黄河三角洲刁口河生态调水效果评估研究

刁口河是黄河1976年以前的入海故道，其河口三角洲是山东黄河三角洲国家级自然保护区的重要组成部分。为拯救日益退化的刁口河湿地生态，2010年，黄河水利委员会决定利用调水调沙对刁口河湿地进行生态补水。研究采用调水前后实时监测、遥感解译及地下水模型模拟等方法，对刁口河生态调水前后的植被、湿地、土壤含盐量、地下水等因子进行了跟踪评估分析。结果表明，刁口河生态调水效益显著，初步遏制了刁口河退化湿地区域地下咸水入侵的发展态势，一定程度上减轻了区域土壤盐渍化，受损的敏感生境和湿地植被结构得到修复，芦苇沼泽与芦苇草甸等水生鸟类的适宜生境初步形成，水生鸟类多样性显著增加。

Study on evaluation of effect from eco-water supplement to Diaokouhe River in Yellow River Delta

Diaokouhe River is one of the old courses of the Yellow River into the sea before 1976 and its estuarine delta is an important part of the Yellow River Delta National Nature Reserve.To recover the increasingly degenerated ecology of the wetland in the estuarine delta of Diaokouhe River,the eco-water supplement to the wetland during the water and sediment regulation period was decided by the Yellow River Conservancy Commission in 2010.In this study,the follow-up assessments and analyses on the factors such a...
