几年前,一位地质工作者在《中国国家地理》杂志上发表的《巍巍大坝,安乎危乎?》文章中曾指出:“四川岷江上的紫坪铺水库坝高156米,库容9.63亿方,其上游还有一系列的梯级大坝,面对岷江上游曾多次发生7级以上地震的强震区和大规模山崩堵江溃坝的历史背景,一旦类似叠溪、松潘大地震的事件重演,后果将不堪设想。”这让很多人对我国西南地区的大规模水电建设感到十分担心。
A few years ago, in a paper published in the “China National Geographic” magazine, a geological worker pointed out: “The Dam of Zipingpu Reservoir on the Minjiang River in Sichuan Province is 156 meters high and its storage capacity 963 million square meters. There are a series of cascade dams on the upper reaches of the dam. In the face of the historical background of the strong earthquake zone where there are many earthquakes of magnitude 7 or above and the large-scale landslide and dam break in the upper reaches of the Minjiang River, The consequences will be disastrous. ”This makes many people feel very worried about the large-scale hydropower construction in southwest China.
