硇洲岛春季底栖海藻资源

2003—2005年的3—5月，对硇洲岛有代表性的大浪、谭井、存亮潮间带进行底栖海藻资源调查。分析了各地区春季不同月份藻类的种群结构和平均生物量变化，总结了各藻的生态分布区域。共得定性标本56属87种，其中蓝藻类3属4种，绿藻类14属27种，红藻类32属44种，褐藻类7属12种。其中谭井的种类最多，其次是大浪，存亮的最少。各地均以红藻为主，其次是绿藻、褐藻，蓝藻最少。种类的数量和分布具有月份上的差异。各地的平均生物量3月份以谭井的最多，4月份大浪的最多，5月份存亮的最多。潮间带海藻的生态分布区以中、低潮带为主。

Resources of benthic algae from intertidal zone on Naozhou Island in spring

The survey on the resources of benthic algae was carried out in Naozhoudao in spring from 2003 to 2005.The composition and biomass of them were studied,and the ecological distribution sections of every alga were summarized.The results are as follows:1.56 genera,87 species of them were found.They are identified as: 3 genus,4 species in Cyanophyta;14 genera,27 species in Chlorophyta,32 genera,44 species in Rhodophyta,7 genera,12 species in Phaeophyta.2.The number of species in Tanjing was the most.3.The quantity and distributing of species among months were different.4.On the average biomass in Tanjing was the most in Mar.;Dalang was the most in Apr.,and Cunliang was the most in May.5.The algae were chiefly distributed in middle intertidal zone and lower intertidal zone.
