| 摘 要： | 通过对扎龙湿地冰封期进水口、核心区水样的采集及水质指标的测定，分析了冰封期水环境特征，结果发现，冰封期总氮、总磷、氨氮、高猛酸盐指数的超标率为100％，BOD5的超标率为80％，总氮超标4．98～45．93倍，总磷超标3．10-41．80倍，氨氮超标3．62～53．50倍，高锰酸盐指数超标4．52—15．80倍，BOO5最高超标倍数为2．54倍，进水氮、磷超标倍数最多，核心区仙鹤湖的高锰酸盐指数和BOD5超标倍数最多，东升水库的生物量最高。扎龙湿地冰封期水环境污染严重，亟需采取有效措施保证湿地供水，恢复湿地水生态系统对污染的缓冲能力，防治水体富营养化，同时，加强水环境管理，提高湿地保护的公众意识，以便更有效地保护扎龙湿地生态系统。

| Abstract: | Water samples of the inlet and core area were collected and water-quality index were determined in ice sealed.The water quality of ice sealed was analyzed and it was found that the over standard percentage of total nitrogen(TN),total phosphorus(TP),ammonia nitrogen(NH4-N),Chemical oxygen demand(CODMn) was100%,and biological oxygen demand(BOD5) was 80%,the over standard times of TN,TP,NH4-N,CODMn was 4.98~45.93,3.10~41.80,3.62~53.50,4.52~15.80,respectively,and the highest over standard times for BOD5 was 2.5... |
