本文介绍了魁北克水电局在魁北克境内所管辖的许多大水库的运行。这些水库水位变辐大、滞洪期长,对下游电站十分有利。文中阐述了魁北克省的三个自然地理区域,即前寒武纪地盾,圣·苏伦斯洼地和阿帕拉契山区,文章结合地文地质构造以及所掌握的一些具体资料,对这三个截然不同的自然地理区域所兴建的一系列水库可能发生侵蚀的背景作了探讨。 This article describes the operation of many large reservoirs under the jurisdiction of the Quebec Hydro Authority in Québec. These reservoirs have large water level variations and long flood detention periods, which are very favorable to downstream power plants. The paper describes three natural geographical areas of Quebec Province, that is, the Precambrian shield, the St. Surunshwa depression and the Appalachian mountains. Combined with the geology and geology of the geology and some specific data, The background of a series of reservoirs that may be eroded by different natural geographical areas is discussed.
