| 摘 要： | 在定义种群聚集度指标Ｚ（Ｚ＝Ｖ／ｍ－１＋Ｖ）的基础上，本文提出一个种群空间格局研究的新模型：Ｚ—Ｖ模型（Ｚ＝Ａ＋ＢＶ），参数Ａ，Ｂ的９种不同组合型式分别揭示出不同的空间格局信息。经实例验证和比较表明，Ｚ—Ｖ模型具有更广泛的适用性和较高的可靠性，能客观地反映出种群空间格局的本质特征。基于Ｚ—Ｖ模型，文中还推导出了简单随机抽样确定理论抽样数和最适样方大小的公式以及序贯抽样决策模型

| Abstract: | Based on population group socialbility index Z(Z=V/m-1 V) a new model Z-V(Z=A BV) for research of spatial patterns of population has been established,in which information on spatial patterns was given though 9 kinds of combinations between parameter A and B. It is proved that the model was reliable and usable and could reveal essential characteristics of spatial patterns of population. Moreover,simple random sampling numbler, an equation for minimum sample decision and a model of sequential sampling decision have been developed according to the model Z-V. |
