摘要
近年来，不少学者提出了各种检验昆虫种群空间分布的模型．本文提出一种新的模型：m~*-v幂模型──m~*＝avb，m~*与v呈幂关系．实例研究验证表明该模型具有适用范围更广和可行性大的优点．同时，根据m~*-v幂模型，推导出与其相配套的序贯抽样方程、最大抽样数量公式和最适抽样单元大小等公式．
In recent years,many scientists have put forward some kinds of patterns to examine insect spatial.A new method to be used to examine insect population spatial pattern is presented by authors in this paper: m*-v power model m*= av^b,the relationship between m*and v is power.Two examples are used to assess the availability of this model,the result shows that its scope of application is wider and feasibility is bigger.In the meantime, according to the m*-v power model,the authors derived a set of new maths formula for sampling insect population,they are: ( 1 ) the boundary equation of sequential sampling; (2) a formula of determining maximum sampling number; (3) a formula for selecting the optimum sample unit size of a sample.
