摘　　要：在辽河保护区选取19个调查断面,通过实地调查的方法对河岸带植被盖度、物种组成、河岸带宽度及土地利用现状进行了调研.结果发现,辽河河岸带植被盖度达到80%以上,但物种相对单一,主要以一年生草本植物为主;河岸带农田用地大量减少,辽河保护区河岸带生境趋于自然恢复状态.认为后期只要采用适宜的管理措施,逐步克服或消除人为的干扰压力,退化河岸带最终会由于生态演替的作用步入健康、良性发展,逐步恢复其自然生态功能.Nineteen regions were selected to investigate the vegetation cover ratio, species, width of riparian, and the status of land use. Results show that the natural vegetation cover increases to over 80%, but the species of vegetation are single, herbaceous species are mainly annual, the weeds accounts for a larger proportion of total herbaceous species, and the farmland significantly decreases, indicating that the native habitat of riparian area of Liaohe River is in a natural restoration state and tending to be a healthy riparian zone. Some proper management measures should take to reduce and eliminate the anthropogenic influence, then, the ecological function of riparian area will develop healthily, and gradually restore its natural ecological functions.
