Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。
