摘　　要：三峡水库蓄水水位已达165米,其水环境性质为半封闭型的缓流水体,水体自净能力下降。库区次级河流水质的状况直接影响着三峡库区的水环境与生态安全。在分析库区次级河流水体富营养化现状与发生条件的基础上,结合国内外河流整治的生态观念和思路,对库区次级河流污水生态工程治理技术进行了的初步探讨。At present, the water storage level in the Three-Gorge Reservoir （TGR） has reached 165 meters. The TGR has changed into a semi-closed water body with slowing flow, and self-purification ability of water TGR dropped accordingly. The water quality of secondary river becomes one of the direct effects for ecological security in TGR. Based on the analysis of status of eutrophication and happening conditions of secondary river in TGR, ecological engineering technologies for water treatment are discussed in the paper combined with the ecological concepts and routes in the field of river basins at home and abroad.
