摘　　要：通过旅游活动对河南宝天曼国家级自然保护区陕西紫茎林干扰状态的对比研究发现:在干扰状态下其林地土壤的孔隙度降低,容重增加;土壤的有机质、全N、全K含量和酶活性下降,而全P含量增加;在其干扰区林下植物种类增加,植物区系组成趋于丰富,生活型改变;Shannon-W e iner指数增大。The impact of tourism disturbance on Stewartia shensiensis community in Baotianman Nature Reserve was studied. The results showed that tourism disturbance caused the decrease of soil porosity, increase of bulk density, decrease of the contents of organic matter, total nitrogen, total potassium and active enzyme, increase of phosphor- us. In the sites disturbed by tourism, the plant species increase, and the flora composition tended to rich, the lifeform of plant changed, and the Shannon-Wiener index increased.
