摘要： 为减少福建龙眼在低温冻害中的损失，实现科学合理的种植布局，进行本研究。根据龙眼的生长情况、受害程度与年度极端最低气温、种植区域的坡向、坡度的关系，确定龙眼冻害等级指标。利用福建68个气象台站的地理信息资料，建立龙眼冻害指标的空间分布特征模型，通过GIS技术推算出50m×50m分辨率的冻害指标空间分布。利用GIS的空间分析能力，得出福建龙眼低温冻害的分布规律。

Abstract: A study about scientific planting of Longan in Fujian was conducted in order to reduce its freezing damage. First, indexes about the freezing grade of Longan were identified according to the relationships among Longan growth, damage degree, annual minimum temperature, and the aspect and slope of planting region. Using the geographical information data of 68 meteorological stations, spatial distribution model of freezing damage indexes of Longan was established, and the 50m×50m resolution spatial distributions were simulated by GIS. Therefore, distribution rules of Longan in Fujian were analyzed by using GIS spatial analysis.
