Abstract: In order to objectively evaluate the systematic differences in the area of annual disaster relief before and after the scientific implementation of artificial flood control in the Akesu area of Xinjiang, the effect of artificial flood control in the area was analyzed. This paper uses the data of the annual disaster area of the Akesu area from 1978 to 2013, and starts the year of artificial flood control operation in 1996 as a science. Using the statistical methods such as sequence test, unpaired rank sum test and Welch test, artificial prevention of science The systematic differences in the annual disaster area of each 18a before and after the operation were analyzed. The results show that the hail disasters in the Akesu area are significantly reduced after the artificial anti-mite operation. The non-parametric unpaired rank sum test has a significance level of 0.05, the parametric Welch test has a significance level of 0.01, and the average annual disaster area is reduced by 15063 hm2. The reduction rate was 43.14%. Combined with agricultural economic data, the annual average reduction of disaster relief losses is 281.09 million yuan, the annual input-output ratio is 1:6, and the statistical significance level reaches 0.1. Therefore, after the scientific implementation of artificial flood control operations in the Akesu area, the hail disaster losses are significantly reduced, and the social and economic benefits of disaster reduction are significant.

Abstract: To further evaluate the differences of annual hailstorm areas before and after the scientifically carrying out artificial hail suppression period in Akesu in the hope of analyzing the effect. In this paper, the method of the regression test of areas was applied, the differences of annual hailstorm areas before and after 18a of the scientifically carrying out artificial hail suppression period in Akesu were analyzed with annual hailstorm areas data from 1978 - 2013 in Akesu and Kashi with 1996 as the year of artificial hail suppression. The results showed that the average annual hail area was reduced 23802 hm2, and the relative loss rate was 54.5% after the operation of scientifically artificial hail suppression in Akesu. Combined with the agricultural economic data, the average annual reduction of hail disaster loss was 444,170,000 RMB, annual input and output ratio nearly was 1:10. The statistical significant level highly reached α=0.01. Therefore, through scientifically carrying out artificial hail suppression operations, it is obvious that hail disaster losses reduced and the social and economic benefits are great in Akesu.
