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。
Based on the climate data and geographic information data of 18 meteorological stations in 18 cities of Hainan Province from January 1961 to January 2010, according to the temperature indices of fertility sensitive period and heading and flowering date of two-line hybrid rice, This paper will provide a scientific basis for providing reasonable planning, layout and sustainable development for the south part of two-line hybrid rice CMS line under the background of climate warming. The results showed that the suitable planting areas were mainly distributed in the areas of Wuzhishan, Jianfengling and Diaoluoshan. The sub-suitable areas extended northward to the middle of Wuzhishan and to the south of East, Changjiang, Qiongzhong and Wanning, and most of other cities and counties Not suitable for the area.
