| 中文摘要: |
| 从2001年12月到2002年7月,在西藏东南部的慈巴沟自然保护区随机选择样线起始点,采用机械布点法设置了187个10m×10m的固定样方,记录了样方所在的植被类型与海拔、坡度等9个数量化因子,并分别在冬、春、夏三季检查样方是否被羚牛(Budorcas taxicolor)和鬣羚(Capricornis sumatraensis)利用。冬季,羚牛最喜爱杜鹃针叶林,而鬣羚仅喜爱箭竹针叶林。对9个数量化因子的判别分析表明,冬季,羚牛与鬣羚之间在栖息地利用上没有显著性差异。春季,羚牛最喜欢箭竹针叶林,其次是针阔混交林,而鬣羚最喜爱针阔混交林,其次是箭竹针叶林;判别分析显示种间达到了显著性差异;其中,坡度、坡向和水源距离3个因子的种间差异最显著。夏季,羚牛最喜爱高山草甸,鬣羚对针阔混交林、箭竹针叶林和杜鹃针叶林都喜爱;判别分析显示种间达到了显著差异,其中,海拔、隐蔽度、郁闭度、乔木密度和箭竹密度5个因子的种间差异最显著。本文从动物行为模式、食性和选择因子尺度等方面讨论了羚牛与鬣羚栖息地分化的机理及其共存的机制。 |
| 英文摘要: |
| Interspecific relationship of habitat use by Takin(Budorcas taxicolor) and Serow(Capricornis sumatraensis) was studied in South East Tibet,China between December 2001 and July 2002.A total of fourteen transects were set randomly along Cibagou Valley in the Cibagou National Nature Reserve,and 187 sample plots(10 m×10 m) were set every 250 m apart from the bottom to top position of the transects,the vegetation types of plots were recorded,and other 9 habitat quantitative parameters of them including altitudes and slops,etc,were also measured.We have also checked if there were new tracks of Takin or Serow in winter,spring and summer,respectively.Vanderploge and Scavia's selectivity index was used to assess Takin and Serow's habitat selection and found that Takin mostly preferred fargesia-coniferous forests while Serow mostly preferred fargesia-coniferous forests in winter.A discriminant analysis for 9 quantitative factors showed there was no significant difference between the habitat selection of Takin and Serow.In spring,Takin most preferred fargesia-coniferous forest,followed by broad-conifer mixed forest while Serow preferred theropencedrymion mostly,followed by fargesia-coniferous forest;the discriminant analysis for 9 quantitative factors showed significant differences between Takin and Serow,and the interspecific differences in selection on slope degree,slope aspect and distances from water were most significant.In summer,Takin mostly preferred Alpine meadow-shrubs,while Serow mostly preferred theropencedrymion,followed by fargesia-coniferous forests and rhododendron-coniferous forests;the discriminant analysis for 9 quantitative factors showed significant differences between Takin and Serow,and the interspecific differences in altitude,shelter,cover canopy,arbor density,bamboo density and vegetable type were most significant.Their coexistence mechanism and reasons for differentiation were discussed through food,behavior and other aspects. |
