摘要: 对神农架国家级自然保护区毛茛科植物进行区系分析研究，结果表明：该地区毛茛科植物种类异常丰富，共计19属97种；分布类型以温带分布区为主，属的温带分布区类型占81.25%；该地区区系成份丰富多彩，不仅是连接南北植物区系的纽带，而且还是中国-日本植物区系和中国-喜玛拉雅区系的交汇点.UPGMA聚类结果表明：神农架毛茛科植物区系成份与我国西南山区最为接近，其次与华中地区，东北，日本等地区也有较高的相关性.Abstract: A study on Ranunculaceae plants flora of Shen Nongjia National Nature Reserve was undertaken. The result shows that there are a great variety of Ranunculaceae plants whose total number of genus of Ranunculaceae plants is 19 and species is 97. Most of the plants are temperate types. The percentage of generic types of temperate floristic regions is 81.25%. The composition of flora in this region is rich and varied, which is the joint not only of the south and the north flora, but also of the Chinese-Japanese and the Chinese-Himalayas flora. Based on the result of UPGMA, the composition of Ranunculaceae flora of Shen Nongjia is mostly similar to that in mountain area of southwest China and has high relativity with those in the area of central China, northeast China and Japan.
