摘要
为实现黑河水生态环境的优化管理,以其尾闾湖东居延海为研究对象,分析其水质在时间和空间上的变化,并对其可能的影响要素进行了评价.研究结果表明:生态输水明显改善了东居延海湖水水质,大部分湖区矿化度减小,入湖口矿化度由1985年的10.50g/L下降为2016年的5.45g/L;东居延海水质改善主要受黑河来水量的稀释作用影响,而部分水质指标值增大则主要受黑河来水水质的控制.
As a major component of the oasis ecosystem, the terminal lake in the arid area affects the ecological environment of the region. In order to realize the optimal management of the Heihe River ecological environment, this paper analyzed the spatial-temporal variation charac-teristics and influencing factors of water quality of East Juyan Lake. The results show that ecological water transport significantly improves the water quality of the East Juyan Lake, and the mineralization degree decreases, especially in the lake entrance, with the salinity decreasing from 10.50 g/ L in 1985 to 5.45 g/ L in 2016. The improvement of water quality is mainly affected by the dilution of upstream water, while the increase of some water quality indicators's concentration is mainly affected by the quality of the upstream water.
