By the principal component analysis(PCA) and correlation analysis, it is found that the main information of Fujian spring precipitation in the last 40 years concentrates on the first two principal components, which account for 83.8% of the total variance. Meanwhile, the correlation coefficients between the first two principal components and the reconstructed spring precipitation of Fuzhou and Xiamen are both significant at a more than the 0.01 confidence level. Therefore, two new precipitation sequences can be constructed by using the sum/difference of Fuzhou and Xiamen rainfall in March and April in recent 100 years to represent the first/second components of Fujian spring precipitation, respectively, and the length of data can be extend to 100 years. Then the multi-time scale features of the reconstructed spring precipitation series are explored by the continuous and orthogonal wavelet analyses and the power spectrum. Results indicate that the first principal component corresponding to the sum serial denotes the drought/flood trend consistent over the whole province with marked quasi-4-year and 24-26-year periods;the second principal component corresponding to the difference serial describes the difference of spring precipitation between southern and morthern Fujian with quasi-2-year and quasi-11-year periods;and in spring drought years, precipitaton over the southern is less than that over the northern. The amount of spring rainfall was remarkably less than the normal in the 1950s-1960s but more in the 1980s. At present it is in the period of normal-less rainfall with less precipitation in the southern than in the northern.
