Based on the daily climate data in winter and relative meteorological yield of loquat for 2 stations Putian from 1992 to 2009, this paper studied disaster-inducing factors integrated climatic index low temperature injury loquat. The results showed that critical could be determined as 3.0°C. included extreme minimum temperature, sum numbers less than or equal 3.0°C, sustained days harmful chilling accumulation there were obvious correlations among these factors. According method principal component analysis, an was obtained. By correlation analysis Putian, value significantly negatively correlated with loquat, used analyze degree
