摘　　要：根据气候和地形等因子,采用专家分类器方法对北京市的京白梨种植区进行了农业气候区划。结果表明:平谷、密云、怀柔、昌平、门头沟和房山的浅山区为京白梨的适宜种植区。与其他的区划方法相比,专家分类器方法在农业气候区划中具有较突出的先进性和实用性,它能充分地将专家的知识、经验和科研成果应用到农业气候区划中,从而得到较客观和全面的区划结果。Based on the climatic and topographic factors, an expert classifier is used to make an agroclimatic regionalization of Beijing Pear. The results indicate that the optimum planting areas of Beijing pear are around the retuse hills near Pinggu, Miyun, Huairou, Changping, Mengtougou and Fangshan. Compared with other classitiers, the expert classifier has significant advantage and practicability in agroclimatic regionalization, since it makes full use of the experts＇ knowledge, experiences and the scientific researches in achieving an objective and comprehensive regionalization.
