摘要
采取定性与定量相结合的方法,根据湿地生态系统脆弱性评价指标体系,利用层次分析法和生态脆弱性指数模型,结合地理信息系统和遥感技术,对1986-2012年吉林省西部湿地生态系统进行脆弱性评价。结果表明,1986-2012年,吉林省西部湿地生态系统脆弱度平均为中度脆弱,其中,白城市、通榆县和乾安县的湿地生态系统脆弱度为强度脆弱;1986-2012年,吉林省西部湿地生态系统脆弱程度整体逐渐加重;从空间变化上看,1986-2000年,湿地生态系统强脆弱区由西部的通榆县向东部的松原市转移,研究区的西北部和东南部的湿地的生态脆弱程度逐渐加重,2000-2012年,研究区东部的湿地生态系统脆弱程度逐渐加重。
Both the quantitative and qualitative methods were taken in the study, according to the index system of vulnerability assessment of wetland ecosystem,using the analytic hierarchy process and Ecosystem Vulnerability Index model, combined with geographic information system（GIS） and remote sensing（RS） technologies, assessing the wetland ecosystem vulnerability in western Jilin province form 1986 to 2012. The results showed that, from 1986 to 2012, the wetland ecosystem vulnerability was moderate vulnerability in western Jilin province, these of Baicheng city, Tongyu county, Qian＇an county were intensity vulnerability. From 1986 to2012, the wetland ecosystem vulnerability overall showed a trend of gradually increase in western Jilin province. From 1986 to 2000, the intensity vulnerability zone of wetland ecosystem was transferred from Tongyu county in the western to the eastern part of Songyuan city, in the research area of the northwest and southeast,the wetland ecosystem vulnerability intensified gradually from 2000 to 2012, the vulnerability of wetland ecosystem in the eastern area of the study area was gradually increasing.
