摘要
渔场的形成机制和分布规律受到鱼类自身生物特性和外界环境条件的影响,海洋遥感能够获取的大范围同步的海洋热力、海洋水色和海洋动力地形等海洋环境要素,为人类理解海洋鱼类种群动力机制提供了丰富的信息。运用渔场分析和预报模型,结合地理信息系统技术对多元数据的集成为渔业的即时管理提供了发展方向。目前运用海洋遥感进行渔场研究存在的问题有:1.海洋遥感手段仅能获得渔场表层的信息,必须结合浮标海洋剖面信息才能更好地解释鱼类栖息环境;2.运用海洋遥感技术获取渔场水色信息的精度不高,给渔场资源的研究带来了困难;3.利用遥感技术进行渔场的实时预报容易受到天气条件的影响;4.如何建立科学的渔场预报模型的评价体系是渔场预报亟待解决的问题;5.渔场分析和预报走向智能化、自动化的关键技术还有待深入研究。遥感技术不断向高光谱和定量方向发展,为渔场资源的定量评估提供重要条件。在高效开发和利用海洋生物资源的同时,对海洋生物的资源存量进行定量的评估从而指导人类合理开发和可持续利用大洋渔业资源具有重要的意义。
The use of fishing ground analysis and forecasting model combined with geographic information system technology integrating multi-channel data feeds development of fishery real-time management.At present,there are several problems on application of ocean remote sensing on fishing ground analysis： firstly,ocean remote sensing which can only obtain surface information of fishing ground combined with oceanic vertical data from drogue can explain fish habitat conditions in detail;secondly,fishing ground color element from ocean remote sensing is not accurate enough to support fishing ground resources research;thirdly,fishing ground real-time fore-cast by remote sensing technology is easily influenced by weather conditions;fourthly,how to build scientific evaluation system of fishing ground model needs to be settled;finally,the key technology of intelligentized and automated fishing ground analysis and forecast needs further research.Remote sensing technology to the devel-opment of high spectral and quantitative direction,provide important conditions for the quantitative assessment of the fisheries resource.Quantitative assessment of the resource inventory of marine life in efficient development and use of marine biological resources,to guide mankind to rational development and sustainable use of ocean fishery resources is of great significance.
