摘　　要：针对海河流域滨海湿地面临的日渐严重的天然湿地萎缩、生态环境恶化等问题,选择七里海、南大港、北大港等典型滨海湿地,基于遥感解译和灰色关联度方法,对其主要的生境问题进行诊断,分析其退化的主要原因,为湿地生态恢复提供技术支持。通过分析发现,各湿地面积呈减小趋势,尤其是芦苇湿地面积明显减少,多转化为建设用地,人为因素主导了北大港湿地退化,而自然因素和人为因素共同加速了七里海、南大港湿地退化。This study is aimed at the coastal wetlands in Haihe River Basin,which is facing increasingly severe natural wetland atrophy,ecological deterioration and other issues. Typical coastal wetlands,such as Qilihai,Nandagang and Beidagang,were selected to diagnose the main habitat problems based on remote sensing interpretation and grey relational degree. The main causes of wetland degradation were analyzed to provide technical support for wetland ecological restoration.According to the analysis,the area of each wetland tends to decrease,especially the area of reed wetland,which is mostly converted into construction land. The degradation of wetland in Beidagang is dominated by human factors,while the degradation of wetland in Qilihai and Nandagang is accelerated by both natural and human factors.
