中文摘要：2014年对湛江湾表层海水悬浮物含量的2个季节调查结果显示,湛江湾表层海水悬浮物含量冬季显著高于夏季,区域分布不显著。其中,冬季悬浮物含量变化范围为2.1~28.2 mg/l,平均值为11.1 mg/l;广泛夏季悬浮物含量变化范围为1.6~18.0 mg/l,平均值为6.7 mg/l。悬浮物烧失量显示,无机质是湛江湾表层水体悬浮物主要成分。通过对悬浮物含量、悬浮物中值粒径、悬浮物烧失量及主要环境相关因子做pearSon相关性分析,结果显示,悬浮物含量与悬浮物粒径呈显著性负相关,相关系数为-0.418(p<0.05),与水温呈极显著性负相关,相关系数为-0.572(p<0.01);与ph、叶绿素a、do呈极显著性正相关,相关系数分别为0.677、0.548、0.553(p<0.01)。其他因子相关性不明显。

外文摘要：According to the two seasonal investigated data of suspended solids(SS)content on surface waters in Zhanjiang bay in 2014.The content of suspended solids in winter of Zhangjiang Bay is higher than summer obviously,the distribution of district faintly.The content of suspended solids ranges from 2.1 mg/L to 28.2 mg/L in winter with an average of 11.1 mg/L,while the content of suspended solids varied from 1.6 mg/L to 18.0 mg/L in summer with an average of 6.7 mg/L.Person correlation analysis of the Suspended solids(median particle size SS and Loss-on-Ignition in SS)and main environmental factors,the result show:the content of suspended solids was negative relative to the median particle size SS with the coefficient correlation of-0.418(p<0.05),and was significant negative relative to the temperature with the coefficient correlation of-0.572(p<0.01).Meanwhile,The Person correlation analysis had led to a conclusion that the content of suspended solids was significant positive relative to pH as well as chlorophyll a and dissolved oxygen,the coefficient correlation was 0.667(p<0.01)(to chlorophyll a with the coefficient correlation of 0.548(p<0.01)and to dissolved oxygen with the coefficient correlation of0.553(p<0.01),No obvious correlation was found with other factors.
