winter; and the effect of nutrients on the change of phytoplankton community structure. According to the change of nutrient structure in Jiaozhou Bay and the comparison of historical data, it was found that the number of phytoplankton species and cell number in Jiaozhou Bay decreased and the dominant species tended to be single. However, the primary productivity did not decrease, Increased share of plants related.
