摘要: 对八达岭林场16种林分类型水源涵养林物种丰富度、多样性、均匀度等多样性特征指标进行了研究。结果表明:在西沟油松林、杂木林和黑桦林中多样性指数变化表现为灌木>草本>乔木,在其他群落类型中多样性指数与丰富度指数一致;多样性指数在刺槐残次林、侧柏黄栌混交林、油松林、元宝枫林和华山松林中表现为草本层>灌木层>乔木层,华北落叶松林群落内部各层次物种多样性指数为灌木层>草本层>乔木层。

Abstract: We studied the diversity index of species richness,diversity and uniformity of 16 types of water conservation forests in Badaling forest farm.Results showed that the diversity index change in Xigou pine forest and shaw and black birch forest is in the form of shrub>herb>tree,in other communities it is same with the richness index;in secondary forest of Platycladus orientalis,Robinia pseudoacacia Cotinus coggygria mixed forest,pine forest,Acer truncatum and Huashan pine forest,the diversity index is in the order of herb layer>shrub layer>tree layer,the species diversity among all levels of larch forest community is shrub layer>herb layer>tree layer.

Key words: Badaling Forest Farm, water conservation forest, diversity, index
