| 摘 要： | 长青自然保护区内种子植物资源丰富多样,仅中国特有植物就有30属,占全国特有属总属数的11．67％,占长青自然保护区种子植物总属数的4.12％,隶属于26科．其中单种属17个,少种属12个,两者共占保护区的特有属总属数的96．67％,多种属1个．保护区内的特有植物以温带性质为主,并且具有明显的古老性．特有植物与毗邻省区有广泛的联系,特别是与四川、湖北、陕西化龙山的联系最为密切,共有的特有植物比例高．同时也表现出与整个秦岭地区植物区系较为密切的关系．因此,长青自然保护区不仅在地理位置上,而且在特有植物成分组成上与“川东—鄂西中国特有植物分布中心”存在十分密切的联系．

| Abstract: | There are 30 genera endemic genera of Chinese seed plants inChangqin natural reserve, which occuptied 11. 67% of total endemic gener ofChina and 4. 12% of all seed plants generain Changqin natural reserve. Theybelong to 26 families and include 17 single species genera, 12 few species generaand one many species genera. These endemic genera show obvious temperatanature and ancient origin character. They have an extensive relationships withthe adjacent rSgions, especially with Sichuan, Hubei province and Hualongmountain area of Shaanxi province as well as Qinling mountain area flora. So,Changqin natural reserve have relations with"East Sichuan-west Hubei distribution centre of the endemic plants of China"not only in the geographical position but also in the composition of the endemic plants. |
