摘　　要：调查了中新天津生态城清净湖及其周边水域的盐度背景值,计算得出了常规水生生物的耐盐限值,提出清净湖生态系统重建的方案,即先"蓄水"后"水循环"方案。设计水槽试验,研究水体底泥盐分的溶出规律,得出在蓄水状态下,清净湖底泥向水体返盐的规律,从而得出引进水源的盐度参数,最后根据清净湖周边水源的盐度背景以及清净湖生态系统重建的需要得到具体的控盐方案参数。Based on the salinity value investigation about the Qingjing Lake and ils surroundings in Sino-Singapore Tianjin Eco-City, salt tol- erance limits of conventional aquatic organisms were obtained, the salinity control scheme for the ecosystem reconstruction of the Qingjing Lake ecosystem reconstruction were made, that is, ＂water＂ fi^t , and then ＂water cycle＂. The law of salt dissolution on the water sediments was summarized by designing the Sink experiments, then the conclusion could be drawn as that sediments release salt to water in the Qingjing Lake, and the salinity parameters of the source water to the Qingjing Lake in ＂water＂ period werc got. Finally, salinity background of the lake and its surrounding water sources, as well as specific salt control paramete~ were figured out.
