| 摘 要： | 褐飞虱是我国主要的水稻害虫，有着复杂的空间结构，地统计学可用来分析空间相关变量的结构和插植模拟空间相关变量的分布，运用地统计学中的变差函数和克立格插值法对广东省褐飞虱种群3个主要世代在早稻田间的空间结构进行分析和模拟的结果表明，大尺度的褐飞虱田间种群的空间分布为聚集型，不同世代群在田间的具体分布情况，广东西部地区第一世代褐飞虱的发生密度均高于东部地区。

| Abstract: | Brown planthopper(BPH),Nilaparvata lugens,is a major pest of rice.Its spatial distribution of different generations in Guangdong Province was studied by using variograms.The results showed that this population distributed in a clump pattern in rice fields during the 1st rice season.3 generations of this population had different spatial structures,with the clump range of 400km,200km and 205km respectively in the 1st rice season.The simulation distribution maps of BPH,which was interpolated by Ordinary Kriging,showed that the density of BPH populations in west Guangdong province were higher than that in the east.The effect of sampling size on the spatial structure of BPH was not significant. |
