火山口国家森林公园旅游活动影响下植被景观评价分析

Impacts of Tourist Development on Vegetation in Huoshankou National Forest Park

通过实地调查取样,采用敏感水平、群落景观重要值、物种多样性信息指数、阴生种比值等指标对火山口国家森林公园进行研究。分析了旅游活动对植被景观的影响,其相关性表明:距游径的水平距离愈远,敏感水平愈低,景观重要值愈大,物种多样性信息指数愈大或者稳定。这些指标的变化趋势和其相互关系相吻合,且与植被现状大体一致,反映了整个森林公园植物群落的旅游价值及其生态环境质量。

Forest park is a good place for eco-tourism.The impacts between eco-tourism and vegetation environment is studied too late.Although it has been developed quickly in the world,it has not been well in China.The impacts between tourist development and vegetation environment Huoshankou national forest park is analyzed.The correlation among evaluating indices shows that the farther the level distance is,the lower the sensitive level is,the larger landscape important value and information index of species diversity are,the smaller tourism influencing index is.
