旅游干扰对云丘山景区内植被的影响

选择云丘山景区为研究区域,以该区域的主要植被为研究对象,采用样方法对旅游干扰对云丘山景区内植被的影响进行了研究,共设置了40个乔木样方,并利用TWINSPAN聚类分析以及旅游干扰程度（TDD）对所取样方进行分析。结果表明：TWINSPAN聚类分类将景区内的植物群落划分为5个群系,其中、群系Ⅱ中伴人植物的优势度明显高于其它。干扰程度分析表明,在景区的40个乔木样方中,只有4个样方基本没有受到干扰,有3个样方受到中度干扰,其余的33个样方均为轻度干扰。TWINSPAN聚类分析科学合理地对旅游活动作用下植被景观的类型特征进行了分析。旅游干扰程度（TDD）直观地反映出各个样方所在地植被被干扰的程度,该研究结果可为旅游管理者提供一定的理论依据。

The influence of tourism disturbance on the Yunqiu mountain scenery vegetation

The Yunqiu mountain scenery is located at 35°44＇39. 5″ ~ 35°45＇50. 0″（ N）,110°59＇32. 30″ ~ 111°01＇39. 0″（ E）,and is the border of Xiangning,Zhaishan and Xinjiang. In the Yunqiu mountain scenery,the quadrat method of tourism disturbance on the vegetation in this area was used,40 tree quadrats were set up. The TWINSPAN（ two-way indicator species analysis） and the tourism disturbance degree（ TDD） were used. The results showed that in combination with the practical situation of survey area and TWINSPAN classification analyzing the plant community in the scenic spot into 5 types in 40 quadrats. Among of the 5 types,the Androphile dominance in Ⅱ was obviously higher than others. By traveling disturbance degree（ TDD）,there are 3 different degrees in the Yunqiu mountain scenery. 4 quadrats were in basically interference,3 quadrats were in moderate interference and the other 33 quadrats were in light interference.
