摘要
为了明确露营活动对山地草甸植被的影响程度,运用典型样地法对武功山景区露营基地的草甸植被进行了调查与分析。结果表明:露营活动对山地草甸植被造成了较为明显的影响,而且不同区域的草甸植被,因承载的活动不同,露营活动强度也不同,其干扰程度也存在差异。受露营活动干扰后,草甸植被的外观特征变化较大,盖度减少率(CR)、高度减少率(HR)、植物区系组成变异度(FD)以及干扰指数(IVI)均明显增加;同时,草甸植被的多样性也受到了一定的影响,山地草甸的多样性指数(H')明显增加,均匀度指数(E)也略有增加,优势度指数(C)则明显降低。
In order to define the influence of the camping activities on mountain meadow vegetation,we investigated and analyzed the meadow vegetation of the camping base in Wugong Mountain scenic area by the method of typical sample. The results were as follows： camping activities on vegetation of mountain meadow caused significant effects. In different parts of the meadow vegetation,the intensity of camping activities were different because of different activities,and the degree of disturbance of the vegetation also showed difference. After interference of camping activities,the characteristics of the meadow vegetation changed obviously,their coverage reduction rate（CR）,height reduction rate（HR）,floristic dissimilarity（FD） and index of vegetation impact（IVI） all changed significantly. At the same time,the diversity of the meadow vegetation was also affected. Their diversity index（H＇） increased obviously,and even the degree index（E）. The advantage degree index（C） reduced obviously.
