中文摘要	基于中国西南地区(四川省、云南省、贵州省和重庆市)89个站点1961—2010年的逐月标准化降水指数序列,利用游程理论和Copula函数分析了这一地区不同等级和不同历时干旱的出现概率及重现期特征.结果表明:西南地区的干旱事件多为历时小于4个月、强度小于3的干旱事件;月内轻旱、月内中旱、季内特旱和跨季特旱的概率较大.干旱历时小于3个月和干旱强度为中旱以下的干旱类型多出现在西南地区的东部和西部,而干旱历时大于3个月和干旱强度为重旱以上的干旱类型多出现在西南地区中部.西南地区东部和西部的重现期大于中部地区,且随着干旱历时和干旱强度的增大,重现期空间差异越明显.而且,各气候态下相同干旱类型的概率差值不...
