Abstract: The higher plant floristic composition of Hebei Province including Sibirica and Eurasian temperate grassland elements and many species moved from north cold areas, elements expanded from tropic and subtropical zone of southwest China. All these elements meet here and make the flora of the Province take on a vivid transition. The geological history of Taihang and Yanshan Mountains are longinquity, the plant flora not only preserved some tertiary relic species but also brought many endemic species which only distribution in North China mountainous region. According to the study on the plants'geographic distribution, ecological environment, population and the actuality of the using of plant resource, the present paper analysed the geniue loss index and the urgent conservation value of vegetation, and gave a method to deter the conservation classes. Based on the criterion, the authors divided the 70 rare and endangered plants of the Province into three classes. The species number of the first class is 19, the second class is 22 and the third class is 29 species. Therefore, aside from analysis of reasons in rare and endangered plants in Hebei Province, some strategies for protection are put forward.
