摘要:根据河南省20多个气象站1963-2012年的基本气象资料以及自然灾害数据库,在其中选取河南省典型站点数据,计算河南省1963-2012年月尺度综合气象干旱指数(CI),分析干旱发展规律和干旱演变特点.结果表明河南省50年间除郑州外CI指数呈上升趋势,干旱加剧,年代间有往复波动;三门峡受地域影响干旱程度较轻.
According to the basic meteorological data as well as the natural disaster database in more than 20 stations in henan province from 1963 to 2012, in which the selected typical site data in henan province, calculate scale integrated meteorological drought index (CI) and analyzed regional development rule of drought and drought evolution characteristics from 1963 to 2012.
