摘　　要：三门峡库区湿地地处黄河中游,是典型的多泥沙河流湿地。分析三门峡库区湿地土地利用类型的变化,对认识该地区整个生态系统的结构和变化具有至关重要的作用。基于1979~2017年8期Landsat系列遥感影像数据,对三门峡库区湿地土地利用信息进行了提取。选用单一土地动态模型,揭示了三门峡库区湿地各土地利用类型的年际演变特征,同时分析了其2017年年内演变特征,并从土地利用结构、经济社会效益、生态系统功能3个方面选取了17项指标,采用模糊层次分析法对三门峡库区湿地土地利用健康状况进行了评价。Sanmenxia reservoir area wetland is located in the middle reaches of the Yellow River. It is a typical muddy river wetland. It is very important to analyze the change of wetland land utilization types in Sanmenxia reservoir area to understand the structure and change of the whole ecosystem in this area.Based on the eight Landsat remote sensing image data from 1979 to 2017, the land utilization information of wetland in Sanmenxia reservoir area was extracted. Chose single land dynamic model to reveal the Sanmenxia reservoir area wetland interannual evolution characteristics of various land utilization types, and analyzed its evolution characteristics in 2017. From the land utilization structure, the economic and social benefits and the ecological system function, it selected the 17 indexes and evaluated the health situation of Sanmenxia reservoir area wetland land utilization by fuzzy hierarchy analysis.
