根据1995～1997年在灵芝田对灵芝膜喙扁蝽[Mezira membranacea(Frab)]的调查结果,计算了6种分布型指数,经lwao聚集度指标、Taylor幂法和lwao回归法测定,结果表明,该虫在灵芝田呈聚集分布,其分布强度随种群密度的升高而增强。聚集原因既有环境因子,又有该虫本身的特性。同时建立了该虫的理论抽样公式。 According to the survey of Ganoderma lucidum Mezira membranacea (Frab) from 1995 to 1997, six kinds of distributional indices were calculated, which were determined by lwao aggregation index, Taylor power and lwao regression analysis , The insect was gathered in the Ganoderma lucidum field distribution, the intensity of distribution with population density increased. The reasons for the accumulation of both environmental factors, but also the characteristics of the worm itself. At the same time established the worm’s theoretical sampling formula.
