| 摘 要： | 以2003年MODIS数据为数据源，在图像处理、空间插值的基础上作海温与叶绿素浓度的空间相关分析。结果表明，整个海域的叶绿素浓度和海温的分布具有明显的区域和季节变化特征。基本规律是叶绿素浓度从近岸向渤海中央递减；温度则随季节发生变化，随着温度升高，近海叶绿素浓度增高，而渤海中央区域叶绿素浓度降低。渤海叶绿素浓度的分布与河口径流、季节等因素有关。从空间关系看，海温与叶绿素浓度不存在很明显的空间分布相关性，但不同季节有不同的相关性。上述研究可用于估算海洋初级生产力。

| Abstract: | In this paper,based on MODIS data,the image processing and spatial interpolation techniaues are used to make the spatial correlation analysis of SST and chlorophyll concentration.It is shown from the analysis results that the SST and chlorophyll concentration distributions in the Bohai Sea have obvious regional and seasonal variation characteristics.The basic variabilities are as follows,the chlorophyll concentration decreases from the inshore area to the central Bohai Sea;the sea surface temperature(SST) has seasonal variations,the chlorophyll concentration in the inshore area increases with increasing SST,and that in the central Bohai Sea decreases with increasing SST.The chlorophyll concentration distributions in the Bohai Sea are related to the river mouth runoff and season.The spatial correlation between SST and chlorophyll concentration is not significant,but the correlations between the two in different seasons are different.The above-mentioned studies can be used for estimating the marine primary prodution. |
