Abstract:: Drought is one of the environmental problems caused by climatic changes and human activity in arid and semi-arid regions. Study on regional environment aridity is very significant for regional eco-environment, water resources management and agriculture. In this paper, vegetation temperature condition index (VTCI) was used for drought monitoring in Keriya and Qira County, Xinjiang. From 2005 to 2010, study revealed a gradual increase in the extent of drought in the study area. Southern mountain area has the quick speed to drought, while northern area turns into drought slowly. During these five years, the average VTCI value of southern mountain area has decreased with the value of-0.210 0;the average VTCI transformation values of the central part of study area are 0.071 3 and 0.042 6, respectively, showing little trend to becoming wet;the lower river reaches of Keriya River is becoming a little drier with the Vegetation temperature (VTCI) transformation value of-0.045 6.
