摘要
木兰溪属平原冲积型河流,其河道岸坡大多是冲积泥沙在一定条件下落於、固结所形成,其冲刷崩塌属于河道水流与岸坡土体二元接触边界的稳定性问题;为打造绿色生态河流,总结了莆田木兰溪流域河道土体特点及潜在不稳定因素后,建议采用活树桩与堆石体的柔性固岸护坡方式进行河道绿色生态建设.采用活树桩-堆石体柔性方式进行保护河道岸坡,树根深根具有锚固作用,浅根有加筋作用;建立良性生态系统,最大限度地减少对原有环境和地形的影响和破坏;增添绿色景致,景观效应显著.
Mulan river is a plain alluvial river,the river slope is mostly alluvial silt in certain conditions,the formation of consolidation in fall,the stability problem of the erosion and collapse to river bank soil contact boundary for two yuan; to build a green ecological river,summarized the Mulan River Basin of Putian River Soil Characteristics and potential instability. Recommended the use of the tree stump and rockfill slope protection method for flexible solid bank building green ecological river. The stump of rockfill-a flexible way to protect the river slope,deep roots with root anchoring effect,shallow root reinforcement effect; the establishment of a healthy ecological system,minimizing the original environment and Terrain Influence and destruction; add green landscape,landscape effect significantly.
