| 中文摘要: |
| 以经济效益最大为目标，建立灌溉供水量最优分配的分解协调模型。以作物子系统为第一层，建立求解单作物非充分灌溉条件下灌水量在各生育期的最优分配的动态规划模型。然后以区域大系统作为第二层，建立不同作物之间水量最优分配的模型。在此基础上，提出了协调模型求解方法步骤，根据作物布局和地下水分布给出了不同作物在各生育期地下水的最优分配量，以提高区域农业水资源承载能力。 |
| 英文摘要: |
| The maximum economic benefit is set as the objective to establish the dissociation and coordination model for optimal deployment of irrigation water supply. The first level is the crop subsystem, at this level a dynamic planning model for searching the solution of optimal allocation of irrigation water amount in every growing period for single crop under the condition of non-sufficient irrigation is established. The second level is the regional large system, at this level an optimal allocation model of water supply for different crops is established. On this basis, the method and procedure for solving the coordinative model is proposed and the optimal allocation of water supply for different crops according to the distribution of planting and growing period is obtained. By this method the regional carrying capacity of agricultural water resources can be promoted. |
