SATELLITE REMOTE SENSING FOR OCEANIC PRIMARY PRODUCTIVITY

从海水的光学特性入手,依据卫星探测海洋初级生产力的基本原理,详细讨论了大气校正过程,并较为全面地阐述了现有的一些海洋初级生产力模式。通过列举个例对这些模式进行分类讨论,并对模式应用中的一些问题作出了分析和讨论,在此基础上指出了其存在的问题和发展的方向。

Based on the introduction of optical properties and the classification for ocean water, the fundamental principles of satellite measuring oceanic primary productivity （OPP） were illuminated and the processes of atmospheric correction were discussed in detail in this paper; in addition, some extant oceanic primary productivity models were reviewed completely. At present, many scientists are engaged in the research on satellite remote sensing for OPP, and most OPP models are based on chlorophyll. Firstly, these models are discussed by classifying via given some specific examples. These productivity models are often delineated into empirical, semi-analytical, and analytical models ; they can also be classified into wavelength-resolved models （ WRMs ） , wavelength-integrated models （WIMs） , time-integrated models （TIMs） and depth-integrated models （DIMs） based upon the implicit levels of integration. Meanwhile, some problems relevant to the application of these models have also been discussed.
