Climate change impact assessment has become a universal concern and attracted more attentions all over the world. The climate change has an increasingly serious impact on water resources and grain production. Strengthening scientific research in relevant fields of climate change and enhancing grain production in order to adapt to climate change is of vital significance to guarantee food security, improve farmers' income and maintain social stability. This paper constructs a new economic-climate model based on the original Cobb-Dougla (C-D) production function by adding climate factors, and empirically analyzes the impacts of climate change on grain yield and illustrates regional differences. Constraints of water resource restriction on agricultural yields and agricultural planting structure are also proposed. Based on the analysis of the correlation between climate change and grain yield, the relationship between the use of irrigation water and irrigation is proposed. Human factors such as agricultural technology innovation, policy mechanism guarantee and increase in farmland water conservancy construction investment can mitigate all kinds of negative impacts of climate warming on the Chinese agricultural water to a certain extent.
