| 摘 要： | 采用典型地段取样的方法，对河南龙池曼自然保护区旅游步道沿线的群落物种组成、物种种数、物种个体数、高度、盖度、频度进行了调查、采样，利用α－多样性指数，分析了旅游对物种多样性的影响。结果表明：旅游加大了环境异质化过程，使群落结构简化，物种组成减少，落的α－多样性指数、均匀度降低。

| Abstract: | An investigation about the species composition, individualnumber, highness, coverage and frequency of forest communities was made in Longchiman nature reserve in Henan province. In this paper, the methods of importance value and α-diversity index were measured. Base on these datum, the effects of tourism upon species diversity of forest community were analysied. The results show that tourism made the community structure simplified, reduced the species composition. Because of traveling, the landscape heterogeneity is bigger than before α-diversity ind ex of community decreased. |
