STUDY ON THE MEASUREMENTS OF COMMU-NITY DIVERSITY IN LIANGSHUI OF XINGAN MOUNTAINS
【摘要】 <正> 群落多样性是反映群落功能的重要特征之一。它与种类组成的丰富度与均匀度两个参数有关。用其指数可以定量的比较不同群落结构特征。 鸟类群落多样性与其赖以生存的环境密切相关,它直接地反映了生境的多样性与稳定性状况。
【Abstract】 This study of the measurements of community diversity was made from 1981 to 1982 in Liangshui of Xingan Mountains.There are more than 160 species of birds in this area. And we ha—ye studied about 50 species, including summer migrants and residents.In this paper, statistical methods have been used to show the co-mmunity diversity of birds of the different biotopes. Using the Shan-non-Wiener’s H’=-sum from i=1 toS Pilgpi, we analyse the richness and eveness of birds, community.According to the observation between four biotopes,we learn that in this region the diversity of birds community in primary Korean pi-ne forestry is the greatest, H’=1.231.An analysis of the similarity and diversity index of the four birds community shows that degree of difference of birds community diversi-ty depends on the variations in vegetation.
