白冠长尾雉育雏期的栖息地选择

Brood Habitat Characteristics of Reeve's Pheasant (Syrmaticus reevesii) in Dongzhai National Nature Reserve

  • 摘要: 2001年4-8月,在河南省董寨国家级自然保护区对白冠长尾雉(Syrmaticus reevesii)育雏期的栖息地进行了调查。野外共遇见24个不同的家族群,平均大小为(2.96±0.35)只。白冠长尾雉的家族群主要在针阔混交林中活动,这些地方的坡向以东南方向居多、坡度较缓而坡位靠下,与林缘的距离大于60 m而与水源的距离通常小于30 m。逐步判别分析的结果表明,与林缘的距离、乔木胸径、灌木盖度、草本植物的种类和高度等是影响白冠长尾雉家族群栖息地选择的关键因子;植被结构,尤其是草本植物的特征,是影响家族群栖息地选择的主要方面。建议在对白冠长尾雉采取保护措施时,从提供丰富的食物资源和良好的隐蔽条件入手。注意保护现存栖息地,在育雏期保护好草本植物。

     

    Abstract: The brood habitat of Reeves Pheasant (Syrmaticus reevesii) was investigated in Dongzhai National Nature Reserve in Henan Province from April to August in 2001.Twenty-four broods were observed and recorded in the field.The brood size averaged 2.96±0.35.The broods preferred mixed conifer and deciduous forest with an aspect to southeast,a gentler slope,a lower gradient,and its distance to water being around 30 m and distance to forest edge being more than 60 m.By Stepwise Discriminant Analysis,the key factors related to habitat selection of the broods were distance to forest edge,diameter at the breast height of trees,cover of scrubs and types and height of grasses.Our results demonstrated that the status of grasses was a very important index to habitat selection of the broods of Reeves Pheasant;at the same time,habitat selection of the broods was strongly influenced by the vegetation structure.Therefore,the conservation of Reeves Pheasant should hammer at improving its food supply and shelter condition,preventing its habitat from deteriorating,and keeping grasses undisturbed,particularly in the brood rearing seasons.
