| 摘 要： | 基于2006年4月至2007年3月在浙江南麂海域的调查结果，对南麂海域塔玛亚历山大藻的种群动态及其与环境因子的关系进行了研究.结果表明：塔玛亚历山大藻在南麂海域仅出现在春季（4—6月）;藻细胞密度在春季呈规则的单峰曲线，表层水体中藻细胞密度的最高值（12250 cells·L-1）出现在5月8日;塔玛亚历山大藻集中出现在水温18.5 ℃～19.5℃、盐度29.5‰～31.0‰的水体中;较高的藻细胞密度与较低的磷酸盐浓度相对应，氮盐浓度的变化与藻细胞密度之间没有明显的对应关系.逐步线性回归结果表明，塔玛亚历山大藻细胞密度与N∶P存在显著的正相关关系. |

| Abstract: | Based on the investigation in Nanji Islands sea area of Zhejiang Province from A pril 2006 to March 2007, the dynamics of Alexandrium tamarense and its relations with environmental factors were studied. In the study sea area, A. tamarense cells could only be found in spring (from April to June), and t he cell abundance was of single peak curve, with the highest (12250 cells·L -1) in surface water on 8th of May. Higher cell abundance of A. tamarense was found at the water temperature of 185 ℃〖KG-*4〗-〖KG-*7〗195 ℃, salin ity of 295‰〖KG-*4〗-〖KG-*7〗310‰, and lower PO4-P concentration, but no correlation was observed between A. tamarense cell abundance and water d issolved inorganic N concentration. Linear stepwise regression revealed that the re was a significant positive correlation between the cell abundance of A. tamarense and the ratio of water dissolved inorganic N to PO4-P. |
