摘要:
利用中国气象数据网提供的江西省及周边地区30个气象站点的月气候数据，采用ANUSPLIN软件对各气象要素进行插值获得江西省空间数据，通过对1961—2016年江西省地区降水量、平均气温、最高气温、最高气温进行了时空变化特征分析，结果表明：近56年来，江西省气候变化特征以增温为主，特别是20世纪80时代之后更为显著，最低气温是平均气温增温的主要贡献者；降水量呈波动变化趋势，20世纪60年代为枯水期，而90时代为丰水期；夏季气候变化以降水增加为主，增加速率为20.0 mm/10 a （p<0.05），其他季节以增温为主；空间上，江西省北部地区增温增湿趋势更为显著；各气象要素变化特征在季节上具有一定的空间差异性，春、秋、冬季在江西省北部地区表现为显著增温趋势，夏季在江西省东北部地区增湿增温显著。
Abstract:
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.
