Responses Analysis on Groundwater Level Fluctuations in Coastal Wetland
We analyzed the relationship of groundwater level of wetlands at the Yellow River mouth to the ocean tide responses, as well as its impact on the spatial distribution of wetland types by field positioning observations of coastal wetland groundwater levels. The results showed that, the groundwater level is significantly affected by the tides. Its fluctuation has a negative polynomial relationship with its distance to the coast. Their correlation reached maximum during spring tide (R2=0.79); the closer to the coast, the greater the groundwater level fluctuation is, the greater the interaction between the seawater and the groundwater, the smaller the groundwater depth; In contrast, the further from the coast, the smaller the level fluctuation is, the greater the groundwater depth level. The spatial distribution of coastal wetlands is greatly affected by groundwater level and ocean tide. Thus reasonable protection of the region is of importance for protection of both the seawater and groundwater qualities.
