摘要

摘要: 针对海洋时空要素和相关渔业资源的互动性及非线性关系,分析了带空间结构的变量间关系问题,建立基于海洋要素场时空配置的渔场形成机制发现模型.将海洋要素场的空间配置用邻域进行表达,并将邻域所取得的要素状态变量转换为决策系统的关系表,以提取海洋场时空配置和渔场形成的时空关联规则.以大沙渔场形成的温度场时空配置发现为实例,验证模型的可行性.

Abstract: The relationship between the forming of fishing ground and the oceanic spatio-temporal field is nonlinear.In order to analyse the relationship between them which has the spatio-temporal structures, a spatio-temporal pattern extracting model is provided to find the reason for the forming of fishing ground.In the model, the spatiotemporal structure of the oceanic factors is expressed as neighbour.The elements in the neighbour are filled in the table of decision-making system.After a recursion processing the spatio-temporal rule will be extracted with the spatio-temporal structure.This model is used to find the temperature pattern which is the temperature reason for the forming of the fishing grounds in Dasha area.The practice shows that the model is active and it should be the research front for the marine fishery.
