This paper investigated the main rivers in the wetland area of the Yellow River delta, and compared the hydrological water quality in 2002 and 2017. River section monitoring results showed that water quality of seven rivers in the Yellow River delta were all polluted, the Shenxian ditch, Xiaoqing river, Zi river and Guangli river were heavily polluted, but as time went on, the water quality improved. The environmental pollution of the Yellow River delta has a great influence on the composition and stability of wetland ecological environment and ecosystem, which is mainly manifested in the destruction of habitat caused by environmental pollution, biodiversity destruction caused by habitat destruction or contamination, ecological damage and loss of function caused by comprehensive factors such as habitat and biodiversity destruction.%通过对黄河三角洲湿地地区主要河流的调查,并对其2002 年和2017 年的水文水质进行监测比较.河流断面监测结果表明,黄河三角洲上7 条河流水质全部遭受污染,其中神仙沟、小清河、淄河、广利河达严重污染,但随着时间的推进,水质日益好转.黄河三角洲环境污染对湿地生态环境和生态系统组成及稳定性造成了重大影响,主要表现在: 因环境污染而导致生境的破坏;因生境破坏或污染物毒害而引起生物多样性破坏;因生境、生物多样性破坏等综合因素引起的生态结构破坏及功能丧失.
