摘要：

基于现场实验数据，建立了以悬浮物（SPM）浓度为中间变量、适用于莱州湾海域颗粒有机碳（POC）浓度的反演算法模型，并基于静止轨道海洋彩色成像仪（GOCI-Ⅱ）卫星数据，应用该模型反演结果，首次对2022年“221003”温带风暴潮前后莱州湾及其附近海域POC浓度变化进行了分析。结果表明：该海域POC浓度与SPM浓度之间存在强相关性，相关系数R²=0.87；风暴潮过后，该海域水体表层POC浓度存在“假性”恢复现象；“221003”温带风暴潮对莱州湾及其附近海域POC浓度影响的恢复周期约为15天。

Based on field experimental data, this study established a particulate organic carbon（POC） retrieval algorithm model for Laizhou Bay using suspended particulate matter（SPM） concentration as an intermediate parameter. The model was applied to the GOCI-Ⅱ data to study the POC concentration changes before and after the "221003" extra-tropical storm surge in 2022 in Laizhou Bay and adjacent waters. The results show a strong correlation（R²=0.87） between the POC concentration and SPM concentration in the study area. After the storm surge, a "pseudo-recovery" phenomenon was observed in surface POC concentration. The recovery period for the POC concentration disturbances caused by the "221003" extra-tropical storm surge in Laizhou Bay and its adjacent waters was approximately 15 days.
