摘　　要：系统研究了河南龙池曼自然保护区旅游步道对群落物种组成、物种种数、物种个体数、物种盖度及重要值的影响。结果表明：旅游对步道两侧草本层、灌木层盖度的影响最大，对群落重要值的影响次之，对物种种数的影响较小，但对物种的组成成分有较大影响。在步道两侧的２ｍ处物种个体数最大；３ｍ以外，个体数逐渐减少。Developing of tourism is influencing the administration and protection of nature preserve in China. Being in charge of tourism vs. the effects of vegetation and diversity, an investigation was made in Longchiman nature reserve in Henan. In this paper, we discussed the effects of touring Path upon composition, individual of species, coverage, frequency and importance value. The results show that the largest effect caused by travelling is the coverage of herb and shrub, the second is the importance value, the third is the numbles of species. The largest numble of species individual is 2m apart from the travelling path.
