Teaplanting land use or tea garden is one of the dominating land use type in Yunnan mountainious region. It is significant about suitability evaluation and analysis for tea garden land scientifically integrated with mountainious land resources feature, since it is benefit to distribute mountainious land resources use by adjust measures to local conditions and promote local mountainious land resources sustainable use for long time. The study chose tea garden land suitability evaluation of Ning'er county in Yunnan Province as the research target. Based on the analyzing of the relationship between tea plant growing and natural condition and the condition of tea garden maintenance, the paper chose land suitability evaluation indexes of tea garden. The annual temperature, annual rainfall factor were simulated using ARCGIS interpolated method. The evaluation quantitative classification table was build with the annual temperature, annual rainfall, soilt, slope, irrigation water sources and road accessibility. Finally, integrated use ARCGIS spatial analysis, spatial jion assigned the scores of each role to evaluation unit polygons, and calculating the general score of the factors, to achieve the tea garden land suitability evaluation. Analysed the spatial layout of the evaluation results: the study area can be divided into the most suitable areas, sub-suitable areas, critical suitable areas and unsuitable areas, and further analysis and discussion of the evaluation results was done.
