Geography Distribution and Ecotypes of Wild Tea Resources in Guizhou

The vegetation type,natural distribution rule and morphological character of wild tea resources and relationship between the suitable growth condition and variety were investigated based on the topographty and climate characteristic in Guizhou.The results show that the wild tea resources are distributed in the areas with an elevation of 1000～1900 m,4000～5500℃ of annual accumulated temperature(≥10℃) and ≥-10℃ of extreme temperature.The wild tea resources under the specified natural eco-environment condition have the special characteristic of social and economic value by analyzing morphological characters and biochemistry components.
