【摘要】 利用1951—2017年济南市逐日气温、降水、日照时数观测资料,分析讨论了济南67 a济南地区农业气候资源时间和空间的变化及差异。结果表明:67 a来济南平均气温是14.6℃,整体呈阶段性上升趋势,1986—2002年增温明显。≥0℃活动积温呈震荡性上升趋势,夏季作物旺长的≥10℃活动积温也呈上升趋势,对作物生长有利,67年来济南水资源变化总体来说不明显,平阴、济阳、商河三县有偏少趋势。总体来说,济南气温升高蒸发量会增大,降水量变化趋势不明显,尤其平阴、济阳、商河,会出现旱情。更多还原

【Abstract】 Based on temperature,precipitation,and sunshine hours observation data of Jinan during 1951-2017. The changes of time and space of agricultural climate resources in Jinan in 67 years were analyzed. The results showed that the average temperature in Jinan was 14.6℃ in the past 67 years,and the overall trend was gradually increasd. The temperature increased significantly from 1986 to 2002.The activity temperature ≥ 0℃ showed an upward trend,and the temperature ≥ 10℃ in summer crops was also rising,which is favorable to crop growth. The changes of precipitation in Jinan in the past 67 years were generally not obvious. There were few trends in Pingyin,Jiyang and Shanghe. In general,high temperatures would lead to greater evaporation,no increase in precipitation,and drought would occur.更多还原
