| 摘 要： | 黄河三角洲湿地地区土地利用变化信息可为有关部门制定湿地保护和经济发展提供参考。本文选取2005、2009和2019年三时相黄河三角洲入海口周边，以及东营属地内黄河沿岸的Landsat 7 ETM＋遥感影像为数据源，采用监督分类方法研究土地利用类型，通过分析编码的变化判别黄河三角洲的土地利用转移情况，从而进行湿地变化动态分析。结果表明，研究区内2005—2009年湿地总面积减少了437 km2，呈减少趋势；2009—2019年湿地总体面积由2009年的930 km2变为2019年的998 km2，10年间研究区内湿地总体趋于稳定，并呈增长趋势；废弃三角洲海岸线发生缩减，黄河入海口位置发生变化。研究区内14年间土地利用类型转换频繁，湿地土地利用类型与非湿地土地利用类型形成动态转换系统。

| Abstract: | The information of land use change in the Yellow River Delta wetland area can provide reference for relevant departments to formulate wetland protection and economic development. In 2005, 2009 and 2019, Landsat 7 ETM + remote sensing images around the estuary of the Yellow River Delta and along the Yellow River within the territory of Dongying were selected as the data sources to study the land use types by using the supervised classification method, and to distinguish the land use transfer situation of the Yellow River Delta by analyzing the change of coding, and to carry out the dynamic analysis of wetland change. The results show that the total area of wetlands in the study area decreased by 437 km2 from 2005 to 2009, showing a decreasing trend. The total area of wetlands in the study area changed from 930 km2 in 2009 to 998 km2 in 2019, showing a stable and increasing trend in the past ten years. It was found that the coastline of abandoned delta decreased, and the location of the Yellow River estuary changed. In the study area, the land use changed frequently in the past of 14 years, and a dynamic conversion system was formed between wetland land use types and non-wetland land use types. |
