中文摘要	豆科锦鸡儿属约80种,可以明确地分为6组14系.编绘了79个种的分布图,在此基础上,描述了每个种的分布范围和生存生境,以系和组为单位探讨了锦鸡儿属植物各类群的分布规律,并进一步研究了种类形成和演化过程.Sect.Caragana为东亚--蒙古高原分布型,其Ser.Caraganae的种类在东亚地区随纬度的变化呈现出明显的地理替代分布规律,Ser.Microphyllae在蒙古高原地区随经度的干旱梯度变化呈现出清晰的种类替代关系,本组各系间也有明显的地理替代分布现象.Sect.Prunosa为东亚--中亚间断分布型.Sect.Longispina为喜马拉雅分布型.Sect.Tragacanthoides为环青藏高原--北极高山分布型.Sect.Frutescentes广泛分布于亚洲干旱地区.Sect.Chamlagu为东亚分布型.本属种类可分为6个分布型,分布型之间的关系揭示了亚洲干旱区植物区系形成的渊源和联系.Sect.Caragana为本属的原始类群,起源于东亚,曾广泛分布于亚洲大陆,随青藏高原的隆起,原始类群就地分化形成不同的类群,在此基础上迁移分化适应,形成了现代多样的分布格局,中亚为本属的分化中心.
英文摘要	The distribution map of each species is given ( partialy compiled). According to that, geo-graphical ilislribulion of the genus Caragana Fabr. are systematically studied. Firstly, classification, e-volulion system of ihe genus are discussed. It can be summarized follows: Classification system; There are about 80 species in the genus belonging to 14 series, 6 section. Phytogeographical distribution; Firstly, the geographical distribution map of each species are given, basing that, distribution pattern of each species in each series and that of each series in each section are discussed. Then, distribution characteristics of the genus, Asia-temperature zone distribution, two center of abundance, expansion in west-east direction (latilude) and decline in north-south direction (longitude) are resulted. Origin, dif-ferentiation, migration: Series Caraganae is original type which take place (originated) from East-Asia in early-middle period of Territory period. The original type migrated rapidly in large scale, and formed the background of the genus evolution. Because of the change of climate and habit by Tibet plateau lift-ing, variety group was selected out in different place. New taxon units were produced in place with con-slant changing of climate and habit. In addition, relationship between morphological characteristics and climate as well as habit arc studied.
