例谈不同因素对标记重捕法估算值的影响与计算

Illustration on the impact of different factors on the estimation value of the mark-recapture method and calculation

标记重捕法实施有许多前提条件。本文先以不同重捕方式对种群数量影响进行定性分析,再应用模型法定量计算不同因素对标记重捕法估算值的影响,尝试阐明定性计算法、定量计算法在分析种群数量时的各自特点,以及在特定情况下使用定量法计算种群数量的优点。

There are many prerequisites for the implementation of the mark-recapture method.This article first qualitatively analyzes the impact of different recapture methods on population estimates,and then applies a model-based quantitative calculation to assess the impact of different factors on the estimation value of the mark-recapture method.It attempts to clarify the characteristics of qualitative and quantitative calculation methods in analyzing population estimates,as well as the advantages of using the quantitative method to calculate population estimates in specific situations.
