摘要
本文对1949年以来出现的10次ENSO事件进行了分析,得出如下结果:开始於东太平洋增暖和中大平洋增暖的两类ENSO现象分别对应四川地区粮食产量的减产和增产。此结果对四川地区粮食生产政策的制定及产量的预测研究均有较重要的参考价值。
In this paper,based on the analyses of ten cases of ENSO effects during 1949-1988,it is found that increase and drop in crop production have some correlations with two kinds ENSO effects, i. e. first increasing warming on the east Pacific SST or on the middle Pacific SST. Drop in crop production in Sichuan area is caused by severe drought which is connected with a kind ENSO effect.
