Abstract: It is important to quantitatively assess the climate suitability of tea and its response to climate change.Based on meteorological indices of tea growth and daily meteorological data from 1971 to 2010 in Zhejiang Province,three climate suitability models for single climate factors,including temperature,precipitation and sunshine,were established at a 10-day scale by using the fuzzy mathematics method,and a comprehensive climate suitability model was established with the geometric average method.The results indicated that the climate suitability was high in the tea growth season in Zhejiang Province,and the three kinds of climate suitability were all higher than 0.6.As for the single factor climate suitability,temperature suitability was the highest and sunshine suitability was the lowest.There were obvious inter-annual variations of tea climate suitability,with a decline trend in the 1970s,less variation in the 1980s,and an obvious incline trend after the 1990s.The change tendency of climate suitability for spring tea was similar with that of annual climate suitability,lower in the 1980s,higher in the 1970s and after the 1990s.However,the variation amplitude of the climate suitability for spring tea was larger.The climate suitability for summer tea and autumn tea showed a decline trend from 1971 to 2010.
