摘　　要：利用海南18市县气象站1961—2010年1—3月气候资料和地理信息数据,根据两系杂交水稻不育系育性敏感期和抽穗扬花期的温度指标,应用GIS插值技术,采用综合评判的方法制作两系杂交稻不育系南繁精细化气候适宜性区划图,以期为气候变暖背景下两系杂交水稻不育系南繁提供合理规划布局和可持续发展提供科学依据。结果表明:适宜种植区主要分布在五指山、尖峰岭和吊罗山以南区域,次适宜区向北扩展到五指山市中部以及东方、昌江、琼中和万宁的南部,其它大部分市县区域为不适宜区。To provide reasonable layout and scientific basis for sustainable development of thermo-sensitivegenetic male sterility（TGMS） rice in Hainan Island under the background of global warming, this study basedon the meteorological data of January- March（1961- 2010） accumulated by 18 stations, geographicalinformation, TGMS rice fertility sensitive stage and heading-flowering stage desired temperature indicator,using GIS technology to built TGMS rice suitability zoning. The results showed that the suitable planting zonewas the south of Wuzhishan, Jianfengling and DiaoluoshanMountain field, Sub suitable zones mainly locatedinthesoutheastern and southwestern area,most areawasunsuitableregion.
