青海共和盆地高寒流动沙丘快速治理技术

研究了共和盆地流动沙丘的快速治理技术，结果表明：流动沙丘快速固定需要机械措施和生物措施相结合，机械沙障可在短期内将流动沙丘完全固定，但是，如果不采取生物措施，沙丘有可能在2～3年内复活，而生物措施固定流沙，初期效果缓慢，有时甚至难以实现。采用机械沙障将沙丘先加以固定，然后实施生物措施。这种生物与机械相结合的流动沙丘治理技术是类似共和盆地立地条件下治理流动沙丘的最佳模式。

Study on quick control technique of migratory dune in Gonghe basin of Qinghai

The quick control techniques of migratory dunes were studied in Gonghe basin sandy area.The results showed it needs combined with each other between machinery measures and biological measures for quick control of migratory dunes.Migratory dunes could be fixed wholly during short time.But it will be changed migratory dune during 2~3 years if no biological measures.The control sand effect was slowly at first time with biological measures.It is too difficult to realize sometimes.Migratory dune was fixed by san...
