摘　　要：【目的】调查广西野生秋海棠属植物资源,为其种质资源保护和开发利用提供参考依据。【方法】采用野外调查和文献资料查询相结合的方法,对分布于广西的野生秋海棠属植物资源现状、观赏价值与园林应用等进行调查与分析。【结果】广西野生秋海棠属植物资源共有83种(含变种),其中广西特有种44种,占所拥有总种数的53.0%,特有现象非常突出;野生秋海棠属植物在广西全境均有分布,但各地种类分布很不均衡;很多种类观赏价值高,在园林上具有多种应用方式,值得开发利用。【建议】加强对广西野生秋海棠属植物的科普宣传及其生长环境的保护,建立该属植物种质资源圃;开展引种驯化并加快观赏品质良种选育工作,研发具有国际市场竞争力的特色秋海棠新品种;加强在园林上示范推广,使资源得到可持续利用。[Objective ]The plant resources of wild Begonia in Guangxi were investigated to provide scientific refer- ences for their protection and utilization. [ Method ] Using the method of field investigation and data query, the resources status, ornamental value and landscape application of wild Begonia in Guangxi were surveyed and analyzed. [ Result] The results showed that there were 83 species and varieties, of which 44 species were endemic to Guangxi, accounting for 53.0% of the total species. Unique phenomenon was very prominent. Wild Begonia distributed unevenly in the province. Many species had high ornamental value and many application ways, which meant they should be developed and utilized. [Suggestion lit should be strengthened to promote scientific publicity and conserve natural habitats of Be- gonia resources. It is urgent and necessary to establish the plant nursery of germplasm resources, introduce more vari- eties and acclimatization, accelerate the breeding of improved variety of ornamental quality and exploit new varieties with Guangxi characteristics which possess competitiveness in the international market. The new varieties should be demonstrated and extended to achieve sustainable utilization of Begonia resources.
