In order to achieve synergistic development of water-energyfood-ecology development, this paper identifies connections and feedbacks among water-energy-food-ecology system. Besides, randomness of hydro-meteorological elements is measured by stochastic programming and other uncertain programming. Moreover, the multi-objective programming is developed by maximizing yield, water saving, ecological protection and minimizing energy consumption. It can provide multiple groups of water allocation plans for managers. Compared with other studies, it has advantages in building connections of elements of the synergistic system, and reaching tradeoff amid water saving, energy consumption, food and ecological safety. The model is used to drought irrigation district to verify its application, and proved to be an effective tool to support sustainable development of the water-energy-food-ecology.
