【摘要】 运用物种丰富度指数、多样性指数和均匀度指数,对北京东灵山地区辽东栎幼林与成熟林进行了多样性的比较研究。结果表明:辽东栎幼林和成熟林两个群落物种组成基本相同,但一些物种在两群落种的优势程度不同。在乔木层,幼林的丰富度指数、多样性指数和均匀度指数大于成熟林;在灌木层,幼林的丰富度指数和多样性指数大于成熟林,均匀度指数没有规律;在草本层,成熟林的丰富度指数、多样性指数和均匀度指数大于幼林。群落总体多样性分析表明:成熟林丰富度指数大于幼林;幼林多样性指数大于成熟林;两群落的均匀度指数大体相同。更多还原

【Abstract】 Using the richness indices,diversity indices and evenness indices,we compare the species diversity of mature and immature forests of Quercus liaotungensis in Dongling Mountain,Beijing. The results are as follows:the species components of the two communities are basically the same, but the dominances of some species are different.In tree layer,the richness indices,diversity indices and evenness indices of immature forest are higher than those of mature forest;in the scrub layer,the richness indices and diversity indices of immature forest is higher than those of mature forest,and the evenness indices are not regular in the two communities;in the herb layer,the richness indices,diversity indices and evenness indices of mature forest are higher than those of immature forest.The analysis of the total diversity shows that the richness indices of mature forest is higher than those of immatureforest;the diversity indices of immature forest are higher than those of mature forest;the evenness indices of two communities are near.更多还原
