摘要
利用实测光谱数据及水体叶绿素浓度数据建立了基于MODIS数据的叶绿素反演模型,并利用MODIS L1B数据对研究区的叶绿素浓度进行了反演。通过分析烟台近海水体叶绿素浓度分布得出,烟台近海水体叶绿素浓度由沿岸向海延伸,叶绿素的浓度逐渐增加;通过不同月份的叶绿素浓度分布状况发现,夏季水体叶绿素浓度含量最高,冬季最低。
The retrieval model of chlorophyll-a is built according to the in situ spectral data and chlorophyll-a concentration.Moreover,the MODIS L1 B data is applied to map the chlorophyll-a distribution of Yantai coastal waters. The distribution map of chlorophyll-a is analyzed according to monthly chlorophyll-a concentration distribution. From the chlorophyll-a distribution map,we could conclude that the chlorophyll-a concentration of near-land waters is higher than that of external waters,the nearer to the land,the higher chlorophyll-a concentration. Moreover,the chlorophyll-a concentration in summer is the highest among all the seasons in 2009 and the lowest chlorophyll-a in waters is in winter.
