Abstract:: The research for ecological security and its affecting factors of oasis from 1999 to 2010 in the Yutian Oasis of the Keriya River Basin in Xinjiang Uygur Autonomous Region had been conducted by using the pressure-state-response (PSR) model. The results showed that the security integration index in Yutian Oasis presented an increasing trend from 1999 to 2010. Specifically, Yutian Oasis was in unsafe state from 1999 to 2005, and transformed from critical safety state to safety state from 2006 to 2010. Restrictive factor analysis showed that the tertiary industry of GDP, agricultural output value of unit cultivated land, grain yield per capita, highway mileage in domestic, farmers and herders net income per capita, urbanization degree, and proportion of cultivated area were the crucial limiting factors affecting ecological security of Yutian Oasis. In conclusion, ecological security of Yutian Oasis showed a good situation, and the evaluation results provided a scientific basis for maintaining and further improving ecological condition. Besides, the key restricted factors identified in this paper was consistent with the important demands of oasis economic, social and ecological construction, indicating that these factors could be primarily planned and constructed in terms of the oasis ecological security development.
