摘　　要：【目的】分析稻水象甲在全国的适生性和入侵广西水稻主产区的风险,为制定其防治措施提供参考依据。【方法】运用DK-GARP模型分析稻水象甲在全国的适生性,分析其在广西的扩散风险。【结果】目前,稻水象甲已蔓延到我国东北、西北、华北、华中、华东、西南等20个省(市),主要为近沿海城市和部分内陆城市;在广西周边省份如湖南、云南、贵州均已有该虫分布。预测结果表明,28个省(区)将成为稻水象甲的高风险区。随着中国与东盟国家的经济及国际贸易的发展,稻水象甲在广西扩散的途径和机会越来越多;此外,广西优越的地理和气候条件非常适合稻水象甲的生长繁殖。【建议】广西已成为稻水象甲扩散的高风险地区,必须提高警惕,加强检验检疫,从源头上堵截疫情,严防稻水象甲入侵。[Objective]The present study was conducted to analyze the adaptability in China and invasive risk of Lissorhoptrns oryzophilus Kusehel in Guangxi rice producing areas in order to provide references for its control. [ Method ]The distributing adaptability in China and risk analysis in Guangxi of L. oryzophilus was analyzed through DK- GARP model. [Result]The results showed that RWW was found to distribute in 20 cities and provinces of Northeast, Northwest, North China, Central China, East China, and Southwest China at present. The main distributing regions of RWW were nearer to the coastal cities and some inland provinces viz., Jilin, Liaoning, Zhejiang, Beijing, Tianjing and Hunan, which were fit for rice production. The neighbor provinces of Guangxi such as Hunan, Yunnan and Guizhou also appeared RWW. The 28 provinces （regions） in China were the high-risk regions of RWW invasion. With the rapid deve- lopment of economy and international trade and commerce between China and Association of Southeast Asian Nations, the spread paths and opportunity of RWW became mare and more. Furthermore, the advantageous geography and weather conditions of Guangxi are much fit for growth and reproduction of L. oryzophilus, Guangxi had become the high-risk spread area of L. oryzophilus. [ Conclusion ]Guangxi must be on the alert and strengthen inspection and quarantine of L. oryzophilus, and should cut off epidemic situation from source in order to prevent L. oryzophilus to invade Guangxi,
