| Abstract: | To reveal the changes of dry-wet over the past 48 years in Fuzhou area,the data of the annual mean temperature,precipitation and evaportation were used to analyze the trends of the drought index,percentage of precipitation and the difference between evaportation and precipitation from 11 stations in Fuzhou area.The results showed that the change of dry and wet stages was consistent with those of the whole Fuzhou area,and the drought Index decreased wavily.Droughts occurred frequently in 1960s and middle-lat... |
