摘　　要：为研究湘桂走廊褐飞虱的迁飞特点,以期为褐飞虱监测预警及防治工作提供科学依据,利用地处湘桂走廊要冲的3个植保站1990—2014年共25年褐飞虱灯诱数据,挑取灾变性迁飞高峰日,通过HYSPLIT软件模拟其后向轨迹,在个例分析的基础上进行模糊空间聚类分析,分别从个性及共性角度研究湘桂走廊褐飞虱主要迁入路径及虫源地。结果表明:偏南路径(西南、正南、东南)是春、夏季节褐飞虱迁入湘桂走廊的主要路径,占总迁入路径的91%以上,偏北路径少于9%,主要虫源地为越南、老挝北部,其次是海南及广东南部。东北路径是湘桂走廊秋季褐飞虱迁入的主要路径,其中全州站虫源是湖南及江西中南部的占61%,虫源地为湘、赣北部及湖北南部地区的占39%;而永福站秋季迁入虫源中,19%来自广东北部及江西南部,其余的81%来自湖南大部及江西北部、湖北南部。综上所述,湘桂走廊春、夏季虫源主要来自偏南方向的中南半岛及海南稻区,而秋季虫源则主要来自偏北方向的湖南及江西稻区。The objective of this paper is to provide scientific basis for monitoring and preventing and wipingout of the brown planthopper（BPH） pests by studying migration characteristics of brown planthopper in Xiang-Gui corridor. By using the light trapping data of brown planthopper（Nilaparvata lugens St？l） of 25 years（1990—2014） from three plant protection stations located in Xiang-Gui Corridor, the author selected the peakdate of the catastrophic immigratory, then with software HYSPLIT simulation of its backward trajectory, theauthor conducted fuzzy space clustering analysis based on the case analysis, and studied the main immigratorypath and origin of this species in Xiang- Gui Corridor from the aspects of individuality and commonness,respectively. The results indicated that Southward path（southwest, south, southeast） was the main path of thebrown planthopper immigrating into Xiang-Gui Corridor in spring and summer season, representing over 91%of the total number of the immigratory path, while northward path was less than 9%. The origin of the insectwas mainly from the north of Vietnam and Laos, and followed by Hainan Province and south of GuandongProvince. Northeast path was the main path of the brown planthopper immigrating into Xiang-Gui Corridor inautumn. The origin of the insect in Quanzhou station came from Hunan Province and south of Jiangxi Province（accounting for 61%） and north of Jiangxi and south of Hubei Province（accounting for 39%）. Besides, the origin of the insect in Yongfu station came from south of Jiangxi Province and north of Guangdong Province,and the others came from much of Hunan Province, north of Jiangxi and south of Hubei, constituting 19% and81%, respectively. In conclusion, the origin of the insect in Xiang-Gui Corridor mainly came from south of theIndo-China Peninsula and rice producing regions in Hainan Province in summer season, and from north of theHunan Province and rice producing regions in Jiang Province in autumn season.
