摘要:

摘要:采用聚集度指标法、回归模型法和零频率法对九江地区松褐天牛成虫野外的空间格局进行了系统研究。丛生指标I、负二项分布K、K值法CA值均大于0,扩散系数C、扩散指数Iδ、聚快性指标M*/ 大于1,平均拥挤度M*大于 ,L/大于 +1,表明该地区松褐天牛成虫在野外林间呈聚集分布,其聚集类型为聚集度零频率制约型。聚集均数0<λ<2,表明环境因子是造成其空间格局的主要因素。

Abstract:

Abstract: Spatial pattern of Monochamus alternatus Hope adult was investigated by mothods of clump intensity index, regression patterning and zero frequency estimation in Jiujiang. The results measured by clump intensity indexes (I, K, CA>0; C, Iδ, M*/ >1; M*> ; L/> +1 and 0<λ<2 ) suggested the spatial pattern of M. alternatus Hope adult belonged to assemble distribution in pine forest and it was caused by environment factor.
