b]z BJcMK%i)f"_0【摘要】:为保障工农业生产及人民生活的供水安全,滨州市修建了多处引黄平原水库,规模多为小型或中型,个别水库部分未衬砌,其余水库均为衬砌型式。通过对水库水质的时间、空间变化特征进行分析,结果表明:规模较小水库,多出现汛期水质较非汛期差,营养化程度汛期比非汛期严重;自入库到出库水质逐渐好转;未衬砌水库只是色度、透明度在垂向、水平方向较衬砌水库变化幅度大,其它水质指标变化情况与衬砌型式关系不明显。

滨州市位于鲁北平原,濒临渤海。地下水多为苦咸水,地表水多为Ⅳ类、Ⅴ类或劣Ⅴ水。因此,黄河成为工农业生产、人民生活的主要水源。为保障用水安全,各县区修建了多处平原引黄水库。规模多属小型或中型,除芦河子水库、打渔张水库部分未衬砌外,大部分水库为衬砌型式。1水库概况水利论文kxWHvw
