摘要:
沙棘"柔性坝"取得了良好的拦沙效果,为了进一步了解其对沟道土壤粒径分布的影响,试验测定了种植沙棘"柔性坝"的沟道内不同位置、不同深度的土壤颗粒级配,同时与一条未种植沙棘的小支沟进行了对比分析.结果表明:同未种植沙棘的沟道相比,由于沙棘的生长及其对坝内生态环境的逐渐改善,坝内淤积的泥沙整体上呈细化趋势,上游断面处此变化最为明显;受局部地形的影响,单个坝体内泥沙淤积无明显规律;由于沙棘"柔性坝"的存在,沟道内泥沙粒径从上游到下游呈递减趋势,且沙棘对粒径大于0.25 mm的粗颗粒泥沙具有较好的分选效果.
Abstract:
It has been validated that sea-buckthorn plant flexible dam has positive effects on sediment retainment.In order to further understand the influence of sea-buckthorn plant flexible dam on particle-size distribution of soil in the valley,the distributions of soil particle size at different locations in different depths are measured and analyzed in a valley with sea-buckthorn dam and another small valley without sea-buckthorn planted.Results show that compared with the valley without sea-buekthorn dam,the sediment becomes finer in the sea-buckthorn valley especially in the upper cross section of the reach due to the sea-buckthorn plant self and its improving effects on ecological environment,and that there is no obvious regularity of sediment deposition along a single sea-buckthorn dam as a result of local topographical influence.Further,it is observed that the sea-buckthorn plant flexible dam can diminish the sediment particle size from the upper reach to the lower reach along the valley,and also can effectively filtrate the sediment grain with particle size bigger than 0.25mm.
