7、工程项目环境影响评价论证阶段，国内外专家己对三峡工程本身带来的环境问题进行了详细的调查分析与研究，取得了丰富的研究成果，但是，由于受多种复杂因素的影响，迄今为止，有关三峡工程对未来库区水质状况的影响程度，尚没有一个十分明确及定量化的结论，因而库区未来水质问题依然是当前研究的一个热点课题。3杨志，陶江平等.三峡水库运行后库区鱼类资源变化及保护研究J,人民长江，2012,43（10）.中文摘要：结合历史资料以及现状调查资料，分析了三峡库区形成后，库区江段鱼类资源变化的特征，以及造成库区鱼类资源变动的主要因素，并对库区鱼类所面临的主要生态环境问题进行了辨识。针对水利工程开发对鱼类生境造成的影响，提出

9、、总氰化物、砷、汞、六价铬、石油类、铅、镉、氨氮、高锰酸盐指数、总磷、总氮等16项水质指标的检测，将监测结果与往年同期总体水质和背景浓度进行比较。结果发现三峡水库135m蓄水前后总体水质仍属、类，无明显变化。影响库区总体水质的主要污染因子是总磷、总氮。结论：三峡水库135m蓄水未对库区长江水质造成显著的负面影响。5 马占山，张强，秦琰琰. 三峡水库对区域气候影响的数值模拟分析J，长江流域资源与环境，2010，19(9).中文摘要：利用中尺度数值模式模拟了三峡水库建成后，由于下垫面变化对区域气候的影响，并探讨了三峡水库的建成是否为引发社会广泛关注的高温干旱和低温雨雪冰冻灾害等极端天气的主要因素。

10、研究表明：三峡水库的建成对当地气温具有海洋性效应，库区附近春季温度变低，夏季在水库下游气温升高、上游则气温降低，而冬季则以升温为主；春季降水变化主要位于库区沿线的南部山区，增雨带和减雨带相间分布，夏季降水量在三峡库区中上游地区和附近的山区呈增加趋势，在库区下游及附近地区降水呈减少趋势，冬季降水量减少，主要集中在大坝附近地区到三峡（巫山）段；春季库区的相对湿度增加，幅度多在，夏季相对湿度的影响也存在正负两种效应，大坝上游库区附近相对湿度增加，大坝下游地区相对湿度降低，冬季变幅不大；三峡水利工程不是干旱、低温雨雪冰冻等极端天气出现的主因，它对极端天气事件的影响并不明显。4.2 检索工具维普中文科技
