摘要
兴隆山自然保护区冬季鸟类共计34种,每种都采有标本并进行了食性分析,本文对该保护区6个鸟类群落进行了研究。沙棘—橙翅噪鹛群落多样性指数最高(H=3.6118),苔草、早熟禾—黄嘴朱顶雀群落多样性指数最低(H=1.5721).鸟类群落多样指数与群落中种的多少呈高度正相关(r=0.9632),(p<0.01),与种的个体分配均匀度指数呈显著相关(γ=0.8643,p<0.05),与优势度指数呈高度负相关(γ=—0.9814,p<0.01)。
There are 34 species of winter birds in Mt. Xinglong Nature Preserve by studying 6 communities of them, results obtained are as follows: there are the highest diversity index in Hippophae rhamnoides-Garrulax ellioti Community (H=3. 6118), and the lowest diversity index in Garex & Poa-Carduelis spinus community (H= 1. 5721 ). There is a highly positive relation (r= 0. 9632. p<0. 01) between the diversity index and the species number in the communities , and an obviously positive relation (r= 0. 8643, p<0. 05) between the diversity index and the evenness index of the individuals distributed and a highly negative relation (r=-0. 9814, p<0. 01) between the diversity index and the dominance index of the individuals
