摘要
对1956～1984年主要气候因子季风、台风、海表温度、径流和东中国海主要经济鱼种渔获量残差、渔获量比例进行了相关性分析。结果表明:季风、台风、海表温度对中上层鱼类起负面影响,而季风、台风、海表温度、径流4个气候因子对中下层鱼类起到积极作用,相关系数的P值均小于0.05。中上层鱼类受到气候变化的直接影响,而中下层鱼类则受到间接影响,滞后时间范围为:0～5年,并具有多年连续性。
The correlation between major climatic factors（monsoon,typhoon,SST and runoff） and the catch residual and the catch ratio of major commercial fishes in the East China Sea from 1956 to 1984 was analyzed.The results showed that monsoon,typhoon and SST have negative influence on pelagic fishes,but monsoon,typhoon,SST and runoff have positive impact on demersal fishes,and all the P-values of the correlation coefficient are below 0.05.Therefore,the pelagic and demersal fishes encounter a direct and indirect impact from the climate changes,respectively,and the range of the time lags,which have continuity for several years,is from 0 to 5 year.
