摘要
【目的】明确浙江乌岩岭国家级自然保护区黄腹角雉Tragopan caboti当前的种群分布范围,为评估保护工作效果及制定保护计划提供帮助。【方法】于2019—2020年,采用样线调查法、红外相机调查法对该保护区所有保护站黄腹角雉野外分布进行调查;通过实地调查并结合ArcGIS图像判读,综合分析分布点周边的森林植被类型、海拔高度及地形地貌等相关因素,判定黄腹角雉分布范围。【结果】共发现黄腹角雉分布点69个,涉及双坑口、碑排、黄桥、垟溪等4个保护站,分布面积依次为24.9、15.2、10.7和4.5 km^(2);黄腹角雉分布点主要在针阔混交林与阔叶林内,其他植被类型则较少;分布海拔为670~1550 m,比之前报道的800~1400 m的海拔范围要广;相比核心区域,黄腹角雉在阔叶林边缘区域的分布较多,种群分布表现出边缘效应;在低海拔分布地带及垟溪分布区未发现黄腹角雉的依赖性植物交让木Daphniphyllum macropodum,说明当前种群分布与交让木不具有完全的相关性;在4个分布区中,双坑口、碑排、黄桥3个分布区在地域上相连,其黄腹角雉种群有可能是乌岩岭原有种群繁衍与扩散的结果,而垟溪分布区与乌岩岭相距遥远,其种群则可以确定为独立存在的种群。【结论】经过长期保护,浙江乌岩岭国家级自然保护区黄腹角雉栖息地环境已在很大空间尺度上得到了恢复,栖息地片段化的状况得到明显改变,种群分布范围得到了较大扩展,说明该保护区长期以来所采取的保护措施已取得积极效果。而对于边缘效应等现象要进一步跟进研究,并在今后工作中采取科学的应对措施。
[Objective]This study aims to clarify the latest distribution range of Tragopan caboti population in Wuyanling National Nature Reserve of Zhejiang,so as to provide help for the evaluation of previous conservation work and development of future conservation plan.[Method]Transect survey and infrared camera survey were used to investigate the field distribution in all protection stations in the reserve from 2019 to 2020.Through field investigation and ArcGIS image interpretation,the distribution range of T.caboti was determined by comprehensively analyzing the forest vegetation type,altitude,topography and other related factors around the distribution point.[Result]A total of 69 distribution points of T.caboti were found in Shuangkengkou,Beipai,Huangqiao and Yangxi protection stations,with a distribution area of 24.9,15.2,10.7,and 4.5 km^(2) respectively.The distribution points of T.caboti were mainly in coniferous and broad-leaved mixed forests and broad-leaved forests,and less in other vegetation types.The altitude range was 670−1550 m,which was wider than the altitude range of 800−1400 m previously reported.Compared with the core region,the distribution of T.caboti was relatively large in the edge area of broad-leaved forest,and its population distribution showed edge effects.T.caboti-dependent plant Daphniphyllum macropodum was not found in the low altitude and Yangxi areas,indicating that there was no complete correlation between current population distribution and D.macropodum.Among the four distribution areas,Shuangkengkou,Beipai and Huangqiao were geographically connected,and the population of T.caboti might be the result of reproduction and diffusion of the original population in Wuyanling,while the distribution area of Yangxi was distant from Wuyanling,and its population could be identified as an independent population.[Conclusion]After long-term protection,the habitat environment of T.caboti in Wuyanling National Nature Reserve has been restored on a large spatial scale,the habitat fragmentation has been significantly altered,and the population distribution of T.caboti has been greatly expanded,which shows that the conservation measures taken in the reserve for a long time have achieved positive results.Further follow-up research should be carried out on phenomena such as edge effect and scientific countermeasures should be taken in future work.
