摘  要:
2010年7月在会泽县金钟镇青云村云南松林中进行楚雄腮扁叶蜂虫口密度的随机抽样调查,利用DPS数据处理系统对该虫进行空间分布型研究.各项聚集度指标值、回归方程参数组合以及空间分布型频次分布检验结果表明,该虫的空间分布型为聚集型的负二项分布.最适抽样数研究结果表明,同一误差水平下,随种群密度的增加,抽样数相应减少.

摘  要:
Using DPS data processing system,the spatial distribution pattern of Cephalica Chuxiongnica larvae was analyzed from random larvae population density survey on Pinus Yunnanensis forest at Jinzhong town,Huize County in July 2010.The frequency distribution test of the aggregation index values,the regression equation parameters and the spatial distribution pattern showed that the spatial distribution pattern of the insect were negative binomial model of aggregation.And results of optimal sampling number showed that under the same error level,with the population density increases,the sampling number correspondingly reduced.
