This paper discussed the domestic and international research advances on the optimal allocation of water resources at one crop and various crops irrigation，the problem of emphasizing economic benefit and neglecting the ecological environment benefit was analyzed. The author put forward some prospects in studying crop allocating models，multiple objects programming model and ecological influencing should be considered，the water resources optimal decision support system should be made use of, and system dynamic model considering many farm crops should be developed. These will provide science evidence for water saving model and water resource capacity of the certain district and improving the ecological environment.
