桉木虱种群突变模型的研究

Study on the Mutation Model of the Jumping Phant,Controledby the Tempereture and Rainfall

桉木虱受温度影响下的种群动态突变模型为抛物线形。受温度和雨量综合因子作用下的种群动态为椭圆形。温度、雨量是影响桉木虱种群突变的主导因子：使用突变强度（ｉ为控制变量ｎ＝１，２，３，…）对临界线和区域进行确定。

The mutation model of the Jumping phant's quantity development included parabola form and ellipse form. The parabola form mutation model was controled by tempereture. The ellipse form mutation model was controled by tempereture and rainfall. The tempereture and rainfall were the cardinal control factors, The mutation intensity were used to define the boundary of mutation and mutation region.
