Tea is one of the main economic crops in China,climate change has an important effect on the growth of tea. By using the data of climate factors from 9 counties during 19812013 in northeastern Fujian province of China, which is the mian production area of tea,and using the method of fuzzy mathematics to construction the model of climate suitability for tea,the paper analyzed its change characteristics of years、decadal and season scale,using the ArcGIS geographic information software to analyze the spatial variation characteristic of the climate suitability of tea. The results show that,it's good that the growth climate conditions of tea in northeastern Fujian province overall, the value of suitability is high. But there are also some restrictions factors,the main climate restriction factors for tea suitable condition in mountainous county are the accumulated temperature,but the coastal counties are relative humidity and drying level. By the impact of climate change,the climate suitability of tea has obvious fluctuations with annual,the decadal amplitude of variation in coastal county tea more than that in mountain county,and its wave more unstable either,the variation trend is more significant than the mountain county. Seasonal characteristics display the climate suitability of tea in spring,summer and autumn are also the volatility increases and decreases in value with decadal,the suitability changes small in spring,but the variation trend change significantly in summer and autumn. According to the effects of climate change on the suitability of tea in northeastern Fujian province, the paper suggest to improve the microclimate conditions of tea garden and strengthen disaster prevention ability to eliminate unfavorable influence of climate change by the infrastructure construction.
