摘  要：
以新疆克里雅河流域于田绿洲为研究靶区,运用压力—状态—响应(PSR)模型,从时间尺度上对1999—2010年绿洲生态安全状况进行评价并进行影响因子分析。结果表明:于田绿洲生态安全综合指数大致上呈现递增趋势,1999—2005年处于不安全状态、2006—2010年由临界安全状态向较安全状态转变。限制性因子分析表明:影响于田绿洲生态安全的主要限制因子是第三产业占GDP比重、单位耕地农业总产值、人均粮食产量、境内公路里程、农牧民人均纯收入、城镇化程度、耕地面积比重。研究表明于田绿洲生态安全现状良好,评价结果将为维持及进一步改善生态状况提供科学依据。

摘  要：
The research for ecological security and its affecting factors of oasis from 1999 to 2010in 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 1999to2005,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.
