在3S技术的支持下,应用ArcGIS 9.3软件对延吉市1986、1996年的TM影像,2009年的ALOS影像3期影像进行解译分析,结合研究区自然生态环境特征,首次分析了23年间延吉市湿地的景观动态变化。并以此为基础,根据PSR概念模型,基于景观格局指数构建了延吉市湿地生态安全评价指标体系,并进行生态安全评价,综合评价结果为5.770左右,处于预警状态,急需加强对湿地的保护与管理。

Based on the 3S technology and ArcGIS 9.3 software,the interpretation（TM） in 1986,1996 and the ALOS images in 2009 of Yanji were analysised for quantitative variation of the landscape thereof,combined with ecological environment characteristics of Yanji City,the pattern change of wetlands was studied for the first time of Yanji City during the past 23 years.Based on the landscape pattern constructed wetland ecological index of Yanji safety evaluation On this account index system on the basis of the Pressure-Status-Response（PSR） concept model.The results showed that the safety of Yanji City wetland ecology is about 5.770,at the status of alert and need of strengthening the protection and management of this wetlands an issue.
