青堆子湾池塘养殖区及邻近海域无机营养盐时空变化与富营养化风险
Temporal and Spait al Variation of the Inorgani c Nutrients and the Risk Assessment of Eutrophication inP ond Aquaculture Area and tI s Adjacent Sae Area of Qingdui zi Bay
摘要
Abstract
Objective] The aim was to study temporal and spatial variation of the inorganic nutrients in pond aquaculture area and its adjacent sea area of Qingduizi Bay,and evaluate its risk of eutrophication.[Method]Based on the investigation carried out in pond aquaculture area and its adjacent sea area of Qingduizi Bay from October 2011 to December 2012,a new classified model of eutrophication assessment was applied to e -valuate eutrophication levels in the study area.[Result] The average concentration of nutrient showed a significant seasonal variation.The spatial variations showed decreasing tendencies from the aquaculture area towards the outer sea .The temporal and spatial variations were affected by ter-rigenous sewage and aquaculture activities .The superficial seawater in Qingduizi Bay is at medium eutrophication level with nitrogen limitation during spring and summer and phosphorus limitation in winter .According to the assessment result,Qingduizi Bay is exposed to the danger of red tide.It is necessary to reinforce the management of pollutants discharged from "land sources".[Conclusion] The superficial seawater in pond aq-uaculture area and its adjacent sea area of Qingduizi Bay is at medium eutrophication level .关键词
