摘要
应用研究昆虫种群聚集度的若干方法研究鼢鼠鼠害植株的分布型和采用Iwao的方法分析鼢鼠鼠害的最佳抽样数,并对常见的抽样法进行数理统计分析.结果表明,鼢鼠鼠害植株的空间分布为聚集分布,抽样调查方法以平行线式取样法为最佳.
Study on the distribution-model and the sampling investigation technology of zokor pest was carried out in Tailai County,Heilongjiang province in 1992. The result indicated that the distribution-model of pinus sylvestris var. monglica damaged by zokor was intensitive space distribution-model and paralell method was better than other sampling methods.
