摘　　要：河岸带作为陆地与水生生态系统的过渡区域,发挥着重要的生态功能.重庆市广阳湾地处长江滨水带,具有得天独厚的地理优势和自然资源,但尚未得到很好的保护与发展.该研究通过实地调研,结合植物群落修复原则与具体的生态修复目标和要求,提出了广阳湾河岸带生态修复策略.①根据研究区内现有的不同植被类型,提出保留增补、优化提升和恢复重建3种植物群落构建模式;②根据鸟类、蝶类和蛙类等动物的生活习性,提出动物栖息地构建策略,并绘制典型生境模式示例图;③依据研究区消落带水位梯度,结合岸边地形和植被条件,提出相应的滨水植物配置参考.研究结果可以为不同地区的河岸带生态修复提供参考.Riparian zone,as a transitional region between terrestrial and aquatic ecosystems,plays an important ecological function.Guangyang Bay is located in the waterfront of the Yangtze River,with unique geographical advantages and natural resources,but has not been well protected and developed.In this study,based on the field investigation and in combination with the principles of plant community restoration and the specific objectives and requirements of ecological restoration,the ecological restoration strategies of the riparian zone of Guangyang Bay were proposed.①According to the different vegetation types in the study area,three plant community construction modes were proposed:reserving and supplementing,optimizing and upgrading,and restoring and rebuilding.②According to the living habits of birds,butterflies,frogs and other animals,the habitat construction strategy was proposed,and the typical habitat model sample map was drawn.③According to the water level gradient of the water-level-fluctuation zone in the study area,combined with the shore topography and vegetation conditions,the corresponding waterfront plant configuration reference was proposed.The results can provide reference for riparian ecological restoration in different areas.
