摘　　要：运用RS和GIS技术,采用密度分割法对博斯腾湖小湖区4个时期的遥感影像NDVI值进行了解译。结果表明,近30a来博斯腾湖小湖区湿地环境问题严重,突出表现在小湖区湿地面积萎缩、沼泽景观持续退化、生物多样性减少、水质咸化等方面。针对湿地存在的环境问题,分析原因并提出相应的保护对策。With the support of RS and GIS,four images of the small lake in Bosten Lake have been interpreted on the basis of density segmentation theory and method.The results show that the small lake wetland in Bosten Lake has taken place serious environmental problems in recent three decades,for example the small lake wetland shrinkage,marshes deterioration,loss of biodiversity and water quality degeneration.The causes of environmental changes in Bosten Lake are analyzed and some protective countermeasures and suggestions are put forward.
