| 摘要: |
| 阐述了国内外优化灌溉制度及灌溉水资源在单一作物和多作物间优化分配模型的研究进展，分析了目前水资源优化分配模型研究中存在的仅考虑经济效益而忽略生态环境效益、农业用水效率较低、模型中指数取值研究不足等问题，提出了今后在农作物水资源优化分配模型的相应研究中，应考虑多目标规划模型及生态影响目标，并运用决策支持系统来进行水资源优化，发展多作物优化组合及优化配水模型，从而为确定区域节水模式和水资源承载能力及牛态环境改良提供更有力的科学依据。 |

| Abstract: |
| 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. |
| Key words: optimal allocation of water resource optimal irrigation schedule dynamic planning model linear model non-linear model |
