摘要
根据１９５１～１９９５年各月降水资料，在全国选取８个代表站，测试了３种单站旱涝指标，并作了相互比较，认为Ｚ指数方法最优．在此基础上，以华北地区为例，选取８０个站点。
By use of the monthly precipitation data of eight sampling meteorological stations in China from 1951 to 1995, the three single indexes for flood and drought were tested and compared with each other. The Z index was recognized to be optimum. On this basis, the 80 stations are selected in North China to discuss the regional indexes and grades which can reflect both the spatial and temporal distribution and intensity for regional floods and drought.
