POM and DOM were collected in Tieshangang Bay for their spatial distribution and biogeochemical processes in terms of POC, PN, δ13C, and δ15N of POM, DOC, CDOM and FDOM. Together with hydrological and environmental parameters, such as temperature, salinity, apparent dissolved oxygen (AOU), nutrients (NH4+, NO2-, NO3-, PO43-) and chlorophyll-a (Chl <em>a</em>), the sources, biogeochemical behaviors and interactions of OM are discussed in detail.

本研究于铁山湾采集颗粒有机物（Particulate Organic Matter, POM）与溶解有机物（Dissolved Organic Matter, DOM）样品，针对颗粒有机物的颗粒有机碳（Particulate Organic Carbon, POC）、颗粒氮（Particulate Nitrogen, PN）、δ13C与δ15N，以及溶解有机碳（Dissolved Organic Carbon, DOC）、有色溶解有机物（Colored Dissolved Organic Matter, CDOM）与荧光溶解有机物（Fluorescent Dissolved Organic Matter, FDOM），探究二者的空间分布特征与生物地球化学过程。结合温度、盐度、表观溶解氧（Apparent Dissolved Oxygen, AOU）、营养盐（NH4+、NO2-、NO3-、PO43-）与叶绿素a（Chl a）等水文与环境参数，本研究详细探讨了有机物的来源、生物地球化学行为及其相互作用。
