摘要
风浪侵蚀导致湖岸崩塌和岸线后退,造成沿岸财产和土地资源损失,目前生态护岸已经成为一种趋势。香根草因其发达的根系、卓越的植物力学特性和强大的抗逆性,特别适合湖泊防浪护岸。本文结合监利县东港湖崩岸防治,介绍了湖岸香根草的种植方案和种植技术,采用水岸侧侵蚀模型计算了裸土湖岸和香根草生长湖岸在风浪作用下的侵蚀速率,结果表明,种植香根草可使湖岸的侵蚀速率减小90%以上。相对传统的刚性护岸,香根草护岸更加节省工程费用、更为环境友好。
Lakeshore slumping and recession resulting from wave erosion usually causes heavy loss of waterfront property and land resources.Ecological revetment is currently going to becoming the new trend of lakeshore erosion control.In this paper,vetiver is adopted to protect lakeshore against wave attack,because of vetiver' s surpassing root system morphology,phytomechanical properties and adaptability to adverse environment.Combined with the shore-protection works of Donggang Lake,the planting patterns and the planting techniques of the vetiver hedgerow are introduced.Furthermore,the shore erosion rates of Donggang Lake in different conditions are computed using lateral erosion model,the results show that when vetivers planted on lakeshore,the shore erosion rate can decrease more than 90%,and compared with rigid revetment,the ecological revetment is more economic and more environmentally friendly.
