摘要：

煤矿区多目标复垦模式是提高复垦综合效益的有效途径，但除新增耕地灌溉需水外，还需要解决水资源多目标供需平衡问题。笔者采用动态规划法（DP），对煤矿区多目标复垦的水资源供需平衡分析进行了研究；笔者以徐州九里矿区多目标复垦水资源供需平衡分析为例，通过建立目标函数，按照逆序法从末阶段开始对各个单阶段优化问题依次求解，得到需水和供水间的最优决策方案；该方法解决了多目标复垦的水资源供需平衡和效益最大化问题，有效推进了煤矿区多目标复垦的进行。

Abstract:

Multi-objective land reclamation model of coal mine is an effective way to improve the overall efficiency. Besides irrigation water for farmland reclamation, the multi-objective water resources supply and demand balance is needed to be addressed. The author used dynamic programming (DP), water supply and demand balance of multi-objective land reclamation had been studied in mining area. The author took water supply and demand balance of multi-objective land reclamation of Xuzhou Jiuli mine example, through the objective function was established, law in reverse order from the end of stage, on the order to solve of the problem of various single-stage optimization, the best decision of water demand and supply was obtained. Water supply and demand balance of multi-objective land reclamation and the maximizing effectiveness can be solved by this method, the multi-objective reclamation of coal mine area was effectively promoted.
