基于生态补水的湿地生态修复效果研究

Study on ecological restoration effect of wetland based on ecological water replenishment

对2010-2012年间刁口河生态补水效果进行分析,研究发现在黄河口地区用生态补水的方式进行生态修复具有很好效果,通过补充黄河水,过水沿岸的地下水水位得到抬升,植被类型优化,景观破碎度、最大斑块类型指数和边缘密度均有所降低,生物多样性得以增加。充分表明基于淡水补给的退化湿地恢复模式在黄河入海口退化湿地区具有有效性。

This paper analyzes the effect of ecological water compensation in Diaokouhe River from 2010 to 2012. It is found that ecological restoration with ecological water compensation in the Yellow River estuary area has a good effect. By supplementing the Yellow River water, the groundwater level along the water is uplifted and the vegetation type is optimized , Landscape fragmentation, maximum plaque type index and edge density were reduced, and biodiversity was increased. It is shown that the restoration model of degraded wetland based on freshwater recharge is effective in the degraded wetland of the Yellow River estuary.
