    摘要:恢复河岸自然的植被缓冲带、构建生态河堤、恢复河道的自然形状和自然的河床物质组成可以改善河流生态系统的活力和生态服务功能。通过现场问卷调查,分析了河流周边的居民对于河岸带所提供的生态服务功能的认知及其对河岸带的植被类型、河堤的类型、河道的形状、河床的底质类型这些景观的偏好。结果发现参与者对于河岸植被缓冲带的各项生态服务功能的平均认知程度依次为:控制侵蚀(71.94%)、净化污染物(58.27%)、调控洪水(51.80%)、景观美学(46.76%)、休闲娱乐(43.17%)和维持生物多样性(28.77%)。河流周边居民及其职业群体对河岸植被类型、河堤类型、河道形状和河床物质组成的偏好也有较大的差异。研究结果可以为河流生态系统的保护和景观恢复设计提供有益的科学参考。

    Abstract:Some ecological management measures such as restoration of natural riparian vegetation buffer strips, building ecological riverbank, restoration of natural river shape and the material composition of riverbed can improve vitality and ecosystem services of the river ecosystem. The authors analyzed the perceptions of local residents to the benefits provided by riparian ecosystem, and their preferences for river landscape: such as riparian vegetation types, riverbank types, river shape and the material composition of riverbed. All participants' average cognitive percentage of ecological benefits from riparian vegetation was exhibited in the following order (from high to low): control soil erosion (71.94%), purify pollutant (58.27%), control flood (51.80%), landscape aesthetics (46.76%), and entertainment (43.17%) and wildlife's habitats (28.77%). The results also showed that local residents and their occupational groups also have different hobbies for riparian vegetation types, riverbank types, river shape and the material composition of riverbed. The results could provide useful scientific reference for restoration and landscape design of river ecosystems.
