摘要: 根据2003—2009年重庆市秀山县白背飞虱迁入前期的田间调查资料,应用地理信息系统(GIS)结合传统空间分布分析方法,研究了该县白背飞虱空间分布格局及其动态。结果表明:2003—2009年的白背飞虱种群在全县范围呈现明显的聚集分布格局;反向距离插值图显示,不同年度聚集中心和聚集程度是变化的。总的分布格局是,秀山县中部平坝地区的官桥、官庄、平凯镇发生较重,7年的调查数据中有4年的聚集中心位于此;而周边三沟两岔地区发生相对较轻,只有2007年聚集中心位于南部,2008年的聚集中心位于东部,2009年聚集中心位于北部和西部。

Abstract: Based on the 2003-2009 field survey data of white-backed planthopper Sogatella furcifera at its early immigration stage in Xiushan County of Chongqing, and by using geographical information system (GIS) and traditional spatial analysis methods, this paper studied the spatial distribution pattern and its dynamics of the planthopper in the county. In 2003-2009, the S. furcifera population within the county presented an obvious aggregated spatial distribution, and the inverse distance weighted interpolation figures showed that the aggregation center and distribution pattern differed in different years. Overall, S. furcifera population more aggregated in the middle area of the county, including Guanqiao, Guanzhuang, and Pingkai towns, with the aggregation center there in four of the seven years, but less aggregated in surrounding mountain areas, only with the aggregation center in the south of the county in 2007, in the east of the county in 2008, and in the north and west of the county in 2009.
