摘　　要：在人类干扰活动和气候变化的影响下,官厅湿地生态环境问题日益突出。传统的生态修复技术未能综合考虑整个生态系统,因此研究采用植被修复和改善排水系统技术相结合的综合方法进行治理。经实验表明,植物修复组的TN含量从第一天的3.9 mg/L增加到第8天的4.2 mg/L,之后TN含量呈快速下降趋势减少到3.2 mg/L,TN的含量减少了0.7 mg/L。在硝态氮指标中,相比于普通植物组,植物修复组的水体在12天内硝态氮含量下降了0.8 mg/L。在改善排水系统后,氮含量由改善系统前的5.8 mg/g下降到1.7 mg/g。综上,此次研究的方法技术可以有效保护官厅湿地的生态环境。Under the influence of human interference and climate change,the ecological environment problems of Guanting Wetland are becoming increasingly prominent.Traditional ecological restoration techniques have not comprehensively considered the entire ecosystem,so research has adopted a comprehensive approach combining vegetation restoration and improved drainage system technology for governance.Experiments have shown that the TN content in the phytoremediation group increased from 3.9 mg/L on the first day to 4.2 mg/L on the eighth day,followed by a rapid decrease in TN content to 3.2 mg/L,with a decrease of 0.7 mg/L.In the nitrate nitrogen index,the water in the phytoremediation group showed a decrease of 0.8 mg/L in nitrate nitrogen content within 12 days compared to the ordinary plant group.After improving the drainage system,the nitrogen content decreased from 5.8 mg/g before the improvement to 1.7 mg/g.In summary,the methods and techniques used in this study can effectively protect the ecological environment of the Guanting Wetland.
