摘　　要：半日花是半日花科的一种半灌木或灌木,稀为一年生或多年生草本孑遗植物。全世界约有8属200种,多分布于地中海沿岸。我国内蒙古、新疆有2种分布,分别是新疆半日花和内蒙半日花。由于自然因素和人类经济活动的影响,特别是采矿、烧柴、放牧、土地开发以及城市化,加剧了对半日花的过度开发,导致其生物量锐减,造成个体衰退,种群缩小的濒危状况,被国家列为二级保护植物。所以加强对珍稀濒危植物半日花的研究和保护具有重要意义。Common rock-rose Helianthemum soongoricum Schrenk and H. ordosicum Y. Z. Zhao, Z. Y. Zhu et R. Cao are usually bushes sparsely annual or perennial herbal relic plants. There are about 200 species in 8 genera that distributes along Mediterranean. Among them, 2 species distribute in Inner-Mongolia and Xinjiang Uigur autonomous region in China. Common rock-rose was listed a important protected plant by Chinese government due to that natural disaster, human activities and over-development have caused biomass reduce, population decrease and community downfall. It is a great importance to study and protect the rare and endangered plants common rock-rose Helianthemum soongoricum Schrenk and H. ordosicumY. Z. Zhao, Z. Y. Zhu et R. Cao in China.
