摘要
在南极磷虾环境因素监测中,遥感技术的不断发展适应了实时监测和大范围观测的要求,利用遥感技术对环境因素的监测是研究南极磷虾(Euphausia superba)资源分布的关键,是研究南极磷虾渔场时空变化及渔情、渔汛预报的基础,遥感技术的应用有利于准确评估资源量,使磷虾得到合理利用和可持续开发。本文综述了国内外学者利用遥感技术,在叶绿素、海表温度(SST)、盐度、海冰消长与迁徙等南极磷虾环境因素方面进行的研究。利用遥感技术发现,南极海域叶绿素浓度与海冰覆盖相关,遥感监测海冰的变化对初级生产力有着重要作用。另外,有学者对南极海域遥感反演算法做出了研究,有助于获得南极海域高精度环境数据。针对遥感技术在物理海洋中的应用研究,我们可以从海流、温度梯度等动力因素进行分析,为今后南极磷虾迁徙规律、资源分布和养护提供理论基础。
In the monitoring of Antarctic krill environmental factors,the continuous development of remote sensing technology has adapted to the requirements of real-time monitoring and large scale observation.Using remote sensing technology to monitor the environmental factors is the key to study the distribution of Antarctic krill resources.And it is the basis of the research on temporal and spatial variation of Antarctic krill fishery and fishery and fishing season forecast.The application of remote sensing technology to accurately assess the amount of Antarctic krillresources, make reasonable use and sustainable development.This paper summarized the domestic and foreign scholars research chlorophyll,sea surface temperature(SST),salinity, sea ice dynamics and migration and other environmental factors by using remote sensing technology.Using remote sensing technology, it is found that the chlorophyll concentration is related to the sea ice cover, and the change of sea ice has an important effect on primary productivity.In addition, some scholars have made a research on the Antarctic sea remote sensing retrieval algorithm, which is helpful to obtain the high precision environmental data.
