3.1 ǀ Differences in intensity of human disturbance
The intensity of different human activities differed significantly among the three study habitats: the mean number of automobiles every observation day passing through the HDH (297 ± 56.7) is significantly more than LDH (86.08 ± 10.44) and NH (4.00 ± 5.96) (Figure 2), besides, both motorcycles (100.83 ± 43.4 V.S. 54.58 ± 21.67 V.S. 14.00 8.43) and stray dogs (22.4 ± 7.2 V.S. 7.75 ± 3.77 V.S. 1.00 ± 2.00) showed the same trend too (Figure 2). Both high disturbance and low disturbance habitats suffered relatively intensity, persistent and evenly influences from automobile, motorcycle and dog during the whole active period of the species, (i.e. about 300 and 86 automobiles per observation day passing through the two disturbed habitats) (Figure 2, Table 1). However, in natural habitat, except for a dozen motorcycles passing by every observation day, there is seasonal fluctuation in the frequency and number of automobile and stray dog incursion into the habitat (i.e. about 12 automobiles per observation day from the end of June to early August only) due to the routine pasture rotation of local residents (Table 1).
