摘要
沙丘植物水分关系是确定毛乌素沙地流动沙丘适宜植被覆盖度的主要因子。根据植物耗水量的计算来确定适宜的植被盖度，其结果表明，臭柏的盖度为６７％～８５％，樟子松为６２％～８０％，旱柳为２７％～８０％，沙柳为４６％～７５％，杨柴为１４％～８０％，柠条为３１％～５０％，籽蒿为４６％～６５％，油蒿为３０％～７０％，植物最大盖度值常出现在沙丘丘脚或覆沙滩地。
The water relation of dune plant have been
considered as a mainfactor to decide the suitable cover degree of drift sand dune in the
MaowusuSandy Landin this paper.According to the water content consumed by
plant,thesuitable coverage have been calcuiated.As a result,the coverage of Sabina
vulg-arisshould be 67～85%,Pinus sylvestris var.mongolica 62～80%,Salix matsudana27～
80%,S.psammophyla 46～75%, Hedysarum fruticosum var.mongolicum14～80%, Caragana
intermedia 31～50%, Artemisia sphaerocephala 46～65%,A. ordosica 30～70%,The biggest
cover degree can be used in the foot of sanddune and the meadow covered with sand where
the water condition is goodenough.
