The three safe periods that we should pay attention to are put forward. Using spatial analysis of GIS, the climate risk for seed production is assessed on the basis of Hunan climate data in 50 years and analysis on the relationship between climate fac- tors and the longitude, latitude, height above sea level. The climate decision-making support sys- tem for seed production base area of two-line hybrid rice is designed and appropriate region and season for seed production are decided. The system provides the technical support for the site se- lection of the two line hybrid rice seed production.
