英文摘要	To better understand the distribution and annual variation of nutrients in the Laizhou Bay, a successive survey about dissolved inorganic nitrogen (DIN), phosphate(PO_4-P) and silicate(SiO_3-Si) from 2004 to 2014 was conducted. In the present study, high concentrations of DIN, PO_4-P and SiO_3-Si were located at the southwest coast of the Laizhou Bay, especially at Xiaoqing River estuary and its vicinity. The spatial distributions of nutrients in the Laizhou Bay were mainly influenced by the terrestrial inputs such as Xiaoqing River and itsvicinity. Although, DIN concentrations in the Laizhou Bay from 2004 to 2014 were higher with medians ranging from 8.14 μmol/L to 53.98 μmol/Lthan those in the 80 s and 90 s of the 20th century, anannual variation trend of slight decreased from 2004 to 2014 was shown in the Laizhou Bay. The nitrate was the main form of DIN contributing 83 %, while nitrite and ammonium salt contributing 7 % and 10 %, respectively. Low concentrations of PO_4-P in the Laizhou Bay were observed with medians ranging from 0.03 μmol/L to 0.49 μmol/L with an obvious annual variation trend of decrease. The medians of SiO_3-Si in the Laizhou Bay ranged from 8.5 μmol/L to 52.9 μmol/L with a decrease annual variation trend in August. The temporal distributions of nutrients in the Laizhou Bay were mainly influenced by the nutrients fluxes of Xiaoqinghe River. The medians variation of DIN/PO_4、SiO_3 /DIN and SiO_3 /PO_4 were 78.9~1112.4, 0.2~2.2 and 40.2~442.5, respectively. The annual variation trends of increase for DIN/PO_4 and SiO_3 /PO_4 while no obvious annual variation trend for SiO_3 /DIN were observed from 2004 to 2014. The analysis on nutrient structure indicated that PO_4-P was absolute limitation with the trend of increase while SiO_3-Si was the limitation in May. The nutrient levels of the Laizhou Bay shifted from oligotrophy in the 80 s and 90 s of the 20th century to potential eutrophication of phosphorus limitation during 2004-2014.
