In this paper, the basic principles and methods of community, ecology and Tourism comprehensive survey of tourism interference factors and community characteristics indicators based on, starting from the division of tourism disturbance, different interference strength shuttle the Shuibuya natural vegetation of woody plants the species composition of the community, floristic composition, species diversity, dominant species important value, niche, community appearance and impact of vegetation landscape aesthetic effect; explored shuttle the Shuibuya natural plant communities on tourism disturbance ecological response mechanism and response mode and changes in the index value of the main features of the natural vegetation on different tourism disturbance response, the results show: 1 shuttle Shuibuya tourism disturbance of the natural vegetation of the vertical distance of the strength and swim Road is closely related to the the the nearer distance swim Road, disturbance intensity Vietnam , farther from the tourism channel, the smaller the interference intensity. 2 tourist interference so the species composition of the community changes occurred in the family, genus and species level, the number of changes in the level, the general trend of moderate disturbance, mild interference is reduced. The slight interference communities as a control, to interfere with the role of the moderate 29.7% increase in the number of disturbed communities Branch, a 28.07% increase in the number of genera, a 37.70% increase in the number of species. The number did not change significantly and the the mild interference communities Branch, reduce the number of genera of 8.77%, a 8.20% reduction in the number of species. The 3 tourist disturbance on the floristic elements of communities, in the Division level performance increase as the the Pantropic world distribution type, the North Temperate type changes. Flora genus level, moderate interference so that the increase in the number of genera, 16 genera, and mild interference to reduce the number of genera 5 genera. The diversity of the community showed moderately disturbed communities gt; mild interference communities gt; slight interference with the community, the number of species of shrub layer is sensitive to tourism disturbance. 4 Tourism interference did not change the basic types of communities, is still a fir, pine as the main leaved mixed the tree layer Masson pine, fir dominance transaction. Other broadleaf total of priority species such as blue fruit, white oak and silver wooden mild, moderate interference communities positive the broadleaf species Liquidambar adenopoda and light Betula replaced. Interference not have much impact on the species composition of the dominant species of shrub layer. The 5 Dominant Population Niche Research shows that: in Joe, the shrub layer of fir and pine and shrub layer the wings Eurya, rat vector, Camellia larger niche breadth values, environmental adaptability, the use of resources more fully . But interference due to travel, tree layer of Masson Pine niche breadth in moderately disturbed communities reduce about 55% the shrub layer masson pine, rat vector, Camellia dominance has been positive species Rhus replaced. However, the original dominant species occupy the larger niche space pattern has not fundamentally changed. Community tree layer, only 20.8% of the species there are niche overlap description of the tree layer interspecific competition is not intense, strong competition for resources, species on Schima superba Daphniphyllum between acutissima, the acutissima with mice The vector, Liquidambar between. The the Viburnum shrub layer, blue fruit, mice vector, the mountain is covered with red, between light of Betula Symplocaceae, cherry, narrow leaves four photos of flowers and fir nine dominant populations due to biological characteristics and ecological habits similarity they appear on the utilization of the resources of a strong competition, niche overlap values ??above 0.5. 6 tourist disturbance on vegetation landscape appearance, showed moderate interference communities gt; the mild interference communities gt; slight interference communities. Compared with the control communities, the average moderately disturbed communities arbor tree, average diameter at breast height and average crown width were decreased compared with the control communities 1.81m, 1.62cm and 1.88m; while the mild interference communities impact is relatively small; vegetation landscape aesthetic effect also caused some impact, showed interference greater the intensity, the landscape is an important value to the lower trend. 7 shuttle Shuibuya natural plant communities on tourism disturbance ecological response mechanism is and tourism disturbance factors acting in the role of the object, so that the role of the object changes, so that the natural vegetation has undergone a series of changes at all levels. The shuttle Shuibuya natural vegetation response to different intensities of disturbance largely reflects the intermediate disturbance gt; the mild interference gt; slight trend interference.
