Abstract
干旱是最具破坏性的自然灾害之一,严重影响人民生命财产安全.本研究以珠江流域为例,分别利用标准化降水指数(SPI)和标准化径流指数(SRI)表征气象干旱和水文干旱,评估了珠江流域气象干旱和水文干旱的变化特征,并利用交叉小波探究了遥相关因素对珠江流域干旱的影响.研究结果表明:珠江流域的大部分地区气象干旱呈现减小趋势,流域西部减小趋势显著;大部分地区的水文干旱呈现减小的趋势,东部和西部地区减小趋势显著.1981-2019年,气象干旱的发生频次为22~46次,水文干旱的发生频次为16~43次,但水文干旱的历时和烈度大于气象干旱.厄尔尼诺-南方涛动(ENSO)和太平洋年代际震荡指数(PDO)对各分区的气象干旱和水文干旱影响的时间尺度为8~48个月和8~32个月,太阳黑子(Sunspots)对珠江流域的气象干旱和水文干旱影响相对较小,ENSO和PDO是珠江流域气象干旱和水文干旱的主要驱动力.
