摘要(Abstract)：

京津冀地区作为我国的一个重要经济圈,其经济发展和生态环境治理是当前主要关注问题。作为影响生态环境的一个重要因素,对气候变化研究显得尤为重要。基于京津冀地区60 a(1960—2019年)来197个气象站点的逐日平均气温、降雨资料,运用线性回归、Mann-Kendall检验法、小波函数等方法对京津冀地区气温、降雨进行特征分析,并对京津冀地区山区与平原的气候变化特征进行对比。结果显示:京津冀地区近60 a来,降雨量呈现降低的趋势,气温总体呈现上升趋势,并且存在一定周期性;京津冀地区平原与山区气候特征存在较大差异,对比多年降雨量平均值,山区较于平原区减少了100 mm左右,对比多年气温平均值,山区较于平原区气温偏低5℃左右,表明近60 a来城市发展与降雨量的减少、气温的升高密切相关,人类活动对气候变化的影响较为明显,为后期研究城市化、人类活动对气候变化的影响提供一定的借鉴。
