中文摘要	半日花(Helianthemum songaricum)为亚洲中部特有种和古地中海残遗植物,其群落为内蒙古西鄂尔多斯地区的特有荒漠植物群落。该文以2016-2017年野外调查数据为基础,结合相关文献资料,对半日花荒漠群落的分布、群落特征及其分类进行了总结。结果表明:(1)半日花荒漠群落集中分布于黄河以东内蒙古西鄂尔多斯的阿尔巴斯山麓南北部、千里沟;少量分布于黄河以西贺兰山北端内蒙古乌海市与阿拉善盟交界处及贺兰山最南端的内蒙古阿拉善盟与宁夏交界处明长城沿线的石质残丘。(2)根据样地调查,半日花荒漠群落记录到种子植物58种,隶属于17科39属,其中灌木、半灌木18种,多年生草本27种,一年生草本植物13种;水分生态类型中强旱生植物(15种)和旱生植物(29种)占绝对优势;区系地理成分以中亚东部成分为主,其次为古地中海成分和戈壁成分。(3)根据生活型和优势度,半日花荒漠群落可分为半日花-草本荒漠群丛组、半日花-灌木-草本荒漠群丛组和半日花-半灌木荒漠群丛组,进一步分为10个群丛。
英文摘要	Aims Helianthemum songaricum is an ancient Mediterranean remnant plant species endemic to central Asia,and it is a dominant species of a unique desert community in west Erdos,Nei Mongol,China.We studied the distributions,classification and characteristics of the H.songaricum communities.Methods We collected species composition for 18 plots from literatures and field investigation during the growing seasons of 2016 and 2017.We then applied TWINSPAN to classify community types.Important findings (1) The H.songaricum communities were primarily distributed in the north and south of the Arbas Mountains and Qianli Ravine in west Erdos,with some in the southern and northern Helan Mountain.(2) In total,58 seed plant species belonging to 39 genera from 17 families were recorded,including 18 shrub and subshrub,27 perennial and 13 annual herbaceous species.Super-xerophytes and xerophytes were the two major ecological types,accounting for 26% and 50%,respectively.The Central Asia-Eastern Asia was the major floristic elements,followed by the Palaeo-Mediterranean and the Gobi elements.(3) Based on the life forms and species composition,the H.songaricum communities was divided into three major association groups,i.e.,H.songaricum-herbs desert group,H.songaricum-shrubs-herbs desert group and H.songaricum-subshrub desert group,which were further divided into 10 associations.
