Abstract:

Camellia is one of the important economic crops in Hunan. Considering the meteorological condition for camellia growth, the annual mean temperature, annual sunshine duration and precipitation of full-bloom stage were used as climate regionalization factor of camellia. Different meteorological factors were interpolated on a 500 m×500 m grid with different mathematic statistic method. Technique of grade division was used on the interpolated small grid data to finish refined climate regionalization for Hunan camellia. The results showed that except for part of Dongting Lake, climate condition in most of Hunan was suitable for planting camellia. Along with increasing temperature in Hunan recently, the area which was suitable for planting camellia would extend and had a big potential.
