Abstract: In order to discuss climate change influence on climatic suitability of Camellia in Hechi and improve the climate regionalization to provide suggestion for reasonable layout, based on the relationship between climate condition and growth of Camellia in Hechi, the climatic suitable regional indexes for Camellia planting were selected. On the basis of geographic information, climate data of 21 meteorological stations in Hechi and its nearby stations from 1961 to 2010, the climatic models were established. Different meteorological factors were interpolated on a 100 m×100 m grid and Hechi Camellia climatic suitable regionalization was finished by the technique of GIS and expert scoring method. The results showed that: except part north, most of Hechi were most suitable or suitable area, and because of the climate change, the area which was most suitable or suitable for planting Camellia would increase, and extend to north.
