Abstract: Guangxi is a Camellia nitidissima species most resource-rich area in the world. According to the requirements of growth and development for climate conditions of Camellia nitidissima, the author analyzed and identified the indexes of climate division for Camellia nitidissima planting in Guangxi. Using the climate data from 1961 to 2010 and the geographical information data of 90 weather stations in Guanxi, division indexes were worked out on small grid of 1 km×1 km by GIS, which gave out different values under different geographical conditions. By the function of spatial an analysis and multi-overlapping method of GIS, the climatic regionalization of suitable regions for Camellia nitidissima planting was done, and assessment and suggestions were put forward as a scientific basis for Camellia nitidissima promote the cultivation and production and its optimized distribution in Guangxi. The results showed that: the fitted regions were southern coastal areas, part of the area of the Zoujiang and Youjiang River Valley, and lower elevation areas of the southeast and southwest. The sub-fitted regions were the other southern region. The unfitted regions were northern region, and the southern elevations in the mountains. Suggestions were provided relevant and constructive to the production for Camellia nitidissima.
