中文摘要	为研究干旱区绿洲生态安全,采用2010年新疆地区TM影像和HJ1A-CCD1影像提取新疆生产建设兵团(简称新疆兵团)部分自然组分数据,结合气象、环境和社会统计数据,在国内外已有研究的基础上,基于压力-状态-响应(PSR)概念模型,选取25项指标,构建新疆兵团生态安全评价指标体系,利用层次分析法确定各项指标的权重,以师为评价单元,采用生态安全综合安全指数(ESII)对新疆兵团生态安全进行定量评估。结果表明:全兵团Ⅱ级较安全区域有4个师,Ⅲ级临界安全区域有7个师,Ⅳ级较不安全有2个师,分别占全兵团国土面积的32.84%、56.47%、10.69%。依据评价结果,可为新疆兵团的生态建设及管理提供科学依据。
英文摘要	Ecological security is one of the foundations of regional security,and is the basis of sustainable development. Regional ecological security includes the natural ecological security,the economic ecological security and social ecological security. Fragile ecological environment and oasis desertification make the arid area oasis ecological security have the important position,and it is an important field where the regional ecological security evaluation theory can be constructed. Ecological security problems of arid areas oasis is typical and highlighted,it is ideal object for regional ecological security assessment. Xinjiang Production and Construction Corps (short for Xinjiang Corps) is located in arid area oases of Xinjiang. And it is one of the largest reclamation farm in China. It is necessary to study ecological security of Xinjiang Corps. To study the eco-security of arid areas oases, some data of the natural component in Xinjiang Corps can be extracted from TM and HJ1A-CCD1 image of 2010 in Xinjiang, and combined with the weather,environmental and social statistics,the ecological security index (ESII) system includes 25 indices for Xinjiang Corps and was built up with the pressure-state-response (PSR) model. The weights of the indices were determined by analytical hierarchy process (AHP) and using integrating index evaluation method, different division was taken as a case study and its ecological security situation was assessed quantitatively: The results show as follows : (1) As far as ecological pressures,PI of Division 7 is the weakest,PI of Division 14 is the strongest. As far as the system state,SI of Division 4 is the best,SI of Division 13 is the worst. As far as the system response,RI of Division 8 is the best, RI of Division 14 is the worst. (2) there are 4 Divisions which are II security (Division 4,Division 6,Division 7,Division 8,ESII is 0.555 10.598 6,0.563 9 and 0.625 5 respectively) ;there are 7 Divisions which are III security (Division 1,Division 2, Division 3,Division 5,Division 9, Divisionl0, Division 12,ESII is 0.517 6,0.515 2,0.473 6,0.504 6,0.515 3,0.466 7,0.504 2 respectively);there are 2 Divisions which are IV security (Division 13,Division 14,ESII is 0.385 8 and 0.364 2),they account for 32.84%, 56.47%,10.69% of land area of Xinjiang Corps. (3) The regional ecological security can be effectively evaluated by using RS, GIS and AHP. Finally, based on evaluation results and status of Xinjiang Corps, this paper puts forward some suggestions on the construction and the management of the ecological environment.
