天龙山旅游开发对植被的影响

Impacts of Tousist Development on Vegetation in Tianlong Mountains

以天龙山为例，采用敏感水平、群落景观重要值、物种多样性信息指数、旅游影响系数和伴人植物比例５项指标，对该区植被与旅游的关系进行了分析。结果表明：敏感水平与群落景观重要值和信息指数基本上成反比关系；旅游影响系数与伴人植物比例大小成正比，客观揭示了旅游对植被影响的规律性。利用这一方法评价旅游对植被的影响，具有可行性。

The relationship between vegetation and tourism industry in the Tianlong Mountains was analyzed in this paper. Five standards ─ sensitive level, community landscape importance value, information index of species diversity, tourist impact index and proportion of plants accompanied with mankind was used. The results show that sensitive level has inverse relation to landscape importance value and information index; tourist impact index is positively related to the rate of plants accompanied with mankind. These facts indicate the regularity of tourist has an impact on vegetation objectively. It is practical to use these above methods to appraise tourist impacts on vegetation.
