中国鸭绿江流域种子植物区系研究

通过对中国鸭绿江流域进行实地野外调查和对以往在该地区采集的标本进行分类学鉴定，确定本地区种子植物112科498属1 230种.对这一地区的种子植物从属、种两级进行统计分析，结果表明:该区系属温带性质，特有现象明显，地理联系广泛.该区系以东亚地区特别是与日本相关的一些成分为主体，还有相当数量的北半球温带成分和少量寒带性质的成分.针对物种保护的现状，提出了中国鸭绿江流域珍稀濒危植物保护对策. 

Floristic study of seed plants in the Valley of Yalu River, China

Based on the field survey and identification of the specimens collected previously, 1 230 species, 498 genera and 112 families were recognized and reported in the Valley of Yalu River of China at the present study. The results of floristic analysis based on genera and species of the seed plants indicate that flora in the Valley belongs to the temperate zone in nature, and it is also evident in endemism. It has the wide connection with different regions in the world. And also, it basically consists of eastern Asian elements (especially closely related to Japan) that are dominant, some north temperate elements, few frigid zone elements. According to the present situation of plant conservation in the Valley of Yalu River, the effective measures for the protection of rare and endangered plants were also put forward.
