| 摘 要： | 迁飞性害虫褐飞虱对中国和亚洲其它国家和地区的水稻有着十分严重的危害,其迁飞参数的时空变化是种群迁飞这一生态行为的重要体现。应用目前国际上先进的中尺度数值预报模式MM5 (V3.2 )对我国褐飞虱北迁、南返的过程进行了数值模拟,根据模拟结果对害虫的迁出虫源地、迁飞路径、降落区、空中迁飞速率、迁飞高度、迁飞历时和迁飞距离等迁飞参数进行了一系列的数值计算和客观分析,得到了与实际虫情普查和雷达观测资料相当吻合的结果,从而比较精确地阐明了褐飞虱迁出起飞、空中定向飞行、降落迁入等迁飞行为的动力学机制。

| Abstract: | Based on the data of the insect trap catches, the entomological radar surveying, and the weather observations in the China, some processes by which the northward and southward migrations through China of the Brown Planthopper Nilaparvata lugens (BPH) occur during July and October in 1991 were picked out. These processes have been investigated with an advanced mesoscale numerical weather-forecasting model, MM5 (V3.2) and the 3D windborne trajectories of BPH's migration were simulated. Some parameters, such a... |
