2012年8—9月对大伙房水库入库河流39个河段的物理生境特征和水质状况进行调查,并运用相关分析和冗余分析的方法识别物理生境特征与水质状况的响应关系.研究结果表明,大伙房水库入库河流物理生境质量等级为较好以上的河段占43.6%,一般河段占48.7%,较差河段占5.1%,物理生境质量好的河段主要位于浑河上游地区,质量较差的河段主要位于大伙房水库周边地区.大伙房水库入库河流总磷(TP) 、氨氮(NH_4~+ -N) 、总氮(TN)多符合国家Ⅱ类地表水环境标准,五日生化需氧量(BOD_5)和化学耗氧量(COD_(Cr))较高,部分点位超过了国家 Ⅲ类地表水环境标准.大伙房水库入库河流物理生境特征与水质状况显著相关,物理生境...

Physical habitat conditions and water quality were examined in 39 reaches in the rivers flowing into the Dahuofang Reservoir from August to September 2012. Correlation analysis and redundancy analysis were used to identify the relationship between physical habitat characteristics and water quality. The results show that physical habitat quality of all reaches was 43.6% for good, 48.7% for fair, and poor 5.1% for poor. The reaches with good water quality were mainly located in upstream of the Hun river, and those for poor were located in the sur...
