摘要
滨海新区是东亚至澳大利亚候鸟迁徙的驿站,面积广阔的湿地生态系统为该区域主要的自然生态背景,区内有河流、湖泊、滩涂和沼泽等湿地类型,为水禽提供了必要的栖息地和繁殖地。但由于人为不合理利用和自然的原因导致滨海新区湿地退化现象严重。主要表现为自然湿地大量丧失、湿地被蚕食、湿地水质污染严重、湿地结构改变导致生态功能丧失。在分析退化原因的基础上,提出了恢复的对策并重点提出了针对滨海新区湿地恢复的林草地+湿地生态恢复模式,为该区域的湿地恢复和环境保护提供支持。
Binhai New Area is the post station of migratory bird moving from East Asia to Australia. Broad wetland systems are main ecological background of this area and include five types which are river,lake,beach and swamp. Wetland provide habitat for water bird. They are severely degraded because of human activities and other natural causes. At the same time,the degradation of wetland function is also serious as decrease of natural wetland,pollution and structure changing. Based on the analysis of degradation reasons,some suggestions are put forward to protect wetland resources. At last,a wetland restoration model which is called forest-grass and wetland model is put forward to protect and restore the wetland system of Binhai Area.
