Abstract:
On the basis of the rainfall data from 1951 to 2012, in this paper we analyzed the rainfall evolution trend in a typical water-receiving area of East Route of South-to-North Water Diversion Project. We adopted four methods including the moving average method, Mann-Kendall test method, Run test method, and Spearman rank test. Meanwhile we used Morlet wavelet transform to analyze the periodic variation characteristics. The results showed that the rainfall in the region showed an insignificant decreasing trend from 1951 to 2012 and had a 27-year variation cycle. The results have important guiding significance for flood control, drought resisting , agricultural production, and sustainable water diversion for the East Route of South-to-North Water Diversion Project.
