Abstract: The Rose-colored Starling (Sturnus roseus) is a long-distance migratory bird. Xinjiang is the breeding area of the bird in China. The Rose-colored Starling,which inhabit in the desert and semi-desert grassland along Tianshan Mountains in Xinjiang during May to August every year,can control locust significantly. Methods of regression analysis,least square,moving average were employed to analyze the temperature and precipitation changing trend in the habitat of the Rose-colored Starling during the past 50 years. The results showed as follows: (1) the average temperature of all the year,spring,summer,autumn and winter were 5.65±1.70 ℃(Altay,Tacheng,Ili,3.82±1.26 ℃,6.78±1.05 ℃,6.36±0.9 1 ℃,respectively),7.23±1.91 ℃(Altay,Tacheng,Ili,5.64±1.71 ℃,8.23±1.65 ℃,7.81±1.20 ℃,respectively),20.27±1.78 ℃(Altay,Tacheng,Ili,20.40±0.88 ℃,22.03±1.01 ℃,18.37±0.96 ℃,respectively),6.24±1.83 ℃(Altay,Tacheng,Ili,4.54±1.61 ℃,7.16±1.38 ℃,7.02±1.10 ℃,respectively)and -11.11±3.89 ℃(Altay,Tacheng,Ili,-15.23±2.62 ℃,-10.36±2.25 ℃,-7.75±2.15 ℃,respectively),respectively;and the average precipitation of all the year,spring,summer,autumn and winter were 266.23±103.37 mm(Altay,Tacheng,Ili,175.43±42.41 mm,238.26±45.78 mm,385.01±63.55 mm,respectively),72.18±36.33 mm(Altay,Tacheng,Ili,40.85±16.07 mm,67.14±18.11 mm,108.53±29.62 mm,respectively),96.12±49.56 mm(Altay,Tacheng,Ili,59.01±22.04 mm,75.28±21.14 mm,154.06±31.22 mm,respectively),62.57±23.74 mm(Altay,Tacheng,Ili,47.79±14.87 mm,58.08±14.94 mm,81.84±22.38 mm,respectively)and 35.22±17.69 mm(Altay,Tacheng,Ili,27.43±12.63 mm,37.59±14.69 mm,40.65±17.68 mm,respectively),respectively;(2)the average temperature in the habitat of the Rose-colored Starling during the past 50 years presented a significant increasing trend (P<0.01),and the increasing rate is 0.446 ℃/10 a;the increasing trend is significant in winter with a rate of 0.726 ℃/10 a (P<0.01),while smallest in summer with a rate of 0.295 ℃/10 a;the average precipitation presented a significant increasing trend (P<0.05),and the increasing rate is 10.90 mm/10 a,especially in winter and autumn with a rate of 4.50 mm/10 a (P<0.01)and 3.67 mm/10 a(P<0.05),while the average precipitation of spring and summer were stable (2.73 mm/10 a,1. 64 mm/10 a,respectively). At present,there is lack of study on characteristics of climatic change of Sturnus roseus’ habitat at home and abroad. The study showed that the Sturnus roseus’ habitat has suitable climate,especially in spring and summer,which is suitable for survival of the Sturnus roseus. On the other hand,the climate in the Sturnus roseus’ habitat is suitable for the growth of locust,which is the main food of the Sturnus roseus during its breeding season in Xinjiang. Suitable environments and enough foods might be one of reasons of habitat selection of the Rose-colored Starling. Therefore,climatic factors should be considered when establishing artificial attracted area to increase attract rate of the Sturnus roseus and enhance the control action of the Sturnus roseus to the locust.

Key words: climate change, temperature, precipitation, the Rose-colored Starling Sturnus roseus
