摘要
我国中小河流的护岸工程只考虑工程的耐久性多采用混凝土护岸 ,忽略了河流的生态功能 ,破坏了河流的各种生态过程 ,导致河流污染严重 ,生态作用越来越小。本研究提出一种用芦苇恢复受损河岸的工程化方法 ,以解决恢复受损河岸时成本高 ,破坏了芦苇原生地的生态环境和芦苇不便于运输的问题。其优点在于 :在保证能够达到防止河岸崩塌及侵蚀的同时 ,在河岸工程设计中纳入生态学原理 ,创造出动植物及微生物能够生存的多孔隙河岸工程生态结构 ;可以减少对芦苇原生地的破坏 ,并且能够快速、大量繁殖芦苇幼苗 ,快速恢复受损河岸的芦苇群落及其生态环境 ;此方法在减少劳力、时间和成本的基础上 ,能够更容易恢复浅水带和河岸缓冲带芦苇群落 ,构建出一个芦苇繁茂的水域。
Only the practicability and durability was considered for revetment engineering on the medium and small river in China,Usually concrete was employing or reinforced and the ecological funetion of the river was neglected.It broke all kinds of ecological processes,polluted the river,and weakened the ecological function.An engineer method employing Phragmites australis for restoration of the damaged riparian was put forward.It lowered the cost,restored the original communities of P.australi,and was convenient for transportation.The method could not only prevent riparian from collapse and erosion but also introduce the ecological principle to the riparian engineering planning for creating the living space for plants,animals and micro-organism,which can restore the original communities of P.australi rapidly.The method offered an easy way to restore waterfront communities of P.australi using less labor,time and cost.
