闽江水利工程的环境水质效应问题

Some environmental problems concerning water quality effected by construction of water conservancy projects along the Minjiang River

闽江干 -支流上众多水利工程的建设与运营 ,明显地影响了河流的水动力场因素和水化学场因素 .对河流地质作用类型与强度产生了强烈的影响 ,引发了沿江水文地质环境状况的变化 .使河流水体纳污、稀释扩散自净能力受到较大的影响 ,河流出现受污染程度日益加重、水环境恶化的趋势 ,使沿江城市和乡镇的水文环境质量受到明显的影响 .就此讨论了与水利工程建设和运营有密切关系的环境水文地质问题中的环境水质效应专题 .

Due to the construction and operation of many water conservancy projects along the tributary and master stream of the Minjiang River , the type and intensity of river geological function are strongly affected . The hydrodynamic and the hydrochemical fields of the Minjiang River are markedly changed. The capacity of dirt-admittance, diffusion and self-purification of the Minjiang River is influenced , and the environmental quality of cities along the Minjiang River is obviously damaged. In the paper , the characteristics , regularity ,genesis and prophylactic-therapeutic measures of environmental hydrogeology problems, which are closely related to water conservancy projects along the Minjiang River, are discussed and analyzed.
