Abstract: Based on the requirements of growth and development of Brazilian upland ratooning rice(IAPAR-9) for the climate conditions and the experimental results of introduced rationing rice in Guangxi,the climate division indexes for planting of brazilian upland ratooning rice were determined.The spatial computative model for the climate division index was established by the methods of mathematics statistics.And the correlative values of climatic elements were worked out on small grid of l km x l km with GIS.By the function of spatial analyses and multi_overlapping method of GIS,Fitting region were partitioned for planting brazilian upland ratooning rice in Guangxi,The scientific basis with reasonable distribution of developing brazilian upland ratooning rice were provided in Guangxi according to the result.

Key words: GIS technology, GIS technology, Brazilian upland ratooning rice, Climatic division
