| 摘 要： | 濒危植物半日花为古地中海植物区系的残遗植物,现为亚洲中部荒漠的特有种,半日花对研究亚洲东部,特别是研究我国荒漠植物区系的起源以及与地中海植物区系的联系有重要的科学价值;对干旱草原和荒漠的防风、固沙来说是一种难得的优良物种;也是一种具有观赏价值的小灌木.半日花在我国可形成小面积的荒漠群落,由于过度放牧及乱挖烧柴,受到较严重的破坏,数量已逐渐减少,因此对其进行保护成为一项重要的研究课题.文章比较系统的概括了半日花的研究现状,同时对半日花濒危的原因进行分析,并提出保护对策,旨在为半日花的研究提供理论依据.

| Abstract: | The endangered plant,Helianthemum Songaricum Schrenk,is an old-relic species of tethys and mainly distributed in the eastern Asia.It is not only a rare species,but also a valuable resource for scientific research on the genesis for desert flora in China and the contacting with flora in tethys of plant distribution.It is also a good species for the use of windbreak and desert control in arid grassland and desert region.In China,Helianthemum Songaricum Schrenk should be grown as a kind of small desert community,but because of overgrazing and irrational firewood collecting,its community has been destroyed and its individual number has been reduced.Therefore,it is necessary to study how to protect Helianthemum Songaricum Schrenk and its community.Based on the progress of Helianthemum Songaricum Schrenk and the causes of its degradation,some conservation countermeasures for it are proposed. |
