摘　　要：为了给陕西砂梨发展提供气候适应性地域分布依据,应用1971~2000年陕西省及相邻省份的114个气象观测站及其附近200个气象哨的气象观测数据,分析了光、热、水等气象条件对砂梨生长的影响情况,确定了气候区划指标,然后利用GIS技术对陕西省砂梨种植适生区进行了精细化的气候区划。结果表明：陕南的安康、汉中海拔小于600 m的盆地为陕西省砂梨适宜种植区,而陕西的其余大部分地区,因气温偏低、降水不足,不利于优质砂梨的生长,故不宜盲目引种砂梨。In order to provide regional distribution basis of climatic adaptability for development of sand pear,effects of the weather conditions,light,heat and water,on growth of sand pear were analyzed,and the indicators of climatic regionalization were determine,based on the meteorological observation data（1971-2000） from 114 meteorological observation stations and vicinal 200 meteorological posts in Shanxi and its neighboring provinces.A meticulous climate division result of sand pear suitable distribution area in Shanxi was got by using the GIS technology.The results showed that the basin areas less than 600 meters above sea level were the suitable planting areas of sand pear in Ankang and Hanzhong,which located in southern Shanxi.The climate of low temperature and insufficient rainfall was not good for growth of high-quality sand pear at most of the other regions in Shanxi,so sand pear should not be blind introduced.
