小型水库、塘坝的土坝,采用生物工程护坡,可就地取材,节省投资,又能抵抗冰压力及冻胀的破坏,效果较好.生物工程护坡分死水区、风浪淘刷区和水土流失区3部分,而以草柳分护与草柳间护相结合的型式为最好.草种可就地取材,有芦苇、沿阶草(蒲草)、水葱、蔗草(三棱草)等。在死水区宜种水葱,风浪淘刷区可植柳、种芦苇和沿阶草等,水土流失区宜植陆草,并选择叶茎茂盛和根系发达的草种及美化草种。
Small reservoirs, dam dam dam, the use of bioengineering slope protection, can be drawn on the spot, save investment, but also to resist ice pressure and frost heaving damage, the effect is better. Bioengineering slope water, stormy area and soil erosion Area 3, while the grass willow care and grass willow combination is the best type of grass can be drawn on the spot, with reeds, along the step grass (Pucao), water onions, cane grass (Sanxiancao) and so on. In the deadwater area should be planted with water onions, wind and waves scouring area can be planted Willow species of reeds and along the step grass, soil erosion areas should be planted Lucao, and select leafy stems and root developed grass species and landscaping grass species.
