捕获网法及其参数估计

介绍了一种采用标记-重捕获技术估计动物种群密度的捕获网抽样方法。在回顾该方法国内外研究进展的基础上,分析了由于该法参数估算过程复杂和缺乏相关的处理计算软件对其应用的限制,提出了捕获网抽样方法参数估计的表格化处理技术。并以美国New Mexico附近白脚鼠的种群密度调查数据分析为例,介绍了嵌入DPS电子工作表的捕获网抽样参数估计表格化处理过程;最后就捕获网抽样参数估计的研究重点提出一些看法和展望。

Trapping web model and its parameter estimation

This paper introduced the trapping web model of mark-recapture sampling for estimating the density of animal population,and reviewed its research advances Because this model is quite complicated in estimating parameters and no statistic soft is available in China,its application was limited.The authors put forward a method of spread sheeting to estimate the model parameters and embed them in the worksheet of DPS software.An example Peromyscus spp.population density near New Mexico,USA was conducted,and the future research directions of trapping web model were dincussed.
