1992年2月和8月作者在浙江象山港对海洋微微型光能自养原核生物——蓝细菌Synechococcus和微微型光能自养真核生物的丰度与分布、环境制约、时空变化及蓝细菌种群的表观增长率进行了观测研究.结果表明,这两类微微型光能自养生物的细胞丰度均为夏季（蓝细菌丰度平均为3.29×103cell/cm3,真核生物平均为1.61×103cell/cm3）高于冬季（蓝细菌平均丰度为1.23×103cell/cm3,真核生物为0.37×103cell/cm3）.冬季蓝细菌丰度港口部低于港中、顶部,而真核生物丰度的空间分布则相反;夏季两类生物细胞丰度在港口部与港中、顶部相近.周日连续观测表明,细胞丰度的周日变化与潮汐和悬浮体浓度明显相关.表观增长率夏季高于冬季.实验表明,水温、悬浮体浓度和光的可利用率是制约这两类微微型光能自养生物的主要因子.
In February and August 1992, the authors reported the abundance and distribution of marine pico-type phototrophic prokaryotes Synechococcus and pico-light autotrophic eukaryotes at Xiangshan Harbor, Zhejiang Province, China. Environmental constraints, temporal and spatial variations, and blue The results showed that the cell abundance of these two kinds of pico-light autotrophs were all in summer (the average cyanobacteria abundance was 3.29 × 103cell / cm3, the average of eukaryotes was 1.61 × 103cell / cm3) was higher than in winter (average cyanobacteria abundance was 1.23 × 103cell / cm3, and eukaryotes was 0.37 × 103cell / cm3) .In winter, The abundance of biological abundance was oppositely distributed in summer, while the abundance of two kinds of biological cells in summer was near the port and the top of the harbor.The continuous observation on Sunday showed that the variation of cell abundance was significantly correlated with the concentration of tide and suspension. The growth rate is higher in summer than in winter. Experiments show that the water temperature, the concentration of suspended solids and the availability of light are the main factors restricting these two types of pico-light autotrophic organisms.
