A 'red line' was established, identifying an area requiring for ecological protection in Tianjin, China. Within the protected area of the red line area, the Qilihai wetland is an important ecotope with complex ecological functions, although the ecosystem is seriously disturbed due to anthropogenic activities in the surrounding areas. This study assesses the water quality status of the Qilihai wetlands to identify the pollution sources and potential improvements based on the ecological red line policy, to improve and protect the waters of the Qilihai wetlands. An indicator system was established to assess water quality status using single factor evaluation and a comprehensive evaluation method, supported by data from 2010 to 2013. Assessment results show that not all indicators met the requirement of the and that overall, waters in the Qilihai wetland were seriously polluted. Based on these findings we propose restrictions on all polluting anthropogenic activities in the red line area and implementation of restoration projects to improve water quality.
在中国天津划定了一条“红线”，确定了一个需要进行生态保护的区域。在红线区域的保护区内，七里海湿地是一个具有复杂生态功能的重要生态区域，尽管由于周边地区的人为活动，该生态系统受到了严重干扰。本研究基于生态红线政策评估七里海湿地的水质状况，以确定污染源和潜在的改善措施，从而改善和保护七里海湿地的水域。建立了一个指标体系，采用单因素评价和综合评价方法，利用2010年至2013年的数据来评估水质状况。评估结果表明，并非所有指标都符合要求，总体而言，七里海湿地的水域受到了严重污染。基于这些发现，我们建议对红线区域内所有污染性人为活动进行限制，并实施恢复项目以改善水质。
