Abstract:: In order to clarify the impact of climate change on spring maize yield in Liaoning Province, based on the meteorological data of 30 stations from 1968 to 2017, and the Standardized Precipitation Evapotranspiration Index, M-K trend analysis, correlation analysis and regression analysis were used to analyze the characteristics of climatic factors, dry/wet changes during growing season and the relationship between those and spring maize yield. The results showed that the precipitation presented a decreasing trend except Dandong. In most areas, the temperature showed an increasing trend, the wind speed showed a significant decreasing trend, and the relative humidity showed no significant changing trend. The sunshine hours showed a decreasing trend except Liaoyang and Benxi. Precipitation, the highest temperature and average temperature were important factors which influenced the production of spring corn in Liaoning Province. Especially in Chaoyang, Huludao, Jinzhou, Fuxin and Dalian, spring maize was more sensitive to these factors. Relative meteorological yield was positively related to the precipitation, and negatively correlated with the highest temperature and average temperature during the growth period in these regions. In the future, less precipitation and higher temperature will be detrimental to the growth of spring corn. As moved eastward, precipitation gradually had a negative effect, while temperature gradually showed a positive effect. Apart from an arid trend observed in some areas of Fuxin, Fushun, Benxi, wetness showed an insignificant trend in the other areas. The spring corn yield in Chaoyang, Huludao and Fuxin was sensitive to the change of dryness and humidity in June and July, and spring corn was susceptible to drought and yield failure. The trend of dryness in Fuxin would make the situation more severe. The trend of wetness in Chaoyang, Fuxin, Jinzhou and Dalian was favorable to the growth of corn. In Shenyang, Anshan, Liaoyang and Yingkou, the dry and wet conditions from May to September influenced the yield, while the dry and wet conditions from June to August affected the yield in Fushun, Benxi and Tieling. These areas were more suitable for the growth of spring corn. Spring corn was vulnerable to waterlogging in Dandong, and the trend of wetting will have a negative impact on maize production in this area. There are positive and negative effects of different climatic factors and dry/wet changes in different areas on spring maize yield in Liaoning Province, and the degree also varies, so reasonable measures suitable for local circumstances should be taken to promote production of the maize all over the province.
