摘    要:为了寻求一种简单、快速、连续确定悬浮泥沙含量的方法,以高含沙量海区黄河口泥沙为研究对象,利用电导率仪测定了不同悬浮泥沙含量水体的电导率,建立起了悬浮泥沙含量与电导率之间的关系,并对影响上述关系的因素进行了分析,结果表明,悬浮泥沙含量与电导率之间有很好的线性关系;盐度、颗粒粒径对电导率具有一定的影响,其中盐度的影响最大,颗粒粒径的影响较小。在盐度变化范围有限的高悬沙含量海区,用电导率的方法来实现现场监测悬浮泥沙含量是可行的。

关 键 词:电导率    悬浮泥沙    含量测定    影响因素

Abstract:In order to find a simple,continuous method to measure suspended sediment content in a high turbidity region,experiments were conducted to examine relationship between suspended sediment contentand electrical conductivity.Sediments from the Huanghe River Delta and a conductivity sensor were used. The influencing factors of influencing this relationship were also investigated.The results show that good linear relationships exist between suspended sediment contentand electrical conductivity;salinity and grain-size have some influence on the electrical conductivity,of which salinity is the most influencing facto rand grain-size has little influence.The linear relationships suggest that it is feasible to measure suspended sediment content in situ using the electrical conductivity sensor.
Keywords:conductivity  suspended sediment  content measurements  influencing factors
