占域模型的原理及在野生动物红外相机研究中的应用案例

Using occupancy models in wildlife camera-trapping monitoring and the study case

占域模型解决了探测率常常被忽略的问题,所需数据要求简单,具有数据来源广泛、经济高效等优点,越来越多地应用在野生动物监测和研究中。本文综述了占域模型的概念、基本原理及其近年来在国内外的应用进展,并以红外相机数据为基础,总结了占域模型所要求的数据采集、处理和分析等流程和基本原则,同时以广东车八岭国家级自然保护区的花面狸(Paguma larvata)作为研究案例,展示了占域模型的数据分析过程。最后根据近年来的发展和应用,总结了占域模型的应用范围和发展趋势以及研究中存在的主要问题。

Occupancy models have the advantage of accounting for imperfect detection, they have simple and flexible data requirements as we all high economic efficiency. For these reasons, occupancy models have been increasingly applied in wildlife research. In this paper, we introduced the basic principles and use of the occupancy models. Using camera trap data we outlined the operational procedures and considerations from field investigation to data analysis. Using the masked palm civet(Paguma larvata) in the Guangdong Chebaling National Nature Reserve as an example we demonstrate the basic steps of how estimate occupancy and detect probability. Finally, according to occupancy model research from recent years, we summarize use trends and main limitations in the research.
