摘要
植物固沙是整治沙漠和沙漠化土地的一种有效措施。人工植被的建立是植物固沙的必然结果。人工植被的演替、稳定性及其对环境的影响直接关系到流沙的固定程度。因此,本文旨在探讨人工樟子松(Pinus sylvestris var.
The researches indicate that Artemisia halodendron grows rapidly at the initial stage of artificial vegetation establishment, with the largest rate at the second year and maximum coverage at the third year. After 15 years, it is replaced by successional plants such as Cleistogenes squarrosa etc.. At the meanwhile, seedlings of Pinus sylvestris var. mongolica grow up between stripes and form a relatively completely structured artificial vegetation ecosystem. Sand dunes are completely stabilized at the second to third year of vegetation establishment when the optimum wind-sheltering effect of Artemisia halodendron brings into play.
