207国道植物再生沙障防沙治沙试验研究

Experiment on Sand Prevention and Control with Plant Sand Barrier along 207 National Highway

207国道90—100 km段公路沙害治理中,采用黄柳在流动沙丘迎风面上设置积沙、聚沙带——植物再生沙障,结合高立式和低立式红柳、芦苇生物沙障,不仅取得了阻沙、固沙、防止沙丘前移的理想效果,同时结合其他人工措施短时间内大幅度增加沙丘的植被盖度,达到了阻沙、固沙和增加植被盖度的双赢目的。

For controlling sandy damage in K90 - K100 along 207 national highway, the better way is to plant sand barrier on moving sand, and combine high type and short type plant sand barrier. In this way, an ideal effect should be obtained in sand fixation. Combined with other artificial measures, plantation coverage of dune can be increased in large scale.
