【摘要】 中国境内的帕米尔高原位于我国新疆西南部,是天山、昆仑山、喀喇昆仑山和兴都库什山等交汇而成的大山结,地处偏远,自然环境恶劣。本文对该地区的豆科植物进行了比较系统的形态分类学研究,并对其物种多样性、植物区系等进行了分析,对其资源利用做了初步评价。研究表明: 1.中国帕米尔高原豆科植物共有14属74种,分别占新疆豆科总属数的29.8%,总种数的18.5%。中国帕米尔新记录2属9种,其中新疆新记录6种。比已有文献资料新增2属9种。 2.中国帕米尔高原豆科植物属的分布区类型为7个分布型和3个变型,以温带区系成分为主,占豆科总属数的50.02%;缺乏热带分布型及中国特有分布型。 3.在中国帕米尔高原豆科植物中,多种属2属51种,为黄芪属和棘豆属,占其总属数的14.3%,总种数的68.9%;寡种属6属17种,单种属6属6种,中小属比较丰富,大属较少但包含种类较多。其中,中国帕米尔特有分布种7种,中国新疆特有分布种23种,新疆特有种2种。 4.中国帕米尔高原豆科植物生活型以地面芽植物为主,高达73%,多年生草本占主导地位,而高位芽、地上芽和一年生植物较少;生态型以中生植物为主,旱生植物较少,湿生和水生植物几乎没有。 5.该区域豆科植物资源比较丰富,有多种植物在食用、饲用、药用及观赏等方面具有重要的利用价信。更多还原

【Abstract】 The China Pamirs plateau located in the southwest of Xinjiang is a mountain joint formed by Tianshan Mountain, Kunlun Mountain, Kelakunlun Mountain and XingDuku Mountain. It’ s position is remote and natural environment is bad.This article has conducted the comparison system shape taxonomy research to this local Leguminous plant, and has carried on the analysis to its species diversity, the flora and so on, has made the preliminary appraisal to its resources use. The research indicated that:Ⅰ .In the Pamirs of China Leguminosae plant altogether has 14G 74Sp, accounts for 29.8% and 18.5% oftotal genera and species of Xinjiang Leguminosae. The Chinese Pamir new record is 2 G 9 Sp, Xinjiang new record is 6 species. It increases 2 G 9 Sp compared to old literature materials.Ⅱ .In the Pamirs of China Leguminosae plant areal-types are distributed to 7 areal-types and 3 subtypes. The temperate is dominating ingredient, account for 50.02% of all Leguminosae, without the tropics distribution and the Chinese unique distribution.Ⅲ.There are 2 multiplicate genus 51 species, accounts for 14.3% and 68.9% of total genera and species of Leguminosae plant in the Pamirs of China which are Astragalus L. and Oxytropis DC.It has 6 widowed 17 species and 6 autogenus 6 species. Among them, the Chinese Pamir unique distribution plants is 7 kinds, the Chinese Xinjiang unique distribution plants is 23 kinds, the Xinjiang endemic species is 2 kinds.Ⅳ .In the Pamirs of China of Leguminosae plant life forms, hemicryptophyte plant is dominant as high as 73%. The perennial herb occupies the dominant position.But phanerophyte, chamaephytes and therophyte are few. The ecotype is primarily the mesophyte, the xerophyte are few, the humidogene and the aquatic plant do not have nearly.Ⅴ .This region Leguminosae plant resources are quite rich.Many kinds of Leguminosae plants have the important value for edible, raiseing, medicinal purposes and watching aspects and so on.更多还原
