| 摘 要： | 根据1998～2005年的东海区上海、宁波、江苏和舟山四大渔业公司的鲐鱼(Pneumatophorus japonicus)生产统计数据以及同期的卫星资料反演的海表温度、叶绿素a浓度数据,利用案例推理方法,设定了上级结果的相似距对下级检索的影响权重因子,进一步研究渔场渔情的分析预报.通过试验性预报实例的预报结果与实际情况比较表明,预测精度达到75%,可以较好地反映出渔场的分布,为渔业资源的开发利用服务.

| Abstract: | In this presentation,considering the comparability weight,the capture data of Scomber japonicu in the East China Sea collected from four major fishery companies during 1998~2005 and sea surface temperature(SST) and chlorophyll a(Chlo-a) derived from satellite images are used to forecast central fishing grounds.The presentation also gives some forecast examples,and the results show the forecast accuracy is up to 75%.This method can offer information for marine fisheries production and fishery managing depart... |
