Distribution of chlorophyll-a and primary productivity in Yantai Sishili Bay
摘要
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 i-tems 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 a-mong 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.关键词
