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.
