摘　　要：为查找摸清河流生态缓冲带范围内环境现状,结合河流生态系统特点,构建调查指标体系,并以蓟运河为例,基于北京三号卫星遥感数据和现场查勘,对缓冲带范围内的岸带结构和类型、生态系统、景观格局、服务功能等开展调查,结果表明:蓟运河左、右岸岸带类型中生态修复型岸带占比较重,部分河岸生态缓冲带宽度不足,两岸植被覆盖度和覆盖率整体不高,调查区域内平均生境质量仅为0.34,整体生境质量较差,破碎化程度较高。分析存在的生态环境问题,建议通过生境改造、沿河生态空间管控、水环境综合整治、强化农田面源污染防治等措施,在不影响河道行洪、排沥的条件下,尽可能恢复自然的生态多样性,因地制宜打造景观护岸生态带。In order to investigate the current environmental situation within the ecological buffer zone of the rivera survey index system was constructed.Taking the Ji Canal as an example,based on the remote sensing data of the Beijing No.3 satellite and on-site investigation,a survey was conducted on the structure and type of the shoreline,ecosystem,landscape pattern,etc.within the buffer zone The results showed that the ecological restoration type shoreline accounted for a relatively large proportion in the left and right bank shoreline types of the Ji Canal,and some of the shoreline ecological buffer zones were insufficient in width.The overall vegetation coverage and coverage on both sides were not high,and the average habitat quality was only 0.34.The overall habitat quality was poor.The study analyzed the existing ecological environment problems and suggested measures such as habitat renovation,ecological space control along the river,strengthening the prevention and control of non-point source pollution in farmland.Under the condition of not affecting river flood discharge and drainage,efforts should be made to restore natural ecological diversity as much as possible and create a landscape protection ecological belt according to local conditions.
