中文摘要：叶绿素a质量浓度是水体水环境一个重要指标。本文结合实测的叶绿素a质量浓度、水体的光谱数据和FY-3A中等分辨率成像光谱仪的数据,研究利用FY-3A遥感监测湛江湾及其邻近海域叶绿素a质量浓度的可行性。研究结果表明,湛江湾海域大部水体接近一类水体,二类水体主要集中在湛江港附近的狭小封闭海域;OC4算法可以用于湛江湾海域的叶绿素a质量浓度的遥感监测,实测叶绿素a质量浓度与反演的叶绿素a质量浓度具有较好的相关性,相关系数R达到0.7以上;FY-3A中等分辨率成像光谱仪的数据可以较好地反映湛江湾海域叶绿素a质量浓度的空间分布。

外文摘要：The chlorophyll-a concentration is one of important index for the water environment. Based on the measured chlorophyll-a concentration, water spectral data and FY-3A moderate resolution imaging spectrometer data, the feasibility of using FY-3A to monitor the chlorophyll-a concentration in Zhanjiang Bay and its adjacent waters was researched. The results show that the waters of the Zhanjiang Bay is close to case one water, and case two water is mainly distributed in the narrow and enclosed area near the Zhanjiang Harbour; and the OC4 algorithm can be used to monitor the remote sensing of the chlorophyll-a concentration in the Zhanjiang Bay. The measured chlorophyll-a concentration has good correlation with the retrieved one, and the correlation coefficient R is better than 0.7. FY-3A medium resolution imaging spectrometer data can reflect the distribution of chlorophyll-a concentration in Zhanjiang Bay.
