Abstract：Using precipitation data measured at 36 weather stations and agricultural production data from 13cities/region across Heilongjiang province,we calculated the Z value of annual and seasonable precipitations using the modified Mann-Kendall test method in attempts to analyze the variation of precipitation and its consequent impact on spatio-temporal distributions of drought and flood hazards.The results showed that most regions in the province see an increase in precipitation from winter to spring and a decrease from summer to autumn;the province has more flooding than droughts.Flooding occurs mainly in Shuangyashan,Hegang and Jiamusi in the Sanjiang plain,and drought occurs mainly in Qiqihar in the west of the province.
