| Abstract: | A drought index equation has been established by using departure perentage of precipitation.It can be used to monitor the drought state in arid and semiarid regions.A good result has been obtained by using the equation to calculate and analyze the drought state of north part of Xingjiang during 1989 and the wet and dry periods of Urumqi over the years. |
