| 摘 要： | 从资源状况、土壤的理化性状、种群、群落、遗传多样性以及保护对策6个方面概述了国家二级重点保护植物——七子花的研究进展。七子花间断分布，分布范围小、数量少，并呈衰退的趋势，有灭绝的危险，其主要原因是遗传多样性较低、环境适合度差及人为破坏作用。最后提出七子花的几点保护对策。

| Abstract: | The latest development of researches on Heptacodium miconioides, the national second-ranking protection plant in China was summarized on the resources, soil physical and chemical properties, populations, communities, genetic diversity and protection strategy. Distribution of H. miconioides is discontinuous in small area, and with tendency of decline. Low level of genetic diversity, bad acceptance to environment and human activities were the major causes for its rare and endangered conditions, as the result, protection countermeasures were presented. |
