利用2000 - 2018年的中分辨率成像光谱仪（MODIS）表面反射率数据，分析了胶州湾海水透明度（Zsd）的时空分布特征。并对胶州湾2000-2018年的Zsd产品进行了反演。对Zsd结果的分析表明，胶州湾相对Zsd的空间分布特征较为稳定，呈现东南高西北低的特点。胶州湾的年平均Zs呈明显的上升趋势，年平均增加约0.02m。水深和风速分别是影响胶州湾浮游生物空间分布和年际变化的重要因子。
The Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance data were used to analyze the temporal and spatial distribution characteristics of water clarity (Zsd) in the Jiaozhou Bay, Qingdao, China, in the Yellow Sea from 2000 to 2018.Zsdretrieval models were regionally optimized using in-situ data with coincident MODIS images, and then were used to retrieve theZsdproducts in Jiaozhou Bay from 2000–2018. The analysis of theZsdresults suggests that the spatial distribution of relativeZsdspatial characteristics in Jiaozhou Bay was stable, being higherZsdin the southeast and a lowerZsdin the northwest. The annual meanZsdin Jiaozhou Bay showed a significant upward trend, with an annual increase of approximately 0.02 m. Water depth and wind speed were important factors affecting the spatial distribution and annual variation ofZsdin Jiaozhou Bay, respectively.
