摘　　要：利用旅顺口区观测站2004—2016年13年的逐月浅层地温观测数据,分析了旅顺口区浅层地温年、季和月变化特征及其规律。结果表明,2004—2016年近13年各浅层(5、10、15、20 cm)地温年变化呈现先降低再上升的趋势;各浅层地温的月变化总体呈现抛物线类型变化,即从1月的0℃以下逐月上升到7—8月的25℃左右,然后再逐月降低至0℃左右,且4个浅层地温月变化特征相似;各浅层地温四季变化基本一致,差别不超过1℃。春季平均地温为11、12℃;夏季平均地温为24℃;秋季平均地温为15℃;冬季平均地温为0、1℃。各浅层地温总体是冬季最低,夏季最高,春季和秋季在中间,且春季比秋季平均低5℃,这也符合旅顺口区的海洋性气候特征。Based on the monthly observation data of the shallow ground temperature of Lvshunkou District during 2004-2016 ,the annual, seasonal and monthly change characteristics and regulation of shallow ground temperature of Lvshunkou District were analyzed. The results showed that the annual changes of ground temperature in shallow layer（5 cm, 10 cm, 15 cm, 20 cm）in the past 13 years decreased firstly and then increased. The monthly changes of shallow ground temperature generally showed a parabola type,which was from 0 ℃ in January to around 25 ℃in July and August, and then decreased by about 0 ℃ month by month, and the four shallow monthly changes were all very similar, not more than 1 ℃： The average ground temperature in spring was 11℃or 12 ℃ ;the average ground temperature was 24 ℃ in summer;the average ground temperature was 15 ℃ in autumn ;the average ground temperature in winter was 0 ℃ or 1 ℃.The shallow ground temperature was generally the lowest in winter,the highest was in summer, spring and autumn were in the middle, and the spring temperature was 5 ℃ lower than autumn,which was consistent with maritime climate characteristics of Lvshunkou District.
