The Study of Chlorophyll Detection in Coastal Waters Based on Environmental Factors
基于环境因素的沿岸水域叶绿素遥感探测研究

The investigation on ocean chlorophyll always is an emphasis of the study in ocean biological resource and marine ecology. And the remote sensing technology is a powerful tool in chlorophyll detection. Up to now, there has been considerable success in optical remote sensing of chlorophyll in ocase waters. In contrast, chlorophyll retrieval in coastal waters, where the optical properties of inorganic suspended matter and colored dissolved organic matter (CDOM) must also be considered, is still a matter of intense research activity. From the analysis of the living environment of chlorophyll, a new thought that the estimation of chlorophyll concentration using remote sensing based on environment factors, is proposed. The authors chose Pearl River as test area and created a new model of estimation of chlorophyll concentration based on environment factors. Finally, through analyzing the operational precision of the new model, the average relative error of the model based on environment factors is 17.96%, and the common spectral mode is 32.48%. It is proven that joining environment factors in chlorophyll retrieval algorithm can improve the precision of chlorophyll.
