山蒿生物学特征及其生态保护应用价值潜力初探

Preliminary study on biological features of Artemisia brachyloba Franch. and its application potential in ecological conservation

基于野外科学调查中发现且有应用于水土保持生态修复等领域潜力的次生植物——山蒿,通过设置室内实验研究了其种子和幼苗期生物学和生态学基本特征;结合野外成苗观测,探讨其水土保持和生态保护价值问题。初步认为:(1)山蒿植物有进一步深入研究和进行系统保护的必要性;(2)针对本研究发现山蒿应用的局限性,育苗期水肥的精准管理可能是改进苗期生长缓慢的关键措施;(3)利用遥感和地面调查等手段,山蒿的资源集中分布区域识别和生态保护规划应是目前紧迫的任务。基于其生态保护价值与资源开发利用潜力,期望更多的学者给予关注和讨论。

Artemisia brachyloba Franch.is a kind of secondary plant in arid and semi-arid region of northern China.The authors think that it have applied value in the field of soil and water conservation and ecological restoration,which was discovered during field investigations.The basic biological and ecological features of Artemisia annua Franch.were studied in laboratory,and its value of ecological conservation was discussed in combination with field observation.The preliminary conclusions are that(1)it is necessary for Artemisia annua Franch.to be further researched and systematically protected,and(2)there are some limitations of its application according to current research results,and precision management of water and fertilizers is probably improvement measures during seedling period,and(3)resource distribution of Artemisia annua Franch.surveys and ecological conservation planning using remote Sensing observation and field investigation may be urgent tasks.
