【摘要】：旅游资源的开发和车辆碾压、游人践踏等已经严重干扰了甘南草原的生态环境。通过样方调查法,采用因子比较、回归分析等方法,分析了旅游活动对甘南桑科草原旅游点植被的影响程度。结果表明:桑科草原植被已经受到旅游活动的中度或重度干扰,干扰区植物物种数量、盖度、高度和完整度均受到明显的干扰。其中,旅游活动对植被的物种数量、高度和盖度的破坏程度分别为严重、较重和较轻。不同类型干扰区的植物生长和物种丰富度有明显差异。各类型干扰区的植物物种比率、植被盖度比率、草群高度比率和植物完整度指数分别与其对应的样方序号有明显的线性关系;旅游活动对游客游憩区、人行步道两侧和商店周围的植物生长指标影响范围分别为大、较大和较小;旅游活动对植被的高度和物种数量的影响较大,而对植被的完整度和盖度的影响较小。根据研究结果,提出旅游管理建议:规范草原上的游客观光步行通道和旅游设施点服务通道,控制草原上游客聚众活动区的数量和边界,定期更换游客聚众活动区位置,加强完善旅游区内警示牌系统。
[Abstract]:The exploitation of tourism resources, vehicle compaction and trampling have seriously disturbed the ecological environment of Gannan grassland. By means of sample investigation, factor comparison and regression analysis, the influence of tourism activities on the vegetation of Sangke steppe in Gannan was analyzed. The results showed that the vegetation of Moraceae steppe had been affected by the moderate or severe disturbance of tourism activity, and the number, coverage, height and integrity of plant species in the disturbed area were obviously disturbed. Among them, the damage degree of species number, height and coverage of vegetation caused by tourism activities were serious, heavy and light respectively. There were significant differences in plant growth and species richness among different types of disturbance areas. The plant species ratio, vegetation coverage ratio, grass height ratio and plant integrity index of different types of disturbance areas have obvious linear relationship with their corresponding sample number. The influence range of plant growth index on both sides of pedestrian walkway and around shops was large, larger and smaller, while tourism activity had a great influence on vegetation height and species number, but had little effect on vegetation integrity and coverage. According to the results of the study, the paper puts forward some suggestions on tourism management: standardizing the tourist walking passage and tourist facilities service channel on the grassland, controlling the number and boundary of the tourist gathering area on the grassland, and changing the location of the tourist gathering area regularly. Strengthen and perfect the warning sign system in the tourist area.
