Abstract: We conducted a survey on l9 sample route of 818 km long，them eanvertical distance from the watching spot to animals was 248.3 m ，the total area of the sample route was 405.8 km²,and observed 62 groups Gazelle containing 221 individuals in the distribution (north to Tianshan M t．)of Gazella subgutturosa saireasis of north Xinjiang from August to September in 1992 and September in 1998 .The meandensity of the sample route was 0.7l±0.17 Individuals／km²，the maximun density was l.85 Individuals／km² and 0.14 Individuals／km² .Tlie region of high density was proved to lie in the southern edge of hungaer basin．For the statistics on 16 sample route of 37 groups which Can be classified to different age and sex,113 Individuals were observed,among them there were 39 females,4l males and 33 juveililes .Group size ranged from I(male group)to 12 (mixed group)Individuals；the mother—groups were 16 with the mean 3.1 Individuals/group; male groups were 12 with the mean 2 Individuals／group; female groups were 3 with the mean 2.3 Individuals／group; mixed groups were 6 with the mean 5.3 Individuals／group．Thesex ratio of female to male was 1:1.05, adult to fawn was 2.4:1.According to the statistics of 8 sample route of l6 mother-fawn groups，there were 21 females and 29 juveniles，and the ratio of female to juvenile was1:1.4. In the survey of 8 saple route of 230 km long，the mean vertical distance was 299m ,the area was 116 km ,in the distribution (south to Tianshan Mt) of G.s.yarkantensis of south Xinjiang in Febuary and October 1993, we observed 17groups Gazelles containing 51 individuals．The population density ranged from 0.1 Individuals／km² to 1.67 Individuals／km² with the mean density of 0.57±0.26 Individuals/km² ．The sample route of high density lied in the northern the of Talimu Basin.
