| 摘 要： | 在呼伦贝尔沙地采用网格状生物活沙障直播技术具有明显的固沙效果。跟踪调查表明：直播3年植物盖度为55%,杨柴平均高度增加到78.3 cm,沙障网格中心平均风蚀下降到0.2 cm。并且随着沙障生长时间的延长,能够迅速形成不同类型的结皮,形成＂结皮肥岛效应＂。 |

| Abstract: | The effects of fixing sand with grid biological living sandy barrier by direct seeding are obvious in Hulunbeier Sandy Land. The investigation show that after direct seeding for 3 years, the vegetation coverage is 55 percent, the average height of Hedysarum fruticosum var. mongolicum Turcz has increased to 78.3 cm, and the average wind erosion in the middle of grid sandy barrier has decreased to 0. 2 cm. As the sandy barriers grow, different types of crust can be formed rapidly, and the effect of eurst fertile island can be formed. |
