Abstract将沙坡头地区优势藻种分离、纯化、批量培养;返接回当地流沙(棚内和棚外);入现场沙风洞实验室吹试;量化测定了藻种对风沙土的固定能力;筛选出适合当地生长的最好固沙藻种和藻种组合。并从藻类生物量、种类、群落组成、生物活性、藻结皮厚度、逆境锻炼;尘埃(包括尘埃的有无;量的大小;加入方式)及其它隐花植物等方面研究了它们对藻结皮强度的影响。结果表明具鞘微鞘藻和纤细席藻固定能力最强;具鞘微鞘藻占80%以上的搭配是较好的组合;结皮的零界风速量由于藻种的生长而明显提高;并且以丝状蓝藻最显著;叶状体次之;单细胞种类最差;薄结皮较厚结皮强度差;但藻类生物量的作用较厚度更为有效;少量多次加入的尘埃明显提高结皮强度;在藻结皮的早期形成过程中;藻类无可替代的起着最重要的最用;从而为微藻固沙技术提供了直接的可行性依据。
