【摘要】 分析电厂运行前后及引滦前后电厂温排水和引滦调水对陡河水库水体富营养化的影响 ,证明水库温升和库容减少加剧了库区水体的富营养化进程。引滦入陡河使水体运动加速 ,温升幅度缓解 ,从 1983～ 1985年的富营养化状态向中富营养化状态回落。但水体中营养盐超标以及水库受温排水影响所造成的全库性温升仍为不利因素。最后提出了营养盐的控制措施及改善水库换水周期 ,加强水库水质和水温监测的建议。更多还原

【Abstract】 Analyzed are the influences of thermal discharge from a power plant and water diversion from the Luanhe River on the eutrophication of the Douhe Reservoir. It is shown that the increase in water temperature and the decrease in reservoir capacity aggravate the process of eutrophication. Water diversion from the Luanhe River accelerates water movement and alleviates temperature increase, greatly decreasing the degree of eutrophication in the reservoir during 1983～1985. In consideration of existing unfavorable factors, such as high contents of nourishing salts and the temperature increase caused by thermal discharge into the reservoir, suggestions of the regulation of reservoir water exchange period and the strengthening of water quality and temperature monitoring, and measures for nourishing salt control are proposed.更多还原
