摘 要 ：为了加强海南岛野生稻资源的保护和研究利用，2002年至2013年对海南省18市（县）野生稻资源进行野外调查、资源收集和原、异位保护。初步查明，目前在全省15个市县发现154个野生稻自然居群，其中普通野生稻136个、疣粒野生稻11个、药用野生稻7个。收集到野生稻居群87个，其中普通野生稻80个、疣粒野生稻4个、药用野生稻3个，总共2900余份野生稻种茎，经繁殖和编目后妥善保存于海南省农业科学院试验基地的热带野生稻异位保存圃中，并参照农业行业标准-农业野生植物原生境保护点建设技术规范，分别在文昌、琼海、儋州、万宁、陵水和保亭等县（市）建立了6个野生稻原生境保护点，其中普通野生稻4个，疣粒野生稻1个，药用野生稻1个。根据调查结果，对海南野生稻濒危状况及其根源进行了分析，提出了海南野生稻保护相关建议。

Abstract:To better conserve and utilize wild rice in Hainan, a survey on wild rice resources was conducted in 18 counties in Hainan from 2002 to 2013.As a initial investigation，154 natural populations, which included 136 populations of Oryza rufipogon Griff., 7 populations of Oryza officinalis Wall. and 11 populations of Oryza meyeriana Baill. , were found in 15 counties in Hainan. During the survey, total 2900 accessions from 87 natural populations were collected and conserved ex-situ in the temporary field genebank for tropic wild rice established in the research base of Hainan Academy of Agricultural Science. Meanwhile, 6 in-situ conservation areas of wild rice, which contained 4 Oryza rufipogon Griff., 1 Oryza officinalis Wall. and 1 Oryza meyeriana Baill., were set up in Wenchang, Qionghai, Danzhou, Wanning, Lingshui, Baoting respectively in accordance with the guidelines of procedure and methods of in-situ conservation of relatives of crops issued by the Ministry of Agriculture. Besides, this paper analyzed the endangering status and the root causes of wild rice in Hainan, and provided suggestions for the conservation strategies of wild rice in Hainan.
