摘要

摘要: 为了寻求一种简单、快速、连续测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。前期实验结果已经证明悬浮泥沙含量与电导率之间有很好的线性关系。在此基础上扩大研究范围,并对影响悬浮泥沙含量与电导率关系的因素进行定量分析,结果表明,盐度、温度、颗粒粒径对电导率具有一定的影响,其中盐度的影响最大,颗粒粒径的影响最小,几乎可以忽略。在此基础上通过大量的实验数据初步建立起在盐度、温度较大变化范围内电导率与泥沙含量的一般函数关系,为实现海水悬浮泥沙含量的现场电导率原位监测系统提供可靠的数据支持。

Abstract: In order to find a simple and continuous method to measure a suspended sediment content in a high turbidity region, a conductivity sensor was used to examine the conductivity in different sediment content seawater. Sediments from the Huanghe River Delta were used. The previous test has proven that good linear relationships exist between the suspended sediment content and the conductivity. On that basis, the scope of study was expanded. And the influencing factors of such relationships were also investigated. The results show that salinity, temperature and particle size have some influence on the conductivity, among which salinity is the most influencing factor and the influence of particle size is not important. In this way, the general relationship between the suspended sediment content and electrical conductivity was achieved through a large number of test data in a large scale of salinity and temperature. They provide reliable data support for realizing the monitoring system in situ.
