黄柳沙障柠条网格在水土保持中的作用及特性

Roles and Characters of Salix lutea Sand Bars and Caragana korshinskii Networks in Soil and Water Conservation

沙地治理试验表明：采用黄柳沙障、柠条网格配置效果明显。即第一年春秋埋设黄柳沙障，第二年雨季在沙障间种植布设柠条网格，可明显减小侵蚀风速23％～57％，减缓沙丘移动；提高柠条成活率和保存率79％；促进天然植被恢复；还可以解决草原白灾饲料短缺问题。

The experimental results in sandland harnessments showed that using Salix lutea as sand bars matched with Caragana korshinskii networks make a good sand erosion controlled.Doing this at the spring and the autumn of the first year using Salix lutea as sand bars,at the raining season of the second year planting Caragana korshinskii networks between sand bars may obviously reduce wind rate to 23%~57% of it and delay the sandhill transformation. This may make Caragana korshinskii survive rate and preserve rate maintained to 79%,and not only promote the natural vegetation covery,but also resolve the forage grass difficiency problems in the grassland.
