青海位于祖国西北,地处青藏高原北部。解放后,大规模的经济建设,使一个贫穷落后的高寒山区发生了巨大变化,初步形成了一个略具规模的现代化工业、农业、牧业生产基地。大量的人类工程活动使青海发生了深刻变化,但同时也导致了一系列人为灾害,严重影响了生产的再发展,引起了人们的极大关注。 Qinghai is located northwest of the motherland, is located in northern Qinghai-Tibet Plateau. After the liberation, the large-scale economic construction has undergone tremendous changes in the impoverished and outlying mountainous areas, and a slightly large-scale modern industrial production base for agriculture and animal husbandry has been initially formed. A great deal of human engineering has brought about profound changes in Qinghai, but it has also led to a series of man-made disasters that seriously affected the further development of production and attracted great attention from people.
