福建红树林区海藻的分布及季节变化
Distribution and seasonal change of algae in Fujian mangrove areas
-
摘要: 主要研究了福建省3个红树林区的海藻不同滩面分布的情况、海藻种类组成的季节变化以及不同季节的海藻群落类型.研究表明:(1)福建红树林区海藻在不同滩面分布表现出,红藻较喜荫蔽潮湿的环境,而绿藻适生在光照条件较好生境.(2)由福建红树林区各门海藻种类组成的季节变化来看,蓝藻种数在一年四季没有明显变化规律,红藻四季种数变化幅度不大,而绿藻在不同季节种数有明显变化,春季种数最多,进入夏季后种数逐渐减少,到秋、冬季后种数又开始上升,到第2年春季又达到最多.(3)不同季节福建红树林区海藻群落类型中,优势种主要是红藻,以及一些绿藻.Abstract: The distribution of algae in different mudfalt,seasonal changes of algae species composition and community type of algae in Fujian mangrove areas throug hout the year in 1990 are mainly dealt with.The results are shown as follows:(1)In different intertidal mudfalt,the distribution of algae in Fujian mangrove areas shows that Rhodophyta species appropriated to the shade and damp habitat,and Chlorophyta species to sunshine habitat. (2)The seasonal changes in species number of blue-green algae are undefined,the number of red algae is relatively stable throughout the year,green algae number changes with season,the highest is found in spring,gradually reduces in summer,but increases again from autumn to winter.(3)From the algae communities of four seasons in Fujian mangrove areas,the dominant species of algae are mainly Rhodophyta and some Chlorophyta.
