淠史杭综合利用水利工程,灌溉部分跨安徽、河南两省,于五十年代开始修建,先在上游建了佛子岭、梅山、响洪甸、磨子潭、龙河口五大水库,总库容66.8亿立米,其中兴利库容28.43亿立米。流域控制面积6460平方公里,多年平均来水量48.2亿立米。佛、梅、响、磨四库水电站装机12.7万瓩,灌区即利用发电尾水及水库与渠首间的区间迳流引水灌溉(区间迳流多年平均7.3亿立米),不足时由水库泄洪孔增加泄水。因此水源是比较可靠的。
淠 Shihang comprehensive utilization of water conservancy projects, irrigation part of Anhui, Henan Province, across the two provinces, began construction in the fifties, first in the upstream built Buddha Ridge, Meishan, Xiang Hongdian, Mozi Lake, Longkou five reservoirs, the total storage capacity 6.68 billion cubic meters, of which 2.343 billion cubic meters of profit and storage capacity. Watershed control area of 6,460 square kilometers, the average annual water volume of 4.82 billion cubic meters. In the irrigation area, 127,000 tons were installed in the four reservoirs of Buddhism, Mei, Xiang and Mud. The irrigated irrigation area utilized the power generation tailrace and the inter-section flow diversion irrigation between reservoirs and the canals (with an interval of 700 million cubic meters for many years) Increase drainage. Therefore, the water source is more reliable.
