摘要
2008年3月～2009年1月调查了流沙湾潮间带及湾内(109°55'～109°59'E,20?22'～20°28'N)底栖大型海藻资源,定性、定量分析该海湾底栖大型海藻种类、生态分布、区系性质、群落结构及生物量的季节变化规律。共采集底栖大型海藻3门10目17科19属32种,其中红藻门4目9科9属15种,绿藻门4目6科7属14种,褐藻门2目2科3属3种,以亚热带藻种占绝对优势,达59.4%,温带成分21.9%,热带成分18.7%。采样海藻具印度-西太平洋海洋植物区系中国-日本亚热带海洋植物亚区特点。调查区域内底栖大型海藻群落组成的季节变化明显。
The macroalgae species, ecological distribution, the floral texture, community structure and the seasonal biomass variations in Liusha Gulf are investigated, based on qualitative and quantitative survey data of benthic marine macroalgae of intertidal zone and benthos belt in Liusha Gulf（109°55′-109°59′E,20°22′-20°28′N） in the period of March in 2008 to January in 2009.3 Division 10 Order 17 Family 19 Genus 32 species of benthic marine macroalgae in Liusha Gulf are reported, including 4 Order 9 Family 9 Genus 15 species of Rhodophyta, 4 Order 6 Family 7 Genus 14 species of Chlorophyta, 2 Order 2 Family 3 Genus 3 species of Phaeophytin.The principal geographical group of this flora is subtropic species, constituting 59.4% of the total, and the temperate species occupies 21.9%, and the tropic species occupies 18.7%. The marine floral texture of Liusha Gulf belongs to China-Japan subtropical areas of marine plants of India - western Pacific Ocean flora. The seasonal variation of benthic seaweed community are very obvious.
