| 摘 要： | 目的 针对西安浐河下游地区进行的湿地恢复工程,调查研究湿地恢复区的生态环境状况以及湿地水文水质特性,为中国西北地区湿地的恢复与重建提供基础数据和实践经验.方法 采用野外实地观测获得水文资料和湿地恢复区的水质监测数据,分析研究湿地恢复区的水文水质变化情况.结果 湿地水文过程受到浐河径流特性的影响,需要工程清淤措施来调控补给水源,湿地出水流量6×106 m3/y,湿地水位在进水流量变化的影响下,呈现出阶段性涨落变化的趋势;湿地对浐河水质改善明显,总氮、总磷、化学需氧量等6项监测指标从原来的V类或劣V类水质改善达到或接近Ⅲ类地表水水质标准.结论 以浐河为水源,将分布在河道外侧的采砂坑重建为湖泊湿地的方案可行,在恢复湿地地表径流的基础上,湖泊湿地得以重建,恢复区生态环境效益显著,为西北地区的湿地恢复提供了参考.
