In this paper,an arodrought index taking water budget and crop water requirement intoconsideration at the same time is put forawrd from the angle of“conditional”water balance and thereality of agricrltural production. In terms of this index, the characteristics of the temporal andspatial distribution of agrodrought and its impacts on agriculture of Hubei Province in the recent30 years are discussed.
