摘　　要：应用除趋势对应分析和系统聚类分析对中国境内十大功劳属(Mahonia)和淫羊藿属(Epimedium)植物的分布式样进行了统计分析.结果表明:中国境内十大功劳属植物可分为西南-华中区、华南区、华东-华中区和热带区,以中国特有成分为主,其次为东亚成分和热带亚洲成分,分别占中国十大功劳属植物总数的90.63%、3.13%和6.25%;四川、云南、广西是中国十大功劳属植物资源最丰富的地区.中国的淫羊藿属植物可以分为西南-华中区、北方区、华东区、东北区和东南区,除朝鲜淫羊藿(E. koreanum)呈现东亚分布式样外,其余均为中国特有种;四川、湖北、贵州是中国淫羊藿属植物的多样性中心.The distributive patterns of Chinese Mahonia and Epirnedium were studied by Detrended Correspondence Analysis （ DCA ） and System Cluster Analysis. The results were summarized as follows ： The geographic distribution of Chinese Mahonia could be divided into five regions including South-western China area, Southern China area, Eastern Central China area, and Tropical area; The geographic elements of Chinese Mahonia include the element endemic to China, Eastern Asian element and Tropical Asian element, accounting for 90.63%, 3.13% and 6.25% of the total species of the genera in China respectively; Most species of the genera have been recorded in Sichuan, Yunnan, Guangxi. The geographic distribution of Chinese Epimedium could be divided into four regions including Central China area, South-western-central China area, Northern area, Eastern China area, Northern-Eastern China area, Southeastern China area; All the species of Chinese Epimedium are endemic to China except E. koreanum, the latter shows Eastern-Asia distributive pattern. Sichuan, Hubei and Guizhou are the diversity center for Chinese Epimedium.
