Effects of vegetation on the distribution of Ochotona curzoniae in the central Qinghai-Tibet Plateau under different study sites and slope locations
There were uncertainties in the research results concerning the effects of vegetation on the distribution of Ochotona curzoniae.In order to clarify the effect of vegetation on the distribution of Ochotona curzoniae,the number of burrows,plant spe-cies and vegetation coverage were recorded by means of line transmutation and sample method in Mountains Relong,Yanghu,Ri-do,and Gangbala,and different slope locations.In general,vegetation factors had no significant effect on the distribution of Ochotona curzoniae.However,there was a significant negative correlation between vegetation coverage and the number of Ochotona curzoniae burrows in the Relong area,and a significant positive correlation between the number of plant species and the number of Ochotona curzoniae burrows at the foot of the mountains.There were significant differences in the number of plant species among the study sites.Vegetation coverage and burrow number of Ochotona curzoniae were significantly different among slope sites.The results showed that the effects of vegetation on Ochotona curzoniae were different depending on the sample size,study site and slope location.
