The red tide in the East China Sea is a typical coastal phenomenon resulting from the proliferation and accumulation of harmful algal blooms. Organic matter is one of the most important components of sediments in red tide areas. It is closely related to the growth and reproduction of phytoplankton and can affect water quality and ecosystem health. Therefore, it is necessary to investigate the source and distribution of organic matter in sediments of red tide areas and explore its relationship with phytoplankton community.Research objectives:1. To determine the sources of organic matter in sediments of red tide areas in the East China Sea through stable carbon isotope analysis;2. To analyze the composition and abundance of phytoplankton in the water column and sediments of red tide areas;3. To explore the relationship between organic matter and phytoplankton community in red tide areas.Research methods:1. Collection of sediment and water samples from red tide areas in the East China Sea;2. Analysis of stable carbon isotope composition of organic matter in sediments to identify sources;3. Analysis of phytoplankton composition and abundance in sediments and water using microscopy and HPLC;4. Statistical analysis to explore the relationship between organic matter and phytoplankton community.精品文档---下载后可任意编辑Expected results:1. Identification of sources of organic matter in red tide sediments;2. Analysis of phytoplankton composition and abundance in red tide sediments and water;3. Correlation analysis between organic matter and phytoplankton community, which might provide insights into the mechanisms of red tide occurrence.Significance:The research can provide scientific support for the prevention and control of red tide in the East China Sea. Understanding the relationship between organic matter and phytoplankton community is essential for predicting and managing red tide outbreaks.
