青堆子湾养殖池塘与临近海域悬浮颗粒物的平面分布与季节变化

Horizontal Distribution and Seasonal Change of Particulate Matter in Aquaculture Ponds and Its Adjacent Sea Area of Qingduizi Bay

于2011—2012年在青堆子湾养殖池塘与临近海域31个站位进行了春、夏、秋、冬4个航次的表层海水采集工作,根据其总悬浮颗粒物(TPM)与有机颗粒悬浮物(POM)的分析数据,结合同步获得的水文环境数据,分析2个区域TPM与POM的平面分布与季节变化。结果表明,养殖池塘TPM浓度全年范围为3.37-44.12 mg/L,平均为15.06 mg/L。邻近海域TPM浓度全年范围为4.06-209.00 mg/L,平均为58.46 mg/L。各季TPM浓度邻近海域均高于养殖池塘。养殖池塘POM浓度全年范围为0.22-7.73 mg/L,平均为1.52 mg/L。临近海域POM浓度全年范围为0.35-16.44 mg/L,平均为4.09 mg/L。养殖池塘与邻近海域POM百分含量存在显著季节变化。

The surface seawater samples of 31 stations were collected for spring,summer,autumn,winter in aquaculture ponds and its adjacent sea area of Qingduizi Bay during 2011 to 2012.Based on the analysis of total particulate matter（TPM） and particulate organic matter（POM）,combining with the data of environmental hydrology,horizontal distribution and seasonal change of TPM and POM in these areas were analyzed.The results showed that the concentrations of TPM in aquaculture ponds varied between 3.37 mg/L and 44.12 mg/L,with the average value of 15.06 mg/L.The concentrations of TPM in adjacent sea area varied between 4.06 mg/L and 209.00 mg/L,with the average value of 58.46 mg/L.In aquaculture ponds,the concentrations of POM varied between 0.22 mg/L and 7.73 mg/L,with the average value of 1.52 mg/L.In the adjacent sea area,the concentrations of POM varied between 0.35 mg/L and 16.44 mg/L,with the average value of 4.09 mg/L.The percentages of POM of aquaculture ponds and its adjacent sea area changed significantly in different seasons.
