摘要:
叶绿素浓度是衡量海洋浮游植物丰度的重要指标,快速准确地测定海水中的叶绿素含量,对于业务化监测和科学研究都具有重要的现实意义。基于活体荧光法的叶绿素传感器操作简便,可长期原位在线监测,能轻易获取大量实测数据,是当前海水叶绿素高精度测量手段的主要发展趋势。由于在海上应用时受到多种环境因素的影响,叶绿素传感器数据与实验室萃取法数值之间存在较大偏差。本文综述了科学界在浊度、光照、温度、盐度等海洋环境因素及藻类生理因素对叶绿素传感器测量的影响规律、影响机理和数据校正方法的研究进展,并对活体荧光法叶绿素传感器海上应用数据质量控制方法的研究思路进行了展望。

Abstract:
Chlorophyll concentration is an important index to measure the abundance of marine phytoplankton. Rapid and accurate determination of chlorophyll content in seawater is of great practical significance for operational monitoring and scientific research. The chlorophyll sensor based on in-vivo fluorescence method is easy to operate, which not only can be in-situ monitored for a long time, but can easily obtain a large number of measured data and becomes the main development trend of high-precision measurement of seawater chlorophyll. However, due to the influence of various environmental factors, there is a large deviation between the chlorophyll sensor data and the laboratory extraction method. In this paper, the research progress of marine environmental factors like turbidity, light, temperature, salinity and algae physiological factors on chlorophyll sensor measurement, along with the influence mechanism and data correction methods are reviewed. The research ideas of in-vivo -fluorescence-based chlorophyll sensor data quality control method are prospected.
