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.
