遥感技术在青海湖地区生态环境脆弱性评价中的应用

Application of remote sensing technology in assessment of ecological environment fragility in Qinghai Lake area

本文从生态脆弱性成因入手,利用遥感技术较为全面地分析了青海湖环湖地区的生态环境脆弱性及其相关的影响因素.在评价各个影响因素的具体权重时,采用遥感技术采集的数据表达并评价,并以微度脆弱、轻度脆弱、中度脆弱与重度脆弱4个等级来进行程度区分,为青海湖环湖地区生态环境的环境评价提供了参考.

This paper comprehensively analyzes the ecological environment fragility in Qinghai Lake area and its related factors by using remote sensing technology from the causes of ecological fragility.In evaluating the specific weight of each influencing factor,the data collected by remote sensing technology are expressed and evaluated and the degree of fragility are distinguished：four levels micro,mild,moderate and severe fragility,which provide references for environmental evaluation of ecological environment in Qinghai Lake area.
