旅游活動對甘南草原植被的影響——以�？撇菰糜吸c為例
發(fā)布時間：2018-07-26 11:14
【摘要】：旅游資源的開發(fā)和車輛碾壓、游人踐踏等已經(jīng)嚴(yán)重干擾了甘南草原的生態(tài)環(huán)境。通過樣方調(diào)查法,采用因子比較、回歸分析等方法,分析了旅游活動對甘南�？撇菰糜吸c植被的影響程度。結(jié)果表明:桑科草原植被已經(jīng)受到旅游活動的中度或重度干擾,干擾區(qū)植物物種數(shù)量、蓋度、高度和完整度均受到明顯的干擾。其中,旅游活動對植被的物種數(shù)量、高度和蓋度的破壞程度分別為嚴(yán)重、較重和較輕。不同類型干擾區(qū)的植物生長和物種豐富度有明顯差異。各類型干擾區(qū)的植物物種比率、植被蓋度比率、草群高度比率和植物完整度指數(shù)分別與其對應(yīng)的樣方序號有明顯的線性關(guān)系;旅游活動對游客游憩區(qū)、人行步道兩側(cè)和商店周圍的植物生長指標(biāo)影響范圍分別為大、較大和較小;旅游活動對植被的高度和物種數(shù)量的影響較大,而對植被的完整度和蓋度的影響較小。根據(jù)研究結(jié)果,提出旅游管理建議:規(guī)范草原上的游客觀光步行通道和旅游設(shè)施點服務(wù)通道,控制草原上游客聚眾活動區(qū)的數(shù)量和邊界,定期更換游客聚眾活動區(qū)位置,加強(qiáng)完善旅游區(qū)內(nèi)警示牌系統(tǒng)。
[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.
