摘要:以广州大观湿地公园为研究对象，在建立了综合指标评价体系的基础上，通过水质监测、问卷调研、植被样方调查等方法，对大观湿地公园的生态绩效和社会绩效进行评估，并为未来的湿地公园设计提供指导。评估结果显示：湿地公园初步达到了生态和社会效益兼顾的目标。公园内生境类型多样，植物种类达32科54属66种，Shannon-Wiener指数分析表明，草本植物多样性丰富，乔木层由于人工种植原因多样性较差。公园的串联式坑塘系统具有显著的污染物净化效果，可以明显降低汇流区的氮素含量，但其水质净化效果并未达到最大化。公园建成后吸引了大量周边居民的来访，整体满意度较高，但由于有外界污水持续混入上游坑塘，导致游客对上游坑塘水质的评价较差。在以上分析基础上，提出对未来的城市湿地公园设计的指导建议。



Abstract:This paper takes Guangzhou Daguan Wetland Park as the research object. Based on the establishment of a comprehensive index evaluation system, we evaluates whether the Daguan Wetland Park takes into account ecological and social benefits through water quality monitoring, questionnaire survey, and vegetation sample survey. This paper evaluates the ecological and social benefits of Daguan Wetland Park through water quality monitoring, questionnaire survey, vegetation quadrat survey and other methods, then the paper provides guidance for the future design of wetland parks. The assessment results show that the wetland park has initially achieved the goal of balancing ecological and social benefits. There are various habitat types in the park, and there are 32 families, 54 genera and 66 species plant species. The Shannon-wiener index analysis shows that the herb layer is rich in diversity, but the tree layer is poor in diversity due to artificial planting. The tandem ponds system has significant pollutant purification effect, which can significantly reduce the nitrogen content in the catchment area, but its water purification effect has not been maximized. The park has attracted a large number of visitors from nearby, and their overall satisfaction of the park were high. However, the tourists' evaluation of the water quality of the upper ponds was poor due to the continuous draining of external sewage. Based on the above analysis, this paper proposes guidance for the future design of urban wetland parks.
