摘    要:2006~2010年5、8、10月,分别对烟台四十里湾近岸水域进行了30航次的综合调查,调查内容包括海水水质、浮游植物、叶绿素以及水文气象等要素。四十里湾近岸水域表层叶绿素a和初级生产力的季节与年际变化结果显示,浮游植物数量、叶绿素a含量和初级生产力一般在8月出现高值;仅2008年浮游植物数量最高值出现在10月,2009年叶绿素a含量和初级生产力最高值出现在5月。2008年10月浮游植物数量平均值为所有航次中最高,达到51.61×104cells/L,且各站位间差别显著(P<0.01);2007年10月最低,仅为0.02×104cells/L。2006~2009年,表层叶绿素a含量和初级生产力均值呈逐年增加趋势,2009年分别达到8.72μg/L和1481.42mg/m3·d;2010年(叶绿素a:6.13μg/L;初级生产力:733.91mg/m3·d)又降至与2008年相当。近5年,四十里湾浮游植物数量、叶绿素a含量和初级生产力均呈现湾东部高于西部的趋势,初级生产力与表层叶绿素a含量呈强正相关关系(R=0.921,P<0.01),并得出二者的回归方程式,这为海洋初级生产力的估算与评价提供了一种更简便的方法。

关 键 词:四十里湾  浮游植物数量  叶绿素-a  初级生产力  相关性

Abstract:In May, August and October 2006~2010, thirty integrated surveys of coastal water environment were carried out in Yantai Sishili Bay (YSB) twice per month. Mornitored items included water quality, phytoplankton, surface chlorophyll-a and hydrometeorology. The spacial and temporal distribution of chlorophyll-a and primary productivity in YSB was studied. The results showed that phytoplankton density, chlorophyll-a concentration and primary productivity were generally higher in August; But in 2008,the maximum of phytoplankton density appeared in October, and in 2009 the maximums of both chlorophyll-a concentration and primary productivity appeared in May. In October 2008, the phytoplankton density, the highest during the survey period, reached 51.61×104 cells/L, and significant differences were found among all six sampling sites(P<0.01); The lowest value (0.02×104 cells/L) appeared in October 2007. From 2006 to 2009 both chlorophyll-a concentration and primary productivity showed a growing trend, but in 2010 they decreased to a similar level as 2008. In the last five years,phytoplankton density, chlorophyll-a concentration and primary productivity were generally higher in east YSB than in the west. Furthermore, a significant positive correlation was found between primary productivity and chlorophyll-a concentration (R=0.921,P<0.01), and a regression equation was developed. It will offer an option to estimate and assess the primary productivity of the coastal waters.
Keywords:Sishili Bay Phytoplankton density Chlorophyll a concentration Primary productivity Correlation
