四川卧龙自然保护区斑羚生境偏好初探

Study on Habitat Preference of Chinese Goral (Naemorhedus griseus) in Wolong Nature Reserve, Sichuan

  • 摘要: 斑羚为我国广泛分布的林栖有蹄类,其生境选择与偏好是物种保护及管理的重要依据。2017年4月至2018年4月,在卧龙国家级自然保护区皮条河南岸,随机选择高海拔、中海拔及低海拔3个区域布设红外相机64台,调查斑羚在该区域的分布状况。同时,记录相机布设位点海拔、坡向、坡度、植被演替、植被类型、植被覆盖度、乔木盖度、乔木高度、灌木盖度、灌木高度、草本盖度、人为干扰12类生境因子,通过双样本卡方检验与Vanderloeg和Scavia选择系数,分析卧龙保护区斑羚的生境偏好。结果表明:卧龙保护区斑羚分布区域较广,分布海拔为1 500~4 500 m,但对海拔4 000 m以上区域回避,偏好于阳光充足的阳坡;偏好于植被覆盖度高的原始林,隐蔽性好的高乔木及食物充足的1~3 m高灌木区域;其次,斑羚对人为干扰敏感,明显逃避人为干扰区域。

     

    Abstract: Chinese goral (Naemorhedus griseus) is widely distributed in China, and its habitat selection and preference is an important basis for species protection and management. From April 2017 to April 2018, 64 infrared cameras were randomly installed in three areas of high altitude, middle altitude, and low altitude in the south bank of Pitiao river in Wolong National Nature Reserve, to investigate the distribution of Chinese goral in this area. In addition, 12 kinds of habitat factors, including altitude, slope aspect, slope degree, vegetation succession, vegetation type, vegetation coverage, arbor coverage, arbor height, shrub coverage, shrub height, herb coverage, human disturbance, were recorded. The habitat preferences of Chinese goral in Wolong Nature Reserve were analyzed by two-sample chi-square test and Vanderloeg and Scavia Index. The results showed that: (1) Chinese goral in Wolong Nature Reserve was widely distributed at an altitude of 1500 m—4500 m, but it avoided the area above 4000 m, and preferred sunny slopes. (2) Chinese goral preferred the old growth forest with high vegetation coverage, high trees with good concealment, and 1—3 m high shrubs with sufficient food. Chinese goral was sensitive to human disturbance, and obviously escaped from the human disturbance areas.
