Abstract: According to statistical analysis of winter temperature, precipitation, sunshine and other elements, combined with winter climate data in 2016 and agricultural disaster survey data of Shouguang, the authors scientifically assess the impact of winter climate resources in 2016 on agricultural production in Shouguang to provide reference for disaster prevention and reduction in agricultural production in winter and spring. The results showed that winter climate characteristics had advantages and disadvantages to agricultural production, on the one hand, the temperature of early winter was a little high, thus winter wheat did not get cold resistance training, which was not good for wheat to live through winter, therefore, strong cold weather led to freeze injury in some areas lately; at the same time, the increase of thick haze, cloudy and rainy weather, and strong cold wave in late January all resulted in the decline of the production and quality of greenhouse vegetables, as well as high vegetable prices; on the other hand, the cold wave and low temperature was good for killing worm eggs, reducing the number of pests living through winter and relieving insects damage; a rare rain and snow in the mid-February of 2016 increased soil water content and alleviated the drought, laying a preferable foundation for agricultural production in spring. Overall, the effects of extreme weather events such as the cold wave, haze, low temperature and sunlight shortage on agricultural production in winter had more harm than good.
