北京百花山旅游活动与植被环境的关系

通过实地取样并选取植被景观特征指标，分析百花山旅游植被景观特征与环境因子的关系。结果表明，自然因子对植被景观特征的影响较小，但各植被景观特征值大都与其有一定的相关性。在人文因子中，游径宽度和伴人种比值与生态效应值形成显著负相关，说明植被景观受人为活动影响较大。由此可见，山岳型景区开展生态旅游时必须加强生态旅游的规划和管理，尽可能减少人为因素对植被景观的影响。

Relationship between Tourism and Vegetation Environment of Baihua Mountain in Beijing

According to field sampling and choosing index of vegetation landscape features, the relationship between tourism and vegetation environment in the nature reserve were analyzed. The results showed that the vegetation landscape features were less affected by natural factors, but each vegetation landscape features and natural factors had some relevance. In human factors, the width of tourist road and proportion of species companying with human had a significant negative correlation with ecological effect value, it showed that human activities had a greater impact on vegetation landscape. In conclusion, when ecological tourism was developed in the mountain nature reserve, ecotourism planning and management must be strengthened, and the impact of human factors on the vegetation landscape should be reduced.
