Abstract:
In order to objectively evaluate the hail suppression effect in Bole Area of Xin-jiang,the statistical approaches such as simple sequential test,unpaired W-M-W test and t-test,are used with the data of the annual hail damaged areas during 1976?003 in Bole area of Xinjiang,in which the hail suppression operations were carried out during 1989?003, and were not carried out during 1976?988.It is shown that the annual mean hail damaged areas have been reduced by 841.53hm2,about 26.56%.The statistical significance level i>α= 0.05.Therefore the hail suppression effect in the area is significant.
