| 【目的】揭示公明水库的蓄水、供水、生态交换水量、损失水量之间的相互关系，分析其储备效益、供水效益和生态效益等。【方法】考虑深圳北线引水的不同选择，设置2种城市供水情景，其中情景1为近期北线引水固定不变，以供定需；情景2为远期北线引水有丰枯变化，以需定供满足城市供水要求。通过建立公明供水调蓄工程水库群优化调度模型，用45年长序列月径流资料采用决策动态优选的自适应算法求解模型，并将计算结果与采用水量平衡中的等流量常规调度结果进行对比分析。【结果】2种情景的优化调度结果表明，公明水库的多年平均蓄水量有很大的差异，由情景1的10 715万m3/年增加到情景2的12 545万m3/年，平均每年增加1 830万m3，情景2的蓄水量已经超过了12 141万m3的储备库容；城市供水保证率由情景1下的0.70%～6.70%提高到情景2下的98.00%，最大连续缺水破坏时间由情景1的45年锐减到情景2的0年，满足了该地区的城市供水要求。【结论】通过水库群联合调度，深圳公明供水调蓄工程能够实现对深圳市中西部城区供水和储备水源等目标，并能发挥其生态效益。 |

| Abstract: |
| 【Objective】This study revealed the relationship between water storage,water supply,ecological exchange water and loss of water of Gongming water storage project,and analyzed its reserve benefit,ecological benefit and water supply benefit.【Method】Two water supply scenarios were set based on the options of water import from north.One used supply amount to decide demand amount with fixed quantity of water from recent northern line,and the other one decided supply amount based on demand amount assuming that the quantity of water from future northern line would change.Then an optimal operation model of multi-reservoir was built,and 45 years monthly runoff data were used to solve the model using adaptive algorithm of decision dynamic optimization.The model results were compared with measurements at last.【Result】The multiple-year-average water storage capacities of Gongming reservoir were different under the two scenarios.The capacity increased from 107.15 million m3 per year in scenario 1 to 125.45 million m3 per year in scenario 2 with a net increase of 18.30 million m3 per year.The storage capacity in scenario 2 was larger than the reserve capacity of 121.41 million m3.The city water supply guaranteed rate increased from 0.7%-6.7% in scenario 1 to 98% in scenario 2,while the maximum water shortage time decreased from 45 years in scenario 1 to 0 in scenario 2.The city water supply requirement in the region was totally met.【Conclusion】Through joint operation of reservoirs,the Gongming water storage project could realize the water supply and water reserve targets of Midwest Shenzhen and exert their ecological benefits. |
