摘要 滨海湿地是世界湿地的主要组成部分。三角洲低地环境中的土地覆盖和植被测绘因地貌的快速而显着的变化而变得复杂。遥感为沿海土地覆盖分类和景观分析提供了重要工具。本文的研究地点是位于中国山东省黄河口的黄河三角洲自然保护区（YRDNR）。黄河三角洲是世界上发展最快的三角洲之一。长三角国家级自然保护区于1992年被列为国家级自然保护区。本文的目的有两个：研究长三角国家级自然保护区的土地覆盖状况，以及考察其被宣布为自然保护区以来的土地覆盖变化。 YRDNR 的土地覆盖和植被制图是使用 1995 年获取的多光谱 Landsat Thematic Mapper (TM) 图像绘制的。土地覆盖和景观特征在辅助 GIS 的帮助下进行了分析。采用1991年土地利用调查数据与Landsat分类图进行比较。我们的研究结果表明，1992年之后，长三角自然保护区经历了显着的景观变化和环境改善。
Abstract Coastal wetland is a major part of wetlands in the world. Land cover and vegetation mapping in a deltaic lowland environment is complicated by the rapid and significant changes of geomorphic forms. Remote sensing provides an important tool for coastal land cover classification and landscape analysis. The study site in this paper is the Yellow River Delta Nature Reserve (YRDNR) at the Yellow River mouth in Shangdong province, China. Yellow River Delta is one of the fastest growing deltas in the world. YRDNR was listed as a national level nature reserve in 1992. The objectives of this paper are two fold: to study the land cover status of YRDNR, and to examine the land cover change since it was declared as a nature reserve. Land cover and vegetation mapping in YRDNR was developed using multi‐spectral Landsat Thematic Mapper (TM) imagery acquired in 1995. Land cover and landscape characteristics were analyzed with the help of ancillary GIS. Land use investigation data in 1991 were used for comparison with Landsat classification map. Our results show that YRDNR has experienced significant landscape change and environmental improvement after 1992.
