摘要： 为了探明旅游活动对张家界国家森林公园植物多样性的影响，通过调查距离游道不同样带内的生物多样性变化，分析森林旅游开发对植物多样性的影响。结果表明，乔木层、灌木层、草本层三层中物种丰富度指数最低的是1号样带，其值分别为24、4、28，乔木层中2号样带物种丰富度指数最高为37，灌木层和草本层中物种丰富度指数最高的是3号样带，其值分别为7、48；乔灌草三层的Simpson指数与物种丰富度指数呈负相关关系，而Shannon-Wiener指数与物种丰富度指数呈正相关关系；乔灌草三层中的植物重要值大小排序为：3号样带 > 2号样带 > 1号样带；森林游憩对张家界国家森林公园植物多样性有显著影响。

Abstract: In order to investigate the effects of recreation on the plant diversity in Zhangjiajie National Forest Park, through the survey of the biodiversity change in different transect distance road, the authors analyzed the impact of tourism exploitation on plant diversity. The results showed that the species richness of tree, shrub and herb layer was the lowest in the transect 1 and the values were 24, 4 and 28, respectively. The species richness index of the tree layer was the highest in the transect 2 and the value was 37. The species richness index of shrub and herb layer was the highest in the transect 3 and the values were 7 and 48. There was a negative correlation between Simpson index and species richness index of tree, shrub and herb layer, while Shannon-Wiener index and species richness had a positive correlation. The order of important value of tree, shrub and herb layer was transect 3＞transect 2＞transect 1, and the forest recreation had significant effects on plant diversity in Zhangjiajie National Forest Park.
