摘要: 目的:为确定调查长爪沙鼠的抽样数。方法:用Iwao的M*-M公式推导。结果:认定长爪沙鼠种群的分布型为广义负二项分布。提出以种群密度和分布状况为依据,用n=〔(t/D)2*(1/X)〕/S*s*f公式确定抽样规模。应用方差分析、多组均数间两两比较的差异显著性为划分层的依据。结论:分层抽样时面积小于1500ha层的样方数不应少于8个。

Abstract: The formula IWao' M*-M was used to deduce and determine the distribution of Meriones unguiculatus species, which was negative binominal distribution in a broad sense.According to the basis of species density and distributive situation using the formula: n=(t/D)2*(1/X)/S*s*f, no less than eight sampling scopes are needed,if less than 1 500 hectares with statistics analyses.
