锦鸡儿属地理分布式样的研究

Based on the phylogeny in Caragana Fabr., the distribution pattern of the genus were studied mainly by using the Subtree-TASS analysis, Acenstral Area Analysis (AAA), Dispersal-Vicariance analysis (DIVA), and Parsimony Anlysis of Endemicity (PAE). The results renewed some view of the origin, differentiation and evolution ad hoc L. Komarov floristic migration, and explained the congruence among ecological adaptation, phylogeny and distribution pattern. And the karyotype, DNA ITS and Trn sequences were obtained to be the evidences of the phylogeny and phylogeography.

对锦鸡儿属分类、分布等资料用DELTA系统作微机规范化处理。结合种系发生关系、DNA证据和有关分布区地史背景资料，应用分析生物地理学理论方法研究属的地理分布式样，对柯玛洛夫关于中国蒙古植物区系迁移说等观点再讨论再认识，并提出新见解。本项目作为该属分类学地理学深化研究，对于温带植物区系等地理及生物地理学新理论方法研究都有重要意义。
