摘　　要：根据橘小实蝇的致死温度和有效积温,用Access设计气候资料和地理信息数据库,用MapX和Visual Basic设计程序,建立了橘小实蝇地理分布模型.用中国670个气象站点30a的气候资料运行该模型.结果表明,橘小实蝇可在中国25%的地区发生,分布北界为(30±2)N左右,1a发生3-12代.Based on the fatal temperature and effective accumulation temperature of or iental fruit fly, using Microsoft Access designing database, MapInfo MapX an d Microsoft Visual Basic designing program, the geographical distribution model of oriental fruit fly(GDMOFF) was established for studying its geographical dis tribution. GDMOFF was performed by 30-year climate data of 670 meteoroligical s tations in China. Result showed its potential distribution area accounted for a bout 25 percent of China, the border of northest distribution was about (30±2) N, it generated 3 -12 genera tions in one year.
