摘　　要：通过区系组成和地理成份的对比分析，对德夯风景区及其邻近的8个区系进行比较研究，结果表明德夯与这8个区系间存在着程度不一的区系联系。相对而言，德夯与梵净山、佼母溪和壶瓶山的关系更为密切，区系同质性最高，表明它们共属华中地区武陵山─—巫山亚区这一整体，德夯则刚好处于这一亚区整体的南缘而与雷公山─—雪峰山亚区相衔接。Based on comparative analysis of flo1istic compositions and geograhical elements of Dehang and its 8 neighbour flora, the results show that there are close relationships which Dehang and jts 8 neighbour flora in a fairly high level. Compared with other regions, Dehang is much more closely allied to Fanjingshan, Jiaomoqi and Hupinshan mountain. They are a whole, namely Wuling and Wushan mountain subregion of Central China region, Dehang is located right in the south boundary of the whole linking with subregion of Xuefeng shan and Leigongshan.
