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).
