1950-1990年北京永定河水利工程的环境负效应
Negative environmental effects of water conservancy projects on Yongding River in Beijing from 1950 to 1990
摘要
Abstract
During the period from 1950 to 1990, a lot of water conservancy projects, such as the Guanting Reservoir, the Zhuwo Reservoir, and the Sanjiadian Sluice Gate, were constructed on the Yongding River. These projects satisfied the demands of urban development and the residents’ livelihoods, guaranteed the safety of the lower reaches of the river, and eliminated the possibility of floods. However, they led to the degradation of the ecological environment in the Yongding River Basin. A large proportion of surface water was intercepted, resulting in the decrease of runoff downstream, until the river dried up. The nature of the river has changed and the riverbed has become rough. The groundwater has been over-exploited, resulting in a decrease in the depth to the water table. Land desertification occurred, forming a sand source, and sandstorm disasters intensified. Finally, the Yongding River has gone from having a high amount of water to having a shortage of water, and from being dominated by floods to being dominated by sandstorms.关键词
