Effects of tourism disturbance on the ecological stoichiometry characteristics of C, N and P of the vegetation and soil in Kanas Scenic Area

In order to explore the effects of tourism disturbance on the characteristics of carbon (C), nitrogen (N) and phosphorus (P) in the vegetation and soil in Kanas Scenic Area, the sample were divided areas into 4 zones: Ⅰ zone, Ⅱ zone, Ⅲ zone and Ⅳ zone according to the law of Kanas Scenic Area tourist activities (including hiking, horseback riding, roller compaction, the drift) and the distance of tourism channel, the number of attracted tourist, the conditions of vegetation and the C, N, P contents in vegetation and soil of these four different zones were measured. The results showed that the contents of N, P and C in both vegetation and soil decreased with the increase of the tourism disturbance intensity. The ratios of C∶N, C∶P and N∶P in vegetation and soil increased with the increase of the tourism disturbance intensity. Dynamic monitoring of C, N and P in vegetation and soil can reduce the negative impacts of tourism disturbance and contribute to the scientific and rational management of Kanas Scenic Area.
