摘　　要：采用样带调查法,对雾灵山自然保护区华北落叶松林、油松林、白桦林的物种种类、物种个体数、高度、盖度、频度等因子进行了调查。利用α-多样性指数分析了旅游干扰对植被的影响。结果表明:随旅游强度增大,物种多样性、均匀度及盖度降低。其中Simpson指数降低了8.7%,JSi降低了7.5%,Shanno-Winner指数降低了16.4%,JSW降低了10.9%,盖度降低了50%以上。开展生态旅游虽然对植被产生了一定的影响,但这也是各个旅游景区普遍存在的现象,并且在雾灵山这种影响并不大,主要集中在距离道路3m以内,对再远的地方基本没有影响。A belt transect investigation about the species composition, individual number, height, coverage and frequency was made for larch(Larix principis-rupprechtii) forest, Chinese pine (Pinus tabulaeformis) forest and birch(Betula platyphylla) forest in Wuling Mountain natural reserve. In this paper, with α-diversity index, the effects of tourism upon the vegetation of forest community were analyzed. The results showed that the species diversity, the degree of homogeneity and the coverage were reduced with the tourism intensity enhancing.There were 8.7%,7.5%,16.4%,10.9% individual decrease in Simpson, J_(Si),Shanno-Winner,and J_(SW),and the coverage was made degraded by at least 50 percent.Although ecotourism has obvious effect on vegetation,the phenomenon exists in every Scenic Spot prevalently.The influence of ecotourismonWulingMountainwasnotserious,whichmainlyconcentratedwithin3mawayfromtheroads.
