　　摘 要：為保護黃河三角洲濕地生態系統，掌握濕地變化趨勢，以1986年—2018年間15 a衛星遙感影像為數據源，通過ERDAS 9.0和ArcGIS 10.3平臺開展黃河三角洲濕地遙感解譯，建立土地利用轉移矩陣，分析黃河三角洲濕地面積和分布格局及變化特征。結果顯示：濕地是黃河三角洲主要生態系統類型，主要分布在沿海區域，與20世紀80年代相比，黃河三角洲濕地面積整體下降，其中自然濕地萎縮嚴重，人工濕地增長迅速，濕地面積和結構均發生較顯著變化，而區域土地資源開發是濕地結構變化的主要因素。研究成果表明：基于遙感解譯，采用E RDAS 9.0和ArcGIS10.3平臺能快速獲取較多濕地類型信息，提高提取精度，可為大范圍土地利用分類研究提供方法參考。

　　Abstract: In order to protect wetland ecosystem of the Yellow River Delta and understand the evolution trend of wetland, remote sensing images from 1986 to 2018 are used as data sources to carry out remote sensing interpretation of the Yellow River Delta wetland through ERDAS 9.0 and ArcGIS10.3 platforms, land use transfer matrix is established. The area, distribution and changing patterns of wetland are analyzed. The results show that wetland is the main ecosystem type in the Yellow River Delta, mainly distributed in the coastal area. Compared with the 1980s, the overall wetland area in the Yellow River Delta decreased, in which the natural wetland shrank seriously, while the constructed wetland increased rapidly, leading to a significant change in wetland area and structure. The development of regional land resources is the main factor of wetland structure change. The research results also show that based on remote sensing interpretation, ERDAS 9.0 and ArcGIS10.3 platforms can quickly obtain more information of wetland types and improve the extraction accuracy, which can provide for large-scale land use classification research.
