摘　　要：为了全面分析青海海南地区33年来各深层地温的气候变化特征,利用海南州气象台1982—2014年0.8、1.6、3.2 m逐月平均地温资料,对其变化规律进行研究。结果表明:海南地区33年来年各深层地温呈极显著的上升趋势,0.8、1.6 m深层地温表现为夏季增温最为强烈,3.2 m深层地温的春季增温幅度较大。浅层与深层平均地温的年变化趋势,在时间尺度上具有高度的一致性;气温是各深层地温变化的主要影响因素之一,呈极显著的正相关关系,在变化尺度上保持了高度的一致性;总云量对深层地温的变化具有一定的正影响,深层地温的变化受低云量变化的正影响非常明显;用Mann-Kendall检验法检测海南地区各深层地温序列的突变现象发现,均在1998年发生了明显的增温突变。The paper aims to analyze the climate variation characteristics of deep geotemperature in HainanArea, Qinghai for 33 years. The author used the monthly mean geotemperature data of 0.8, 1.6, 3.2 m from1982 to 2014 in Hainan Meteorological Station, and studied its change rule. The results showed that the deepgeotemperature had very significant upward trend in recent 33 years in Hainan Area, but the situation was notin accordance with the seasonal changes, the deep geotemperature of 0.8 m and 1.6 m in summer was thestrongest, and the increase rate of the deep geotemperature of 3.2 m in spring was rather high. Average annualchanging trend of shallow and deep geotemperature on time scales were highly consistent. Temperature was oneof the main influencing factors of the deep geotemperature change, and there was an extremely andsignificantly positive correlation between the two, which maintained a high degree of consistency on changescale. Total cloud cover had certain positive influence on the change of the deep geotemperature, the change ofthe deep geotemperature was affected by the change of low cloud cover obviously. The author used Mann-Kendall test to detect the mutation phenomenon of deep geotemperature sequence in Hainan, it was found thatdeep geotemperature of 0.8, 1.6 and 3.2 m had obviously rising mutation in 1998.
