Characteristic and Construction of Vegetation in Maowusu Sandy Land
, 2005 毛乌素沙地的高等植物共有1 106种,分属于98科420属。主要的科有菊科、禾本科、豆科、蔷薇科、藜科。主要的属有蒿属、黄芪属、葱属、柳属、杨属,主要的种有沙蒿、沙竹、牛心朴子、沙柳、乌柳。植物群落类型有草原植被、草原和荒漠灌丛、沙生植被、草甸植被、盐生植被、沼泽和沼泽性植被、水生植被,其中沙生植被占主导地位,其次为草甸植被。植物群落主要有沙蒿群落、沙蒿—柠条群落和沙柳、乌柳、沙棘组成的“柳湾”。简述了毛乌素沙地的植被分布特征,提出该区植被建设应以灌木为主,采取灌、乔、

, 2009 通过野外采样和室内分析相结合,掌握了陕北毛乌素沙地不同采样点生物结皮层的理化性质以及该地区生物结皮的发育特征,为以后进一步研究毛乌素沙地生物结皮的防风固沙效应奠定了理论基础。结果表明:随着生物结皮的发育,结皮层厚度增加,最大值为11.82mm;土壤颗粒细化,0.02～0.05mm之间的颗粒含量为7.3%～27.7%,高于流沙中的颗粒含量;由于颗粒的细化,结皮层容重增加,其抗剪强度明显提高,且抗剪强度与厚度和容重之间存在一定的相关性。生物结皮层pH值为7.23～7.81,低于流动沙地的pH值;有机质 ...
