以广州海珠国家湿地公园为研究对象，以环境、生物因子为评价指标，分析建园后湿地生态环境的动态变化。结果表明，湿地公园建成后，水体COD、NH3-N含量逐渐降低趋于平稳，而 DO含量升高，空气中 PM10、PM2.5、CO含量下降，表明区域内水、空气质量总体向好；鸟的种类从77种（2013年）增至177种（2018年），增长129.87%，且吸引了更多珍稀鸟类、鱼类、爬行类、兽类栖息；湿地内乔木、灌木、草本、藤本组成稳定，乡土植物优势突出。

Taking Haizhu National Wetland Park in Guangzhou as the research object,and taking environmental and biological factors as the evaluation indicators,the dynamic changes of wetland ecological environment after the completion of the park were analyzed.The results showed that after the park was built,the content of COD and NH3-N in the water,and the content of PM10,PM2.5 and CO in the air decreased and stabilized,while the content of DO increased,indicating that the quality of water and air in the region is better.The number of bird species increased from 77 (in 2013) to 177 (in 2018),with an increase of 129.87%,and attracted more rare birds,fish,reptiles and beasts to live in.In addition,the composition of trees,shrubs,herbs and vines in the wetland was stable,and local plants were dominant.
