This paper summarizes the research connotation and research strategy of the research on water movement and regional differentiation of agro-ecosystem in the northern region of China. It is proposed that through the comprehensive field experiment and networking research on the water movement and conversion law in the agro-ecosystem in northern China, The water balance of agroecosystem and the mechanism of water cycle. The model of crop productivity under limited water environment in northern China was established. The sustainable development of water run and production and its regional differentiation in northern agro-ecosystem were evaluated.
