漓江沿岸水陆交错带景观调查与生态修复技术

[目的]分析漓江河流形态、水质状况、河岸植被群落结构,为漓江及其沿岸生态景观的修复提供参考依据.[方法]采用普查、重点样地调查、问卷调查结合查阅相关文献的方法,对漓江沿岸河岸形态、水质状况、植物景观现状进行分析,提出相应的生态修复技术.[结果]漓江沿岸由于人类活动的频繁,特别是自然河道的裁弯取直、渠道化、修筑硬质驳岸等人为因素的影响,自然植被受到严重干扰,阻碍了其生态服务功能的发挥.应用生态砾石床水质净化技术、植物浮岛技术、增加河岸植被缓冲带等一系列生态修复技术,使漓江沿岸驳岸渠道化现象得以改善,恢复了河流的蜿蜒曲折状态;沿岸残缺的植被得以修复,植物数量和种类有所增加,植物景观色彩和层次更加丰...

Summary:[目的]分析漓江河流形态、水质状况、河岸植被群落结构,为漓江及其沿岸生态景观的修复提供参考依据.[方法]采用普查、重点样地调查、问卷调查结合查阅相关文献的方法,对漓江沿岸河岸形态、水质状况、植物景观现状进行分析,提出相应的生态修复技术.[结果]漓江沿岸由于人类活动的频繁,特别是自然河道的裁弯取直、渠道化、修筑硬质驳岸等人为因素的影响,自然植被受到严重干扰,阻碍了其生态服务功能的发挥.应用生态砾石床水质净化技术、植物浮岛技术、增加河岸植被缓冲带等一系列生态修复技术,使漓江沿岸驳岸渠道化现象得以改善,恢复了河流的蜿蜒曲折状态;沿岸残缺的植被得以修复,植物数量和种类有所增加,植物景观色彩和层次更加丰富,物种多样性和植物群落结构已基本恢复.[结论]应用生态砾石床水质净化技术、植物浮岛技术、增加河岸植被缓冲带等一系列生态修复技术,可促进漓江旅游生态系统的可持续发展.

[Objective]To provide references for repairing and rebui｜ding the ecological landscape along the Li River, river morphology, water quality and bank vegetation population structure were analyzed. [ Method ] General survey, key plot investigation, questionnaire survey, literature consultancy, comparative analysis and comprehensive analysis were used to analyze river morphology, water quality and bank vegetation population structure. The corresponding ecological restoration technology was proposed. [Result]Due to human activities, river curve cut-off, channelization, and hard revetment con- struction, natural vegetation along Li River was severely interfered which led to the dysfunction of its ecological services. Through a series of ecological restoration techniques like the ecological gravel bed water purification technology, plant floating island, riparian vegetation buffer zone and so on, the coast re
