摘要
采用扩散系数C,聚集度指标I,Cassie指标C_A,Morisita扩散指标I_δ,Lloyd聚块性指标L,Iwao的m-m回归分析法和Taylor的幂指数法等7种方法测定了金钱松小卷蛾幼虫的空间分布型,并探讨了其在最适抽样数、资料代换及序贯抽样中的应用。
This paper analyzes the data from Mount Mogan by means of 7 kinds of methods. All indices show that the larvae are of aggregation patterns. This paper discusses briefly the application of the results in data transformation, determination of the best sampling numbers and sequential analysis, too.
