摘 要:唐代汴河兼具引水、分洪、灌溉、转漕、运输、植树绿化和改良土壤等多种良性生态效益。唐对汴河的浚治,缓解了汴河及黄河下游的压力,对于疏通航道、减少水患,保护生态环境具有一定的积极作用。而泥沙淤积,疏于修治则破坏了沿岸的自然环境,加上城市对森林资源的消耗,破坏了生态系统。The Bian Canal in the Tang Dynasty benefited ecology a lot in that it could be used to draw water,diverse flood,irrigate fields,transport goods,plant trees and improve soil and so on.Pressures of the Bian Canal and the downstream of the Huanghe River were alleviated because the Bian Canal was dredged by the Tang government,which ensured shipping,reduced flood and protected ecological environment.However,the natural environment along the banks is now destroyed because the riverbed is silted up by mud-sand.In addition,building cities leads to the consumption of forest resources,and thus causes great damage to ecological system.
