Abstract: The characteristics of climate factor changes,including its trend,phase and periodicity,affecting sugarcane(Saccharum officinarum) yield and sugar content was analyzed in Zhanjiang for the last 55 years.The results showed that there was an obvious increasing trend in accumulated temperature from March to October,while there was an obvious phase in total precipitation and accumulated temperature from March to October,and there was an obvious periodicity in total precipitation,accumulated temperature,total sunlight hours and quantity of gust from March to October,total sunlight hours existed periodicity of 11 and 3~4 years,quantity of gust existed periodicity of 5~6 and 7~8 years.The mean minimum temperature from October to November had faint increasing trend.The precipitation from November to February following year had a significant phase and a periodicity of 2~3 years.
