摘　　要：为了研究冬季南疆果园微环境中的最低气温及其变化特征,从而为果树越冬防寒措施的制定提供参考依据,利用2009~2012年连续3个冬季在喀什地区伽师县、疏附县2个果园内实测的气温数据,就2个果园中最低气温的出现时间、变化趋势和低温持续的时间进行了分析,探讨了伽师果园微环境中测定的最低气温和伽师县气象站记录的标准气温之间的差异。结果表明：1月是当地果园气温最低的月份,2个果园连续3个冬季的最低气温都出现在1月,气温在清晨08：00时至上午10：00时达到当天最低值;伽师果园测定的日、旬最低气温与该县气象站记录的最低气温的变化趋势基本一致,伽师果园中测定的日、旬最低气温始终低于伽师县气象站记录的同期标准气温,其与气象站标准气温的平均温差在3.6~4.1℃之间。s：In order to study the lowest temperature and its change characteristics of orchard microenvironment in the southern of Xinjiang in winter, and to provide a basis for working out some measures for overwintering and cold-proof of fruit trees, based on the actual air temperature data of two orchards in Peyziwat County and Shufu County in winters of 2009-2012, occurring time, change trend and duration time of low temperature were analyzed, and the differences of lowest air temperatures between orchard microenvironment and standard temperature provided by meteorological station were discussed. The results indicated that orchard air temperature was lowest in January, the lowest air temperature of two orchards occurred in January of continual three winters, and air temperature reached the lowest of the day at 08：00-10：00 in the early morning. The lowest temperatures of the day and ten-day period of Peyziwat orchard microenvironment had similar change trends with standard temperatures provided by meteorological station, and always 3.6-4.1 ℃lower than the latter.
