摘　　要：基于1991年—2020年吉林省南部通化地区6个气象观测站的4月、5月降水量及地温数据资料,着重分析研究区域春播期降水量、地温变化的显著特点。结果显示:近30 a的春播期内,通化地区降水量呈总体上升趋势;空间分布上,降水、地温存在显著特点,即南多北少、北低南高;地温春播期除0 cm地温呈缓慢上升的趋势外,5 cm、10 cm、20 cm地温均呈缓慢下降的趋势。Based on the precipitation and ground temperature data of April and May from 6 meteorological observation stations in Tonghua area of southern Jilin Province from 1991 to 2020,the significant characteristics of regional spring sowing precipitation and ground temperature changes were analyzed.The results showed that during the spring sowing period in the past 30 years,the precipitation in Tonghua area showed a general upward trend.In terms of spatial distribution,there are significant characteristics of precipitation and ground temperature,that is,more in the south and less in the north,lower in the north and higher in the south.The ground temperature in the spring sowing period showed a slow rising trend in 0 cm,while the ground temperature in 5 cm,10 cm and 20 cm all showed a slow decreasing trend.
