两系杂交稻制种基地气象决策支持系统

制种基地和时段的选择是两系杂交稻制种成败的关键，根据历史气象资料和制种不同时段对气象条件的要求确定两系杂交稻种子生产的适宜气候区域与时段能够为两系杂交稻制种提供决策支持。运用可视化编程工具Visual Basic6．0，通过对气象站点的温度、降雨量、湿度等历年气象资料进行预处理，借助于XML进行合理的存储，将地理信息系统（Geographic Information System，GIS）集成二次开发的思想应用于可视化编程中，设计开发了两系杂交稻制种基地气象决策支持系统。利用湖南省50a的气象资料，依据该系统确定了湖南省两系杂交稻制种的适宜区域与时段。结果表明，决策系统运行结果与实际情况相符，系统具有较好的决策功能。该系统可为两系杂交稻的高产高效安全制种提供强有力的技术支撑。

Climate Decision Making Support System for Seed Production Bases of Two-Line Hybrid Rice

The selection of suitable sites and fight season is vital to the success of the seed production of the two-line hybrid rice. The suitable climate regions and periods for seed production were determined to provide the decision making support systems for the seed production, based on the historic climate data and the requirements for the meteorological conditions during the different periods of the seed production. The historic data of the temperature, precipitation and relative humidity were analyzed by using Visual Basic 6.0, and storaged by Extensible Markup Language （XML）, based on Geographic Information System （GIS）. The best region and season for seed production in Hunan was identified based on climate data for the last 50 years. The results obtained using this system matched well with the current identified season and location most suitable for seed production in Hunan Province. This decision making support system is very helpful in decision-making related to two-line hybrid seed production.
