摘　　要：根据沙田柚对气候条件的要求,分析确定了沙田柚种植的农业气候区划指标。利用广西90个气象台站30年的气候资料和1∶25万基础地理数据,建立区划指标的空间分析模型,按1km×1km细网格推算出无测站地区区划指标的空间分布。运用GIS技术划分出广西沙田柚种植的最适宜、适宜、次适宜和不适宜区,针对各区域气候特点提出了相应的建议,为沙田柚的合理布局以及趋利避害提高沙田柚产量和品质提供科学依据。According to the requirement of Shatian pomelo cuhivar to climatic conditions, and based on the analysis of the climatic data of 90 weather stations accumulated in 30 years and the fundamental geographic data on the scale of 1 to 250 000 in Guangxi, the optimal, fitting, sub fitting and unfitting districts for growing Shatian pomelo cultivar are regionalized. Due to using GIS technology such regionalism will guarantee the success of growing Shatian pomelo in each district and decreasing the disaster caused by the disadvantage climatic factors.
