Abstract: Based on the winter meteorological data in 1962-2003 in 77 meteorological stations in Guangdong Province.The integrated chilling injury index for banana was calculated and validated by the Empirical Orthogonal Function and the Wavelet Analysis methods.The results showed that the integrated chilling injury index for banana throughout the Guangdong Province mainly assumed the spatial distribution patterns in a whole consistency as well as in difference between the North Pearl River Delta and the East-west of Guangdong Province.The fluctuation of the integrated chilling injury index for banana was strongest in 1970's and then in 1960's,while it was the weakest in 1980's and gradually became stronger in 1990's.It was found by Wavelet Analysis that the temporal coefficient of the first eigenvector significantly showed a two-four years period in 1970's and in 1990's.The temporal coefficient of the second eigenvector significantly showed a two-four years period in 1970's and in 1990's as well,while it significantly showed a six-eight years period in 1980's.The results would provide foundation for regionalization,evaluation and prediction of the banana chilling injury.
