摘　　要：目的研究遥感(RS)、地理信息系统(GIS)、全球定位系统(GPS)相结合的3S技术在湿地生态系统动态监测与评估过程中的应用,并证明其有效性和可行性.方法以福田红树林自然保护区为例,通过3S技术获取2006—2015年间3个时相原始的遥感影像数据,并进行预处理;建立数据库,提取湿地信息;结合实地观测对提取的数据进行纠正;根据各项湿地生态系统评价指标对研究区湿地的生态系统的湿地面积变化、空间分布变化、植被覆盖率变化、景观格局变化进行定量统计分析.结果 3S技术实现了对福田红树林自然保护区部分范围的湿地生态系统近10年的动态监测,得到了湿地生态系统的现状和变化趋势,提高了监测的自动化、智能化水平.结论利用3S技术可以实时、全面地掌握湿地生态系统的动态变化,是对湿地进行保护和管理高效而准确的方法.This paper aims at study on the application of 3S（ RS、GIS、GPS） technology in the dynamic monitoring and assessment of wetland ecosystem. The M angrove Nature Reserve of the Fukuda was taken as an example. RS image rawdata of three years from 2006 to 2015 were got by using RS software. Database was established by using GIS software and wetland information was extracted. Then the extracted data were corrected by the GPS. Finally,changes of area,spatial distribution,vegetation cover and landscape pattern were quantitative statistical analysis according to the evaluation index of wetland ecosystem. By 3S technology the dynamic monitoring of Fukuda M angrove Nature Reserve in 10 years was implemented to get the status and changing trend of the wetland ecosystem. So the automation and intelligent level of monitor was improved. It shows that dynamic changes of wetland ecosystem can be real-time and comprehensively mastered by 3S tech-nology. So3 S technology is an effective and accurate way on protecting and managing wetland.
