摘要
根据巴西陆稻IAPAR-9生长发育对气候条件的要求,结合其在广西的引种试验结果,分析确定了广西种植巴西陆稻再生稻的气候区划指标;利用数理统计分析方法,建立气候区划指标的空间推算模型,并采用GIS技术推算出广西lkm×lkm网格点上的有关气候要素值,利用GIS的空间分析和多层复合方法,对广西的巴西陆稻再生稻进行气候区划,为广西巴西陆稻再生稻的合理布局提供科学依据。
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 1 km × 1 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.
