摘要
太白山为我国著名的高山,是我国东经105°以东的最高峰,高达3767米。该山在地貌上具有高山深谷和冰川地形,同时在气候,植被、动物和土壤等方面具有典型的垂直分带现象。有关太白山鸟类的垂直分布,仅郑作新等(1973)作过简单叙述。为了能有效的利用鸟类资源,保护森林,满足当前对鸟类资源的规划和利用,作者于1982年6—8月,1983年6—9月,11—12月,1984年1、4月对太白山鸟类垂直分布的特点、原因.
This article discusses the vertical distribution of birds in Taibai Mts.There are 170 species of breeding birds,among them 112 species are residents and 58 summer migrants.Considered the basic characters of ecological distribution,we divide them into 3 ecological types:The species distributing in narrow vertical region,in sub-vertical region and in general vertical region.According to the simillar index of breeding birds between two relevant small zones,and simillar index of the community.No use the method of gathcrablc mathematics to divide the distribution of birds into 4 vertical zones:Plain-lon hill zone(500-1200m),mid-hill zone(1200-2400m),high-hill zone(2400-3300m),hill-top zone(3300-3767m).Excepting the species in narrow vertical region,the two other ecological types all have the phenomena of ventical migration.This due to the important affected by climaty to distribution of birds.
