摘要
古尔班通古特沙漠中大规模、高强度的人类活动严重干扰和损坏了荒漠植被。在该沙漠特有的生境下 ,受损植被具有一定的自然恢复和更新能力。但要加速恢复过程 ,则需辅以积极有效的措施。本文经过跟踪监测人工种植荒漠植物的出苗、生长以及风沙土水分垂直分布特征 ,查明了植物出苗、存活率和风沙土中水分垂直分布的动态关系。
In Gurbantunggut Desert,human activities of large-scale and high strength have severely disturbed and damaged the desert vegetation.Under the peculiar eco-environment the damaged vegetation has a natural capacity of recovery and regeneration.However,to speed the process of vegetation recovery,active and efficient assistant measurements were necessary.In this work,through seeding Haloxylon ammodendron and Haloxylon persicum ,and monitoring plant's germination,survival and the characteristics of vertical distribution of the aeolian sandy soil moisture,the dynamical relationship between the germination and survival rates of plants and vertical distribution of the aeolian sandy soil moisture were pointed out.
