中文摘要	为客观评价叶尔羌河平原绿洲生态安全警情,基于PSR-EEES模型构建适合研究区的指标评价体系,运用综合指数法测度19902016年叶尔羌河平原绿洲生态安全预警状态,并结合GM(1,1)模型预测20262032年区域生态安全态势。结果表明:1)19902016年叶尔羌河平原绿洲生态安全综合预警指数总体呈增长趋势,综合预警指数从0.255 8增加到0.551 6,生态预警状态由重警转为中警,预警指示灯由橙色变为黄色;2)GM(1,1)预测模型显示,20262032年研究区生态安全态势进一步好转,生态安全预警值从0.726 2上升到0.891 3,安全状态由较安全转向安全,安全等级从Ⅱ级上调为Ⅳ、Ⅴ级;3)空间上各县生态安全预警状态差异明显,研究初期西南部地区生态安全状态优于中东部地区,2016年呈现出中部高、东北-西南部低的态势。研究显示,近26年叶尔羌河平原绿洲生态环境得到了一定恢复,但绿洲内部各县生态预警状态差异明显,生态文明建设工作任重而道远。
英文摘要	In order to objectively evaluate the ecological safety warning situation of Yarkant river plain oasis,an index evaluation system based on the PSR-EEES model suitable for the study area was constructed.The comprehensive index method was used to evaluate the ecological safety warning state of the Yarkant river plain oasis from 1990to 2016,and the GM(1,1)model was combined to predict the regional ecological safety situation from 2026to 2032.The results showed that:1)The comprehensive index of ecological safety early warning in Yarkant river plain oasis from 1990to 2016showed an overall increasing trend.increasing from 0.255 8to 0.551 6,and the ecological warning changed from heavy alarm to moderate alarm with the warning indicator light changed from orange to yellow;2)The forecast model of GM(1,1)showed that the ecological safety situation of the study area in 2026-2032was further improved,ecological security warning value increased from 0.726 2to 0.891 3.A more secure statu emerged,and the safety grade was upgrated from gradeⅡto gradeⅣandⅤ;3)The status of ecological safety early warning in different counties was obviously different.In the early stage of the study,the ecological safety state in the southwest was better than those in the central and eastern regions.In 2016,it showed a trend of higher in the center area and lower in the northeast and southwest areas.In conclusion,the ecological environment of Yarkant river plain oasis was restored to some extent in the past 26years.However,the state differences of ecological safety early warning in different counties were obviously indicating that the construction of ecological civilization has a long way to go.
