摘要

摘要: 于2013年3-5月通过走航取样分别对巽他陆架和马六甲海峡表层海水浮游植物叶绿素a生物量和群落结构进行了观测和研究.结果表明:巽他陆架生物量较低,叶绿素a浓度平均值为(0.083±0.043)μg/L,爪哇海的SS4站位生物量最低,仅为0.014 μg/L,浮游植物粒级组成上主要以Pico-级为优势,占80%以上;马六甲海峡自西北至东南存在明显的盐度梯度,在盐度最低的SM5站,叶绿素a生物量最高,达到1.080 μg/L;马六甲海峡站位叶绿素a浓度平均值为(0.433±0.315)μg/L,同时浮游植物群落结构变动较大.在海峡西北的SM1-SM4站与巽他海峡类似,主要以聚球藻为优势类群,Pico-级浮游植物占60%~80%;在生物量最高的SM5站,同样以聚球藻为优势类群,而在海峡东南段的SM6和SM7站,虽然叶绿素a浓度相对于SM5略有降低,但仍明显高于其他马六甲海峡站位和巽他陆架站位,此两个站位硅藻比例明显升高,均可达20%以上.从优势类群生物量与环境因子和营养浓度的相关性可以看出,研究海区叶绿素a生物量与水体盐度呈现显著负相关 (p<0.050),说明陆源输入对研究海区生物量具有明显的影响.另外,硅藻生物量也与磷酸盐浓度 (p<0.050) 和硅酸盐 (p<0.010) 浓度均呈现显著正相关;聚球藻在浮游植物群落中的优势度会受到陆源营养盐输入的影响而降低,但仍然是整个研究区域最优势的浮游植物类群.

Abstract: Surface water samples were collected in order to study the spatial distribution of phytoplankton community in the Sunda Shelf and the Strait of Malacca during March and May 2013. Significant spatial variations of phytoplankton total Chl a(TChl a) biomass and community structure were observed using the photosynthetic pigments method. The TChl a biomass was low to some extent in the Sunda Shelf during the intermonsoon season, when and where the minimum value was only 0.014 μg/L at Sta. SS4 in the Java Sea, and the average was (0.083±0.043) μg/L in the Sunda Shelf. The picophytoplankton dominated in the Sunda Shelf and contributed more than 80% of the total biomass. The salinity gradient was distinct along the Strait of Malacca from northwest to the southeast. And the lowest salinity appeared at Sta. SM5 with the highest TChl a concentration (1.080 μg/L), which was outstanding from the average value of all the strait stations . The Synechococcus dominated 60%-80% of the total phytoplankton biomass at the stations in the Sunda Shelf and SM1-SM4. Even though the TChl a concentrations was less than it at Sta. SM5, they were still apparently higher at Sta. SM6 and SM7 than the biomass at the other stations. And the Diatoms contributed more than 20% at these two stations as a result of the higher nutrient concentration carrying by the river runoff, especially for phosphate and silicate. On the contrary, the superiority of Synechococcus might be weakened by the intrusion of low-salinity, high-nutrients water.
