Abstract:Using the daily mean temperature, sunshine hours and relative humidity data from 46 meteorological stations in Jilin Province from 1961 to 2015, and based on the previous studies on the climatic index of rice quality in northeast China, the changes of the climatic resources of rice quality in Jilin Province in recent decades and the evolution of comprehensive evaluation results of the climatic resources of rice quality were studied in the paper. The results showed that the average temperature in rice grain filling period in Jilin Province has an increase trend from 1961 to 2015, and about half of the stations passed the significant test of 0.05 level. The average daily total solar radiation varied widely, but most of the changes were not significant. Relative humidity generally showed a downward trend, and 30 stations passed the significant test. According to the comprehensive evaluation of the average rice quality climatic resources in Jilin Province from 2011 to 2015, the comprehensive evaluation of most areas reached level Ⅰ-Ⅱ, of which level Ⅰ accounted for 80.4% of the statistical site. In all the years, the quality of the climatic resources were very superior, except for the 1970s, the comprehensive evaluation of the climatic resources of rice quality at more than 76% of the sites reached the level Ⅰ, and more than 87% reached level Ⅰ-Ⅱ. In particular, during 2011-2015, the level Ⅰ-Ⅱ accounted for 91.3%, of which 80.4 % were level Ⅰ.
