Abstract: Camellia sinensis is one of the most important economic crops in Zhejiang province. During the process of Camellia sinensis growth, early spring frost is the most frequently happened and worst affected meteorological disaster. Based on the predecessors' research achievements and the actual situation of production in Zhejiang province, the meteorological index and hierarchies of Camellia sinensis early spring frost is proposed. With the index and the meteorological data in the 64 meteorological stations around the province, the temporal and spatial distribution of early spring frost of Camellia sinensis in Zhejiang province is analyzed using the negentropy maximization of FastICA. The results show that the variance contribution of independent component 1(IC1) of the overall, mild and moderate early spring frost are 76.65%，49.78%，48.01% and 55.82% respectively. Variance contribution of IC2 is quite low. The variation trend of IC1 of all levels of early spring frost are basically the same. Early spring frost is most likely to happen in North Zhejiang province. During the 41 years, mild and moderate early spring frost occurred every year in Zhejiang province, with a spatial distribution of more in north and less in the south. All levels of early spring frost have increased since 2000. The IC2 of each early spring frost distribute with a minus-plus character. The mild positive value center of overall early spring frost is in the northwest Zhejiang, and middle Wenzhou is negative. The positive values of moderate early spring frost distribute in Jiaxing, east Huzhou, northeast Hangzhou and middle Wenzhou, and south Ningbo and north Taizhou is the negative center. The negative values of severe early spring frost distribute in west Huzhou and southwest Wenzhou, and other areas of Zhejiang are positive. During the 41 years, the mild spring frost displays a decreasing tendency while the moderate fluctuates-- decreased during 1970s and the second half 1980s and increased during the early 1980s, 1990s and after 2000. Severe early spring frost have no obvious tendency. The results could provide a scientific basis for Camellia sinensis production.
