摘要
应用聚集度指标法、回归分析法、零频率方法对泡桐蛛蛾幼虫的空间格局进行测定。结果表明 ,泡桐蛛蛾幼虫在林间呈聚集分布 ,分布的基本成分为个体群 ,零频率方法分析泡桐蛛蛾幼虫种群类型为“聚集度逆零频率制约型”。根据泡桐蛛蛾的空间格局提出了抽样技术 。
The results show that Epiplemidae moza larvae assume the aggregation distribution in forests,the basic component of distribution is individual colony ,E.moza larva community type is analysed as the crowding degree inverse zero frequency restraint type by zero frequency method. The sampling technique is raised according to E.moza spatial pattern,and the theoretical sampling number of investigation in forest and simple sequential sampling analysis table are determined based on the zero frequency method research result.
