摘要
应用特征根回归法建立了拟水狼蛛 (Piratasubpiraticus)、食虫瘤胸蛛 (Oedothoraxinsecticeps)、粽管巢蛛 (Clubionajaponicola)和菱头跳蛛 (Bianorhotingchiehi) 4种蜘蛛与褐飞虱 (Nilaparvatalugens)共存系统捕食量的特征根回归模型 :y =6 .6 6 0 0 +6 .3399(- 0 .0 138X1 +0 .0 895X2 +0 .0 0 78X3 - 0 .10 6 7X4 +0 .6 74 2X5 ) .以此模型对蜘蛛捕食量进行了模拟或预测分析 ,并同LS回归方法进行了比较 .结果表明 ,特征根回归法可用于蜘蛛对褐飞虱捕食量的定量分析 ,比LS回归方法提高精度 10 % .
A latent root regression model was constructed for analyzing the predation quantity in a coexistence system of four spiders ( Pirata subpiraticus,Oedothorax insecticeps,Clubiona japonicola, and Bianor hotingchiehi ) with brown planthopper ( Nilaparvata lugens ). The predation quantity of the spiders in a multi species coexistence system could be predicted by y= 6.6600 +6.3399(-0.0138X 1 * +0.0895X 2 *+0.0078 X 3 * -0.1067X 4 * +0.6742X 5 * ). The result showed that compared to LS regression, the accuracy of predation quantity predicted by the model increased by 10%.
