摘要:

黑冠鹃隼(Aviceda leuphotes)是我国国家二级重点保护野生动物, 也是多地观鸟产业的明星物种。然而, 目前关于黑冠鹃隼的生态学研究非常稀缺, 极大限制了我们对该物种采取针对性的保护措施。有鉴于此, 本研究结合福建省明溪县林业局前期鸟类记录, 于当地选择了32个样地开展实际调查, 其中16个观测到黑冠鹃隼。基于上述样地的气候与地理特征, 我们利用地理信息系统(geographic information system, GIS)、最大熵(maximum entropy, MaxEnt)模型和广义线性模型(generalized linear model, GLM)对黑冠鹃隼的生境利用特征进行了分析, 并预测了该县域内黑冠鹃隼的潜在适宜生境分布, 以期为黑冠鹃隼的保护工作提供理论依据。MaxEnt建模结果表明: (1)土地利用类型是限制黑冠鹃隼分布的最主要环境变量, 其中耕地和湿地类型的分布是重要的影响因子; (2)黑冠鹃隼分布也受到距道路距离和归一化植被指数的影响。GLM分析结果表明距道路距离对黑冠鹃隼的分布有显著影响。综上, 黑冠鹃隼更偏好土地利用类型为耕地或湿地、离道路较远、归一化植被指数较低的生境。

Abstract

Aims: Aviceda leuphotes is a second-class protected animal in China and a flagship species for birdwatching in many places. However, at present, the ecological research on A. leuphotes is very scarce, which significantly hinders our ability to implement targeted protection measures for this species. To address this issue, we conducted the study to analyze the characteristics of suitable habitats for the A. leuphotes and to predict potential suitable habitats in Mingxi County, Fujian Province, in order to provide a theoretical foundation for the conservation of the species.

Methods: In this study, 32 sample plots were selected for field survey by combining the initial records provided by the Mingxi Forestry Bureau, Fujian Province. Aviceda leuphotes were recorded in 16 sample plots. Using geographic information system (GIS), maximum entropy (MaxEnt) model, and generalized linear model (GLM), we analyzed the habitat suitability of A. leuphotes in Mingxi County, taking into account the climatic and geographic characteristics of each site.

Results: The results of the MaxEnt modeling showed that: (1) Land-use type was the most significant environmental factor restricting the distribution of the species, with cultivated land and wetland serving as the species' preferred habitats. (2) In addition, the distribution of A. leuphotes was influenced by the distance from road, as well as the normalized difference vegetation index. The results of the GLM also showed that the distance from road has a significant effect on the distribution of A. leuphotes.

Conclusion: Aviceda leuphotes preferred the habitat with cultivated land or wetland, far away from the road and low normalized difference vegetation index.
