摘要
本文采用聚集度指标法和回归分析法 ,对杉木云毛虫在林间的空间格局进行测定 ,并采用刀切法给出了其估计区间 ;结果表明 ,杉木云毛虫幼虫在林间为聚集分布 。
Measured by clump intensity index, regressive analysis method and zero frequency method, the spatial pattern of Hoenimnema roesleri Lajonquiere comforted to negative binomial distribution, the later, with colony as it's basis component. Jackknife estimation, the range of clump intensity index was provided. By zero frequency method, Hoenimnema roesleri Lajonquiere population was “zero frequency dependent”. The optimal sampling number of forest survey was analyzed and calculated, and the sequential sampling analysis was presented.
