水库库址是大地赋于人类的天然财富。要使千万人用血汗换来的“人造湖泊”为四化建设多做贡献,造福于子孙后代,就必须高度重视和认真解决水土流失引起的水库淤积问题。本文是用临沂地区的水库泥沙淤积资料,谈谈淤积对水库寿命的危害以及延长水库寿命的途径。 水库淤积的危害 山东省临沂地区自1959年以来,全区已建成大中型水库47座,总库容39.53亿立方米,总流域面积8425.3平方公里。根据山东水文总站实测水库泥沙淤积资料推算,截至1980年底,
Reservoir site is the earth’s natural wealth endowed to humans. If we want to make more contributions to the four modernizations by making use of the “man-made lakes” that thousands of people exchange for us and make contributions to the benefit of future generations, we must attach great importance to and conscientiously solve the problem of reservoir siltation caused by soil and water loss. In this paper, sediment deposition data of reservoirs in Linyi area are used to discuss the harm of siltation to the reservoir life and the way to prolong the reservoir life. The harm of reservoir siltation Since 1959 in Linyi, Shandong Province, the region has built 47 large and medium-sized reservoirs with a total storage capacity of 3.953 billion cubic meters and a total catchment area of 8425.3 square kilometers. According to the measured sediment deposition data of Shandong Hydrological Station Survey, as of the end of 1980,
