摘要
葱属(Allium Linnaeus)植物是具有重要价值的植物资源。中国新疆地区位于亚欧大陆腹地,地处亚洲中部,且具有丰富的葱属植物多样性。查证葱属植物相关书著、文献资料及标本信息记录,探讨新疆葱属植物资源及其区系地理特征,为该属植物的系统分类、生物多样性保育以及资源合理开发利用等方面提供参考。依据已有的葱属相关记录和资料,新疆葱属植物有58种、1亚种、2变种、6栽培种。新疆分布的葱属植物的区系地理特征:(1)新疆葱属植物的分布地域主要集中在天山、伊犁塔城、阿勒泰、喀什地区,新疆葱属植物多生长于荒漠、草原、干旱坡地、砾石地、山地、高山、林下(森林)生境;(2)在地理成分的分布区类型中,新疆葱属植物主要分布在Ⅱ C5b准噶尔亚地区,Ⅱ C5b的区系属于温带荒漠性质;ⅠA2阿尔泰地区、ⅡC5a塔城伊犁亚地区、ⅠA3天山地区、ⅡC6c喀什亚地区也相对较多;(3)在新疆植被区划的系统单位类型中,新疆葱属植物分布在ⅠB1(阿尔泰山-北塔山草原省)、ⅡA2(东天山北坡草原云杉林及高山草甸植被省)、ⅡA1(准噶尔盆地半灌木荒漠植被省)、ⅡB3(天山南坡荒漠及山地草原植被省)植被省的种类较多,其次是ⅡB1(东疆砾质戈壁灌木荒漠植被省)、ⅠA1(准噶尔盆地西部山地草原省)、ⅡB2(塔里木盆地灌木荒漠植被省)植被省,分布在ⅡB4(帕米尔-昆仑-阿尔金山地荒漠与高山草原植被省)、ⅠC1(新疆南部高寒草原省)植被省的种类相对较少;(4)新疆葱属植物的水平分布和垂直分布均存在分异;(5)新疆葱属植物与哈萨克斯坦、俄罗斯的共有种较多,中国新疆地区与哈萨克斯坦、俄罗斯之间的葱属植物共有种数无太大差异且共有种的相似度较高。今后还应综合分子系统发育(植物系统发育区系地理学)、演化历史(历史植物地理学)、分子生物地理学等方面进行纵深�
The Allium Linnaeus is an important plant resource of great value with many species. It is situated in Central Asia and the hinterland of the Eurasian continent. Xinjiang of China harbors a wide plant diversity of Allium Linnaeus. To probe into the plant resources and the floristic characteristics of Allium Linnaeus in Xinjiang Province, combining and verifying monographs, literature, bibliographies with specimens from this genus can provide some profound support and outline for taxonomy, classification, biodiversity conservation as well as proper and sound utilization of Allium plants. We hope this study can help further research into this genus(Allium Linnaeus). Based on previous and present references, studies, records, and information about Allium Linnaeus,Allium plants from Xinjiang Province comprise about 58 species, 1 subspecies, 2 varieties, and 6 cultivated species. The floristic characteristics of Allium Linnaeus in Xinjiang Province are summarized as follows:(1)Allium plants of Xinjiang Province are mainly distributed in the Tianshan Mountains, Ili, Tacheng, Altay, and Kashgar, with most of them inhabiting the deserts, steppes, the dry slopes, gravel grounds, mountains, alps, and forest floor(or forests).(2) In terms of the areal-types of geographical elements, the Ⅱ C5b elements(the Junggar subregion, of the temperate desert) has the largest percentage composition, followed by the ⅠA2(the Altay region), ⅡC5a(the Tacheng-Ili subregion), ⅠA3(the Tianshan region), Ⅱ C6c(the Kashgar subregion).(3) From the perspective of the vegetation regionalization of Xinjiang, the Allium plant species in the vegetation provinces with the ⅠB1, ⅡA2, ⅡA1, ⅡB3 make up most vegetation regionalization types in Xinjiang;the ⅡB1, ⅠA1, ⅡB2 follow this;and with a relatively few occurrences in the vegetation province Ⅱ B4, ⅠC1.(4) Both horizontal distribution and vertical distribution of Allium Linnaeus in Xinjiang are differentiated.(5) The common Allium species in Xinjiang and the adjacent countries
