摘  要:
降水量小而蒸发量大是造成毛乌素沙地干旱缺水的首要原因,风多风大及光照强烈加剧了土体和植物水分的散失,因此导致植物群落衰退或个体死亡。为了提高造林效果,必须根据沙地生境的异质性科学构建森林生态系统、积极推广应用抗旱节水措施、合理利用克隆植物的优越性。

摘  要:
The chief cause of the water shortage in the Mu Us sandland is that the less precipitations but more evaporation,windy strong wind and extreme illumination made soil mass and plant water to evaporate quickly,therefore lead to the recession of plant community or the death of individual.In order to enhance the effect of planting,we must construct forest ecological system、actively promote the application of drought-resistant and water-saving measures and use the superiority of clonal plants reasonably according to the heterogeneity of sand habitat.
