| 摘 要： | 为明确白背飞虱Sogatella furcifera(Horváth)迁入种群的中小尺度虫源地和降落机制,提高白背飞虱异地预测的精确度,2012年在广西兴安县应用探照灯诱虫器对白背飞虱进行了分时段监测;选取2012年6月4日至6月10日广西稻区的一次白背飞虱北迁过程作为典型个例,并运用中尺度气象预报WRF模式和FLEXPART模式进行大气背景分析和白背飞虱迁飞轨迹模拟。结果表明:低空急流为此次迁飞过程提供运载气流,下沉气流、降雨、气温屏障使白背飞虱聚集降落;此次迁入白背飞虱虫源地主要包括越南北部的木州、原平和平卢,以及广西的博白县和上思县。表明通过WRF-FLEXPART模拟平台进行白背飞虱迁飞路径的研究是可行的。

| Abstract: | In order to elucidate the source areas and landing mechanisms of immigrant planthoppers in a mesoscale region and improve the accuracy of offsite forecast,a time-dividing monitoring of the white-backed planthoppers (WBPH,Sogatella furcifera(Horváth)) during different periods was conducted with the searchlight trap in Xing''an County,Guangxi Zhuang Autonomous Region in 2012.In this study,weather datasets on peak days of light-trap catches of immigrant WBPHs in Guangxi Zhuang Autonomous Region during June 4-10,2012,were selected to conduct the atmospheric background fields analysis and trajectory analysis with the weather research and forecast (WRF) model and the flexible particle dispersion (FLEXPART) model.The results showed that the low-level jet offered carrying airflow for this process,downward flows,rainfall and temperature barrier promoted WBPH to gather and land.The source areas were Moc Chau,Nguyen Binh,Binh Lu,in northern Vietnam,and Shangsi County,Bobai County in Guangxi Zhuang Autonomous Region.These results indicated that WRF-FLEXPART was an effective method for simulating the migration path of white-backed planthoppers. |
