Abstract: Comparing the ecological conditions of the tea-producing area in Xinyang with that in the other places in China，we have obtained the following conclusions:(1)The temperature is one of the most important factors that affect the tea quality，and the temperature of the Northern Sub-tropical Zone is one of the best for high quality teas. (2)The Xinyang tea-producing area which is located in the Northern Subtropical Zone has favourable moisture condition and fogs，and is a suitable area for high quality tea production.(3)The landforms in Xinyang tea-producing area are mostly low-mountains and hills;the area of land suitable for growing tea is large and the farming intensity of land is low. Therefore,the Xinyang tea-producing area is a high quality tea-producing area. (
