摘要:

生境选择是动物对环境行为适应的重要内容,生境丧失或片段化是目前大多数濒于灭绝的脊椎动物所面临的基本威胁。目前,针对高黎贡山地区羚牛的生态研究仍然较少,以云南高黎贡山国家级自然保护区独龙江流域的羚牛为研究对象,对其生境选择进行初步研究。结果表明:1)羚牛对硝塘的利用强度最高,其次为针阔混交林、竹林、草甸和落叶阔叶林;2)离硝塘的距离是影响羚牛生境利用强度的重要因子,其次为海拔梯度和平均海拔,离公路、水源和人便道的距离对羚牛生境利用强度影响不显著;3)研究区域设置的红外相机在硝塘中拍摄到的照片和视频最多,其次为针阔混交林,竹林、草甸和落叶阔叶林,再次验证了直接观察和痕迹观察的结果。因此,保护好独龙江流域的羚牛关键在于保护好硝塘以及附近连片的森林植被。

Abstract:

Habitat selection is an important part of animal's adaptation to environmental behavior,habitat loss or fragmentation is currently a fundamental threat to most endangered vertebrates. At present,there are still few ecological studies on takin in gaoligong mountain area. To study the habitat selection of takin in the dulong river basin in gaoligong mountains national nature reserve in Yunnan province. The results showed that takins have the highest utilization intensity of nitrate pond,followed by mixed needle-width forest,bamboo forest,meadow,and deciduous broad-leaved forest. The distance from the nitrate pond is an important factor affecting the habitat utilization intensity of the takin,followed by altitude gradient and average altitude,the distance from road,water source and human convenience has no significant influence on the utilization intensity of the habitat. The infrared camera set in the study area took the most photos and video in the nitrate pond,followed by mixed needle-width forest,bamboo forest,meadow,and deciduous broad-leaved forest,the results of direct observation and trace observation were verified again. Therefore,the key to protect the takins in the dulong river basin lies in protecting the nitrate pond and the adjacent forest vegetation.
