摘　　要：环青海湖湿地面积较大、类型丰富,是青海湖野生动物的重要栖息生境。利用遥感技术进行影像分类,并结合实地调查,建立环青海湖湿地资源分类系统,对该区域湿地资源的现状与分布特征进行研究。该区现有湿地4588.8352km2,以湖体为主。湿地类型有沼泽湿地、湖泊湿地和河流湿地,都为天然湿地,有河口湿地、湖滨湿地、盐碱化沼泽、季节性漫滩、沼泽、淡水湖泊、湖体(咸水湖泊)、河流8个亚类。结合环青海湖湿地的地貌特征、水文特征、植被类型以及生物状况,对青海湖典型湿地的成因和分布特点进行了详细描述,为青海湖湿地研究和保护提供依据。Wetlands around Qinghai Lake are large in area and diverse in type, they are important habitats for wildlife in Qinghai Lake. A classification system of Qinghai Lake wetland resources was developed using remote sensing for image classification in combination with ground survey. The system was used to study the current status and distribution pattern of wetland resources in the region. Classification analysis indicates that the area of wetlands in this region is 4,588.8352 km2, with the lake as the main body. The main types of wetlands were swamps, lakes and rivers. They were all natural wetlands, including estuarine wetlands, aquatic- terrestrial wetlands, salt-alkalization of marshes, seasonal floodplains, marshes, freshwater lakes, lake （saline lakes） and rivers. Combining with the characteristics of landform, hydrology, vegetation types and biotic conditions around Qinghai Lake, the distribution and genesis of typical wetlands in Qinghai Lake were described in details, providing a basis for future studies and conservation of Qinghai Lake.
