渤海海域叶绿素浓度的遥感反演研究

Study on Retrieval of Chlorophyll Concentration by Remote Sensing in Bohai Sea

以渤海海域为研究区域,以MODIS1B卫星影像为数据源,利用MODIS 250.m分辨率的波段反射率构建的NDPI(Normalized Difference Pigment Index)遥感指数结合叶绿素质量浓度(ρ)实测值进行回归拟合分析,建立基于MODIS1B数据的渤海海域叶绿素质量浓度遥感提取模型,并应用该模型反演出渤海海域叶绿素浓度的分布情况,对其分布进行了分析和评价.研究结果表明,利用MODIS1B数据监测渤海海域的水质情况是可行的.

On the basis of MODIS1B remote sensing data in Bohai Sea,using the 250 m resolution wave I and 2 reflectivity to make the NDPI （Normalized Difference Pigment Index）remote sensing index combination compare with chlorophyll mass concentration （p） measurements by correlation analysis. The chlorophyll mass concentration extraction model of remote sensing in the Bohai Sea was established on the basis of MODIS1B data. The distribution of chlorophyll mass concentration of Bohai Sea was analyzed by the model. The result shows that MODIS1B image data is preferably useful in quantitative retrieval model of chlorophyll mass concentration in Bohai Sea.
