Based on the monthly climate data of 30 meteorological stations in Jiangxi Province and surrounding areas provided by China Meteorological Data Network, the spatial data were obtained through interpolating the meteorological elements by the ANUSPLIN software. We analyzed the temporal and spatial variation characteristics of annual, seasonal and monthly precipitation, average temperature, maximum temperature and maximum temperature in Jiangxi Province during the period from 1961 to 2016. The results showed that the climate change characteristic of Jiangxi Province had been dominated by warming in the past 56 years, especially after the 1980s. The increasing rates of average, maximum and minimum temperature were 0.196, 1.169, 0.25℃/10 a, respectively, and minimum temperature was the main contributor to average temperature increase. Precipitation showed a fluctuating trend with the rate of 31.5 mm/decade (p>0.05). In the 1960s, it was a dry period, while it was a flood one in the 1990s. The increase of precipitation mainly occurred in summer with the value of 20.0 mm/decade (p<0.05), but average temperature did not change significantly in this season. The increase trends of minimum temperature in the four seasons were significant (p<0.01), especially in winter, which was 0.34℃. The maximum temperature increased significantly in spring and winter, and the increase trend in spring was larger than that of minimum temperature. From the perspective of spatial distribution characteristics, the trend of warming and humidifying in the northern part of Jiangxi Province was more significant. The variation characteristics of meteorological elements had certain spatial differences in the seasons. The warming trends in the northern part of Jiangxi Province were significant in spring, autumn and winter, and the humidification and warming in the northeastern part of Jiangxi Province were significant in summer.
