摘　　要：以东营气象站1967-2011年气温与降水量实测资料为基础,采用滑动平均、趋势分析等方法,对黄河三角洲湿地近45年的气候变化特征进行分析。结果表明,20世纪60年代以来,该区域气温有显著升高趋势,倾向率为0.491℃/10a,年降水量有微弱的减少趋势,倾向率为-2.362 mm/10a;气候要素的综合变化使黄河三角洲湿地区域的湿润系数有比较显著的降低趋势;黄河三角洲湿地水循环诸要素中,人工补给量和渗漏量变化不大可忽略不计,降水量和上游来水量均处于减少状态,水分支出中蒸散发量呈增加趋势,且年均降水量少于蒸散发量,上游来水量少于入海量,湿地水循环整体处于＂入不敷出＂的状态。Based on the weather data from 1973 to 2011 in Dongying meteorological station,this article analyzed the climate change characteristics in the wetland of Yellow River Delta in the last 45 years,by using methods such as moving average and trend analysis. The result showed that the temperature has a visible ascending trend with the rate of 0. 491 ℃ /10 a and the precipitation has the tiny descending trend with the rate of-2. 362 mm /10 a. The coefficient of humidity has downtrend in the wetland of Yellow River Delta area since 1973. On this basis,this paper carries out a further discussion on the response of the wetland water cycle to the climate change in the Yellow River Delta,the amount change of artificial recharge and leakage was negligible,both the precipitation and upstream inflow were in the reducing state,besides evapotranspiration showed an increasing trend,and the average annual rainfall was less than evapotranspiration,upstream inflow was less than the one into the sea,which made the wetland water cycle a ＂ make ends meet＂ state.
