Abstract: Based on the statistical data of meteorological disasters from 1980 to 2004 in Fujian Province, the main meteorological disasters including drought, flood, typhoon and hailstones, and low temperature freeze were analyzed by using the grey correlation analysis. The results showed that the main meteorological disaster affecting the yield of early rice were typhoon and hailstones, while drought was the main disaster for late rice, single season rice and sweet potato. The drought and low temperature freeze were the main meteorological disasters for the grain production in Fujian Province. However, the impact of drought and flood had been increased since 1995.

Key words: Grain yield, Grain yield, Meteorological disaster, Grey correlation analysis
