都陵河流域景观类型分化与繁殖鸟类群结构的研究

RESEARCH ON THE DIFFERENTIATION OF LANDSCAPE TYPES AND THE STRUCTURE OF BREEDING BIRD COMMUNITIES IN THE DULING RIVER BASIN

本文研究了都陵河流域景观类型的分化与繁殖鸟类群分布与结构的关系。该流域异质景观的空间格局一是叠加在地带性格局之内的垂直分异所形成的景观生态序列,其次是在水平方向上产生的景观类型分化。鸟类群的结构,深刻地反映了鸟类对景观类型分化而形成的空间结构的适应。

Beginning with landscape ecological analysis, the paper studies the relationship between the differentiation of landscape types and the distribution and structure of breeding bird communities in the Duling River basin. The spatial structure of the heterogeneous landscape in the basin shows mainly in two aspects: the landscape ecological series derived from the vertical differentiattion existing in zonal structure; the differentiation of landscape types derived from the horizontal. The structure of the bird communities in the basin reflects greatly the birds adaptation to the spatial structure derived from the differerentiation of landscape types. The structure of bird communities also reflects the degree of the differentiation of landscape types. The interrelationship between the differentiating process of landscape types and each bird community is studied with the dynamic view.
