  "abstract": "目的旨在探究滇东南岩溶区极端气候的变化特征及成因。方法基于滇东南岩溶区内的16个气象站点1969—2018年的日最高气温、最低气温和降水量，选取12个极端气候指数，采用线性倾向估计、Mann-Kendall突变检验、Morlet复小波分析、反距离权重插值、Pearson相关分析、相干小波和交叉小波变换的方法分析该区极端气候指数的时空变化特征及其与大气环流因子之间的关系。结果1）1969—2018年滇东南岩溶区年平均气温呈上升趋势，年总降水量呈下降趋势，极端气温暖指数呈上升趋势，冷指数呈下降趋势，大部分极端降水指数呈下降趋势，降水强度（SDII）呈缓慢上升趋势。极端气温和降水指数大部分突变点集中在20世纪80年代至21世纪初，极端气温指数存在1~5个周期，介于5~25 a；极端降水指数存在3~5个周期，介于4~31 a。2）极端气温暖指数在研究区西南部上升更为明显，极端气温冷指数中冷夜日数（TN10p）、冷昼日数（TX10p）在西南部下降更为明显，霜冻日数（FD0）在北部下降更为明显，极端降水指数在研究区西南部下降更为明显。3）大气环流因子与滇东南岩溶区极端气候指数存在多个显著振荡周期，大西洋多年代际振荡（AMO）对滇东南岩溶区极端气候指数影响最大，AMO与滇东南岩溶区极端气温暖指数呈同相位的变化，冷指数呈负相位的变化，大部分降水指数呈负相位的变化关系，AMO对研究区东北部和西南部极端降水影响显著。结论滇东南岩溶区呈暖干化趋势，区域极端气候的变化受大气环流的调控，不同环流因子对滇东南岩溶区极端气候的影响存在差异性。",
