Abstract: his research analyzed the temporal and spatial variation characteristics of total solar radiation, accumulated temperature above 10℃, precipitation and temperature diurnal range during growing season of summer maize and their effects on meteorological yield of summer maize in Huaibei area of Anhui Province, by the means of climate tendency rate, M-K mutation test, correlation analysis and regression analysis, based on the data include daily meteorological data on 24 meteorological stations in Huaibei area of Anhui Province from 1961 to 2018,as well as the yield data for summer maize of corresponding cities (counties) from 1961 to 2014. The result showed that (1) for summer maize in Huaibei Area of Anhui Province during 1961-2018, the total solar radiation and temperature diurnal range both declined significantly (P<0.01) in the whole growth stage, vegetative stage, vegetative and reproductive stage, as well as the reproductive stage. And the accumulated temperature above 10℃ and precipitation increased insignificantly (P>0.05). In terms of spatial distribution, the total solar radiation and temperature diurnal range gradually decreases from north to south; The spatial variation of accumulated temperature above 10℃ was not significant; The precipitation generally showed radial distribution, while the high value area was located in the east of Huaibei. (2) In recent 58 years, the total solar radiation and diurnal range of summer maize in Huaibei region of Anhui province mutated from a large amount to a limited amount in 1981 and 1982 respectively, and decreased by 220.1 MJ·m^-2 and 0.7℃ respectively after mutation; And there was no obvious mutation in the accumulated temperature above 10℃ and precipitation. (3) Precipitation is the main meteorological factor that affected the summer maize meteorological yield in Huaibei area，and had quadratic relations between meteorological yield. The accumulated temperature above 10℃ had a negative effect on the meteorological yield for summer maize，reaching a significant level (P < 0.05) in vegetative and reproductive stage. Meanwhile, the influence of total solar radiation and diurnal range is insignificant. The comprehensive effect of change for climatic resources on meteorological yield of summer maize reached significant level (P <0.05) in the whole growth stage as well as the vegetative and reproductive stage, and reached extremely significant level (P <0.01) in the reproductive stage. (4) In the process of summer maize planting, strengthening construction of water infrastructure can contribute to the improvement of the ability to control water, thus the meteorological yield for summer maize in Huaibei area would increase.
