Abstract: The paper aims to study the effect of meteorological conditions on twelve consecutive peaks of rice yield in Changzhou. The authors used statistical analysis, literature consulting and SPSS software to comprehensively analyze the suitability degree of meteorological elements, the degrees of agrometeorological disasters and meteorological contributions to rice yield by rice growth indexes based on data of annual rice yield and meteorological observation from 2003 to 2014. The results showed that: (1) in general, the meteorological elements were suitable for rice growth during these years, the day number of accumulated temperature above 0℃ was more and the day number of sunshine duration was less than annual mean value, but the low degree percentages of sunshine duration were greater than -15% in 90.9% of the years, meanwhile, compared with annual mean, rainfall was less in half of the years, normally, the condition with more rain in jointing to booting stage and less rain in heading to maturity stage was beneficial to high rice production; (2) the influence of agrometeorological disasters was slight during these years, according to the warning threshold of agrometeorological disasters during rice growth, it was found that mild degree of meteorological disaster accounted for the majority, while moderate and heavy degree had an increasing tendency in jointing to booting stage; (3) 3 fitting models, including linear equation, quadratic term equation and three term equation all showed that the meteorological production in most years was a positive contribution to the actual rice yield. Thus, the contribution of meteorological conditions to rice yield in Changzhou was positive among the twelve years with the highest rice yield.
