摘　　要：开展南繁秋季杂交水稻制种气象灾害风险区划对降低制种农户生产风险、拓展南繁杂交水稻制种季节具有重要意义。利用海南岛国家和区域气象站1971-2020年气象资料及2011-2017年南繁秋季杂交水稻制种生产气象灾害和产量等信息,采用杂交水稻制种的气象灾害指标,构建灾害风险强度指数模型并对种植区进行了风险区划。结果表明,南繁秋季杂交水稻制种气象灾害低风险区主要分布在三亚、陵水、乐东西部、东方西部等地区,高风险区主要分布在海南岛中部、东部等地区。南繁秋季杂交水稻制种低风险区宜安排在10月下旬始穗,南部可适当延后到10月底11月初始穗。It is of great significance to carry out the meteorological disaster risk zoning in autumn hybrid rice seed production of Hainan national breeding and multiplication to reduce the production risk of seed producers and expand hybrid rice seed production season of Hainan national breeding and multiplication.Based on the meteorological data from national and regional meteorological stations in Hainan Island from 1971 to 2020 and the meteorological disaster and yield information of hybrid rice seed production in autumn from 2011 to 2017,the meteorological disaster indicators of hybrid rice seed production were used to establish a disaster risk intensity index model and the risk zoning of planting areas was carried out.The results showed that the low-risk areas of meteorological disasters in autumn hybrid rice seed production of Hainan national breeding and multiplication were mainly distributed in Sanya,Lingshui,west Ledong,west Dongfang,etc.,and the high-risk areas were mainly distributed in the central and eastern regions of Hainan Island.The initial heading date for autumn hybrid rice seed production in the low-risk areas of Hainan national breeding and multiplication should be arranged in late October,while it can be appropriately delayed to the end of October and early November in the south of Hainan.
