通过对1986-2003年新疆草原蝗虫发生面积与大气环流指数74项特征值的相关分析,筛选出与新疆蝗虫发生有显著关系的大气环流指数因子,采用逐步回归方法建立4个新疆蝗虫发生面积预测预报模型,并对模型进行了检验.利用模型对2004-2006年新疆蝗虫发生面积进行延伸预测,并与实际蝗虫发生面积进行比对,最终挑选出预报准确率在85%以上、对新疆草原蝗虫发生面积趋势具有一定预报能力和应用价值的模型,并初步分析了大气环流特征量与蝗虫发生面积的关系.
通過對1986-2003年新疆草原蝗蟲髮生麵積與大氣環流指數74項特徵值的相關分析,篩選齣與新疆蝗蟲髮生有顯著關繫的大氣環流指數因子,採用逐步迴歸方法建立4箇新疆蝗蟲髮生麵積預測預報模型,併對模型進行瞭檢驗.利用模型對2004-2006年新疆蝗蟲髮生麵積進行延伸預測,併與實際蝗蟲髮生麵積進行比對,最終挑選齣預報準確率在85%以上、對新疆草原蝗蟲髮生麵積趨勢具有一定預報能力和應用價值的模型,併初步分析瞭大氣環流特徵量與蝗蟲髮生麵積的關繫.

By analyzing the correlation between the area of grasshopper occurrence and 74 characteristic indexes of atmospheric circulation in Xinjiang from 1986 to 2003, the factors of atmospheric circulation which were significant related with grasshopper occurrence were selected. And then, 4 models for predicting the area of grasshopper occurrence were established by using the successive regression and tested. The area of grasshopper occurrence in Xinjiang from 2004 to 2006 were predicted with these models, then the predicted and actual results were compared and a model, its accuracy rate for prediction was more than 85%, was selected. Meanwhile, the relationship between the factors of atmospheric circulation and the area of grasshopper occurrence were analyzed.
