浅谈双行沙障防风固沙技术

On the technology of double-row sand barrier for wind-proof and sand-fixing

承德沿坝沙化区是河北省生态环境建设的重点地区,该区风蚀沙化、水土流失严重,造林树种单一、成活率低,地表植被脆弱,植物群落发展极不平衡,生态环境日趋恶化。使用双行沙障技术,前期阻住了风沙,后期死体沙障腐烂成为有机质,为活体沙障提供了养分和水分,极大提升了活体阻沙能力,为快速恢复植被,提高苗木保存率,奠定了坚实基础。

The desertification area of yanba in chengde is the key area of ecological environment construction in hebei province, which is characterized by severe wind erosion, sand erosion and soil and water loss, single afforestation tree species, low survival rate, fragile surface vegetation, unbalanced development of plant community, and deteriorating ecological environment. The double-line sand barrier technology can prevent the wind from blowing sand in the early stage, while the dead sand barrier decays into organic matter in the late stage, which provides nutrients and water for the living sand barrier, greatly improves the living sand barrier’s ability, and lays a solid foundation for the rapid restoration of vegetation and the improvement of seedling preservation rate.
