摘要: 对1952—2001年中国大豆食心虫发生面积与食心虫发生前一年1月至当年4月中74个环流特征量及286个网格点海温逐月及不同组合时段距平值进行相关分析,筛选出了大气环流和海温因子,通过逐步回归,分别建立了中国大豆食心虫发生面积的大气环流和海温预报模型,并对模型进行了拟合和延伸预报。结果表明:模型的拟合和延伸预报效果均较好,2002—2004年大气环流模型延伸预报平均准确率达88%,海温模型延伸预报准确率达86%。

Abstract: This paper analyzed the relationships between occurrence area attacked by soybean pod borers in China during 1952-2001 and 74 atmospheric circulation parameters from previous January to current April, and monthly and average different period combination of ocean temperature from 286 gridding points. The atmospheric circulation and ocean temperature factors were screened out. Through step regression, the occurrence area forecast models concerning atmospheric circulation and ocean temperature were established and verified separately. The results showed that the occurrence area attacked by soybean pod borers could be preferably simulated and predicted by these models. The forecast accuracy reached 88% by the atmospheric circulation model and 86% by the ocean temperature model through extending prediction for2002-2004.
