摘　　要：呼伦贝尔湿地是重要的湿地生态研究区域,为研究该地区的景观格局演变,本文定义了一套基于MODIS影像的适用于描述景观变化的湿地分类系统,以呼伦贝尔湿地为研究区,利用2000和2020年的遥感影像获取2期湿地景观覆盖类型数据,运用转移矩阵、景观格局指数等方法分析景观类型、数量变化及格局特征,揭示呼伦贝尔湿地的景观动态变化。研究结果表明:2000~2020年间,呼伦贝尔湿地东部、东北部及西南部景观类型空间变化明显,草原景观、人工景观和沙地景观的面积减少,森林景观和湿地景观的面积增加,草原景观与其他景观转化明显,湿地景观和森林景观优势度较高,只有湿地景观的破碎化加剧。Hulun Buir wetland is an important wetland ecological research area. In order to study the evo-lution of landscape pattern in this area, this paper defined a set of wetland classification system based on MODIS image, which is suitable for describing landscape change. The Hulun Buir wet-land is taken as the research area, using the remote sensing image of 2000 and 2020 to obtain the wetland landscape cover type data, using the transfer matrix, landscape pattern index and other methods to analyze the landscape type and quantity changes and pattern characteristics, to reveal the dynamic changes of Hulun Beir wetland landscape. The results show that from 2000 to 2020, the spatial changes of landscape types in the eastern, northeastern and southwestern parts of Hulun Buir wetland are obvious. Grassland landscape, artificial landscape and sand landscape area decreased, forest landscape and wetland landscape area increased, grassland landscape and other landscape transformation are obvious, wetland landscape and forest landscape dominance are high, only the fragmentation of wetland landscape are intensified.
