摘要

摘要: 基于2014年5月和8月珠江口海域的现场和实验测量数据，分析了光学因子和生态参数的动态变化特征，并找出该海域的主导光学因子；基于模拟的MODIS数据，构建了水体组分特征波长处吸收系数的遥感反演模型，并结合MODIS卫星遥感影像，依据IOCCG规则对主导光学因子进行遥感分类，揭示了珠江口海域2014年逐月水体主导光学因子的动态变化特征。结果表明，珠江口海域水体以a_d、a_g以及两种共同主导类型为主，并且a_g、a_d两种光学因子主导类型所占比例最大，其次是a_g主导类型，a_d主导类型所占比例最小。同时发现a_d（442）、a_dg（442）均与无机悬浮物浓度有较好的正相关关系，说明CDOM和悬浮泥沙具有相似的来源和动力变化过程。

Abstract: Based on the field and laboratory bio-optical datasets from the May and August cruises in the Pearl River Estuary in 2014, the variability of bio-optical parameters was analyzed to examine the dominant optically active components in a highly turbid water. Using the simulated and field MODIS data, the retrieval algorithms for estimation of the absorption coefficients at a specific wavelength of water components were developed and classified following the IOCCG reports, to assess the spatial and temporal variability of dominant optically active components in the Pearl River Estuary. The results demonstrated that a_d, a_g or both of them (a_dg) dominated the optical properties of water in this estuary, with a_dg accounting for an average of 76.9% in 2011, followed by a_g and a_d. Furthermore, a_d(442) and a_dg(442) were both well positively correlated with c_ISS, which were shown to provide comparable information on CDOM and detritus present.
