摘要:
悬浮颗粒物及粒径是水质重要参数,其分布特征研究有助于加深对海洋生态环境的了解。利用2013年6月和2013年11月LISST-100观测数据,研究了黄、渤海区域悬浮物粒径和浓度的分布情况,浓度分布整体上呈现近岸高远岸低的状况,粒径分布呈现近岸细远岸粗的特征,季节分布特征明显;通过典型断面分析,悬浮物粒径和浓度随着水深变化明显,连续站数据分析结果表明大风对底层颗粒物的再悬浮作用显著,潮流对悬浮物的时空分布有着重要影响;水体衰减系数随着体积浓度变化明显;此外,还研究了悬浮颗粒物粒径Junge分布在黄、渤海区域的适用性。

Abstract:
Suspended particulate matter and particle size is an important parameter of water quality, and its distribution characteristics research helps to deepen understanding of the marine ecological environment. In this paper in June 2013 and November 2013 LISST - 100 observation data, suspended solids in the yellow sea and Bohai sea is studied the distribution of particle size and concentration, concentration distribution on the whole present high coastal shore low status, nearshore particle size distribution, seasonal distributionScharacteristics; By analyzing typical sections, suspended particle size and concentration change with depth, continuous station data analysis results show that the wind to the underlying particle resuspension effect significantly, the trend of time and space distributions of suspended solids have an important impact; Water attenuation coefficient with the change of volume concentration is obvious; In addition, this paper also studied the Junge suspension particle size distribution in the applicability in the yellow sea and Bohai sea.
Key words:  the Yellow Sea and the Bohai Sea  suspended particulate matter  grain size distribution  volume concentration distribution  Lisst-100 instrument
