- 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.
