对河道生态护岸的思考

Thoughts on river ecological embankment

在河道治理工程中,为了保证河道岸坡的稳定,通常采用硬质护岸或生态护岸。通过对江苏省内8条河道治理工程中的各种护岸长度的统计,结果表明硬质护岸的比例远超过生态护岸。对硬质护岸和生态护岸本文通过3个方面进行比较,包括工程效果、造价和环境影响,说明生态护岸的优势以及硬质护岸的不足之处。同时为河道整治工程中采用生态护岸提供了一些建议。

In order to ensure the stability of river bank slope in river control project,rigidity revetment or ecological revetment are usually adopted.Through the statistics of various revetment lengths in the eight river control projects in Jiangsu Province,the results showed that the proportion of rigidity revetments was far surpasses that of ecological revetments.Through the comparison of the three aspects of rigidity revetment and ecological revetment,including the engineering effect,cost and environmental impact,the advantages of ecological revetment and the shortcomings of hard revetment were illustrated.At the same time,some suggestions on ecological bank protection in river regulation project were provided.
