摘要
沙坡头地区降水稀少,多年平均降水仅186.6mm,且分布不均。平均降水年变率为27％,易形成干旱。因此,在流沙固定中应加强机械固沙措施的研究和抗旱植物品种的培育和引进。
The Precipitation in Shapotou region is scarce and unevenly distributed, total annual precipitation being 186. 6mm. With a annual variation of precipitation of 27% this region is particularly easy to cause drought. Therefore,is should put stress on mechanical measures and introduce drought-resistant plant species in Sand dune stabilization.
