摘　　要：采用《IUCN物种红色名录濒危等级和标准(3.1版)》对广西原记录有野生稻分布的14个市59个县240个乡(镇)1100多个分布点进行实地调查和濒危现状评估。实地调查发现有58个县属濒危以上等级,表明广西野生稻自然资源濒危现状严重。指出广西野生稻自然资源濒危现状严重主要是由于原生地消失、原生地环境质量恶化、外来物种入侵、过度放牧与频繁刈割等原因造成。提出提高野生稻保护级别;加大宣传力度,提高对野生稻自然资源的保护意识;完善野生稻资源的保护法规;加强对生态环境的保护、建立完善的野生稻原生境保护体系等保护措施。According to the IUCN RED LIST Categories and Criteria （Version 3.1）, a field survey for recorded wild rice in Guangxi was conducted in more than 1100 localities in 240 townships/towns, 59 counties and 14 cities and their endangered situation was assessed. The survey results showed that out of 59 surveyed counties, 58 were in imminent danger or danger, and that indicated the endangered situation of wild rice resources in Guangxi was serious. The serious situation was caused by loss of in-situ sites, deterioration of ecological environment, invasion of foreign species, overgrazing and frequent cutting, etc. Therefore, several measures for protecting wild rice resources have been put forward including rising the protection level, increasing people＇s awareness for protecting wild rice resources, perfecting laws and regulations of wild rice resources protection, strengthening the natural eco-environment protection, setting up in-situ conservation sites, etc.
