哀牢山云南松林冬季鸟类群落与地理环境的关系

本文运用了群落相似系数、种间相遇机率指数、生态位分布型和食性研究,观测分析了同一山体两侧山坡八块样地冬季鸟类群落状况。在哀牢山西坡观测到鸟类44种,东坡观测到28种,其中13种为两坡共有。西坡除种多样性较高外,鸟类生态类型也与东坡有别。所有这些差别与哀牢山地理位置,西南季风影响所形成的东西坡植被和气候等环境因素有关。文章还分析了人类活动对森林演替和鸟类群落的影响。

RELATIONSHIP BETWEEN GEOGRAPHICAL ENVIRONMENT AND WINTER BIRD COMMUNITY IN THE YUNNAN PINE FORESTS IN THE AILAO MOUNTAIN, YUNNAN PROVINCE

This ornithological study was made in Yunnan Pine stands on both the western and eastern slopes of the Ailao Mountain. Eight sample plots that were used on the both for bird measurement and community analysis with coefficient of community and proportion of interspecific encounter, and distribution pattern of niches A total of 44 species were observed on the west side and 28 on the east with 13 being common to both sides. Besides the diversity of species being higher on the western slope, the type was different. All of the differences were results of vegetational and climatic differences determined by the topography of the Ailao Mountain and the effect of the southwest monsoon. This paper also analysed that the effect of human activities on the bird communities.
