摘 要:受气候变化,河流断流,海洋灾害,污染,围垦,海水入侵,盐业、养殖业的发展,过度捕捞,过度开发利用水资源,不合理的工程建设等因素的影响 ,近30多年来莱州湾南岸滨海湿地呈现明显的退化趋势。如自然湿地面积减小、植被退化、人工湿地面积扩大、湿地生物多样性受损、渔业资源衰退等。作者针对导致湿地退化的原因提出了减轻海洋灾害、合理发展盐业和渔业生产、严格控制污染物入海、恢复湿地水文条件以满足湿地生态需水。Due to global climate change,decreasing river flows,marine disasters,expansion of the salt and fishing industries,seawater intrusion and increasing pollution,the coastal wetlands of the Southern Laizhou Bay have degraded obviously over the last30years. While natural wetlands are diminishing in size and their vegetation is degrading,artificial wetlands are extending and biodiversity and fishery resources are damaged. This paper proposes some primary methods for restoration of degraded coastal wetlands.Through engineering and eˉcological solutions impact of natural disasters can be mitigated.Furthermore,controls on the scale of the salt industry and mariculture and subsequent reductions in pollution,plus economical use of the regional water resources and input of water from other drainage basins will restore the hydrological condition and create an artificial reed marsh.
