拟建永定桥水库坝址区环境保护研究

修建水库可以蓄水，防洪，对库区附近的工农业生产与人民生活带来便利，而水库水质的好坏是影响周边居民生活用水的关键。在形成库区后水动力条件的改变以及库区库水向周围地质体内渗入，会引起周围生态地质环境的变化，并对水质产生影响。文章提出在流沙河周边山地设立水源地保护带的概念。水源地保护带是指围绕坝址区设置的降低沉积物，污染物和养分进入水文敏感生态系统的重要保护地带。设立该带在于防止此带内或带外地下水出现污染，以保证未来良好水质的持续供水。

The Research of Proposed Yongding River Reservoirs Environment

The construction of reservoirs can not only store water,control flood,but also bring great convenience to the industrial and agricultural production.The key issue which affect the surrounding residents is the quality of the reservoir water.The change of hydrodynamics after the formation of the reservoir area and the reservoir water penetrating in the surrounding geology will impact the water quality and hydrodynamic condition.This paper proposes the concept of setting water protection surrounding mountains....
