Absrtact: Fujian Province is one of the largest tea production areas in China.The local tea planting area and production are prominent in China.The tea industry is also an important part of the local economy.Agriculture is a meteorological sensitive industry,so tea production will undoubtedly be affected by the climate.Tea yield fluctuations reflects the climate change on the tea plant environment and growth conditions to a certain extent.In order to explore the influence of climate change on tea production,daily observation data of 19 meteorological stations in Fujian province from 1961 to 2015 is selected and studied for Fujian’s temporal and spatial climate changes.The temporal variation of climate in Fujian province was studied using the linear trend method.The spatial distribution of temperature and precipitation in Fujian province was studied by using ArcMap,and using MATLAB to do Wavelet analysis to Study periodic changes of temperature and precipitation.Then,according to the climate change trend,the influence of climate change on tea production is analyzed,and the scientific and reasonable suggestion on tea production in Fujian province is put forward.The results show that the temperature and precipitation of Fujian province has increased in recent 55 years.The increase of temperature and precipitation shows the trend of climate warming and wetting,and the temperature and precipitation have obvious periodical changes at different time scales.Climate change has two sides effect on tea production.The increase of temperature and precipitation will make the tea production conditions in Fujian more suitable.However,extreme hypothermia and abnormal precipitation can also lead to a reduction in tea production.

Key words：Fujian;tea;climate change;Wavelet analysis.
