海洋初级生产力的精确估算对渔业资源评估与管理、海洋生态系统和全球变化等研究具有重要意义.传统的现场测量与估算方法必须依赖于随船采样数据.卫星遥感具有能够获取实时的、大尺度的、动态的海洋环境参数的优点,因此卫星遥感日益成为大尺度海洋初级生产力估算的重要手段.本文从海洋水色传感器的发展历程出发,着重归纳了以叶绿素、浮游植物碳和浮游植物吸收系数为参量的海洋初级生产力的遥感估算方法,并就这3类模型的适应性和复杂程度进行了讨论.在此基础上,进一步分析评价了全球海洋初级生产力遥感估算的研究现状.鉴于当前海洋初级生产力遥感估算研究中存在的问题,今后的研究需要在4个方面进一步加强:1)对全球海洋初级生产力估算进行分区域研究;2)加深对浮游植物吸收系数的研究;3)提高海洋遥感技术水平;4)加强实地测量技术的研究.
The accurate estimation of marine primary productivity is of great significance for the research on fishery resources assessment and management, marine ecosystem and global change, etc. The traditional on-site measurement and estimation methods must rely on the data of on-board sampling.Satellite remote sensing has the ability to acquire real-time, large-scale Therefore, satellite remote sensing is increasingly becoming an important means to estimate large-scale ocean primary productivity.This paper starts with the development history of ocean colorimetric sensors and emphasizes that the absorption coefficients of chlorophyll, phytoplankton and phytoplankton are Parameters of the marine primary productivity of the remote sensing estimation methods, and the three types of adaptability and complexity of the model were discussed on this basis, further analysis and evaluation of the global marine primary productivity of remote sensing estimates of the status quo. In view of the current marine primary productivity In the future, the research needs to be further strengthened in four aspects: 1) subregional research on the estimation of global primary productivity of the oceans; 2) deepening the study on the absorption coefficient of phytoplankton; and 3) increasing the level of remote sensing technology of the ocean ; 4) to strengthen the field measurement technology Study.
