| 摘 要： | 黑颈长尾雉Syrmaticus humiae取食地的观察于2005年3月11日至4月16日在云南哀牢山国家级自然保护区南华片进行，搜寻到取食地15个，相应设15个对照样地。调查和测量它们的22个变量因子。比较取食地与对照样地中各变量，t-检验和Mann-Whitney U-检验结果表明，植被特征的乔木密度、灌木密度、灌木层盖度、草本层盖度和枯落物盖度等5个变量因子差异极显著，乔木层盖度差异显著；食物因素的种子密度和土壤动物密度2个因子差异极显著。主成分分析结果显示，黑颈长尾雉优先选择的取食地具有以下特征：灌木、乔木、草本和枯落物层发达，地面种子食物资源丰富，远离干扰源。黑颈长尾雉围绕解决繁殖期取食安全和营养需求来优先选择取食地变量因子，即选择互补型的高灌木或乔木盖度、壳斗科Fagaceae植物种子和土壤无脊椎动物丰富的区域作为取食地。表3参26

| Abstract: | Hume's pheasant(Syrmaticus humiae) is an easy to endangered species.The object is to effectively protect Hume's pheasant in its breeding season.Foraging sites of Hume's pheasant were surveyed from March 11 to April 16,2005.Fifteen foraging plots were established along with the same number of control plots and 22 variables were measured.A t-test and Mann-Whitney U-test to compare variables in forage and control plots showed significant differences(P<0.01) for the five vegetation characteristics of tree density,shrub density,shrub coverage,herbage coverage,and leaf litter coverage;crown canopy was also significantly different(P<0.05).Additionally,significant differences(P<0.01) for two food characteristics,namely seed density and density of edaphic animals,were noted.A principal component analysis indicated that fine shrub,tree,herb,andlitter layers;abundant seed resources in the understory;and being far away from human disturbance characterized optimal foraging sites for Hume's pheasant.Thus,when selecting a foraging site in the breeding season,safety and nutrition were the pheasants' major concerns.Therefore,they would choose foraging habitats with strong camouflage cover from shrubs or trees with ample food sources in the understory,such as seeds from the Fagaceae family and edaphic animals.Ch,3 tab.26 ref.] |
