Abstract

With the rapid urban development and population growth, urban environment experiences increased pressure resulting in worse ecological problems. As a transitional ecosystem, urban wetlands have important ecological functions such as regulation, buffering and filtration in the city. Therefore, construction of urban wetland parks has important ecological functions to the health of ecosystems, such as water storage, flood control, drought prevention, control of water and soil, climate regulation, and increasing species diversity. The construction of an urban wetland park not only provides a place for science education, rest, and entertainment to public, but also protects the existing wetland and improves the quality of urban environment. It’s also important to understand the performance of the wetland system. Nevertheless, over the past years, there’s no evaluation system has been established. This paper developed a comprehensive evaluation system and determined the weight value for each evaluation index by questionnaires and AHP software. Furthermore, this paper took Harbin Qunli National Wetland as an example to conduct a practical evaluation of its wetland performance. The data to support the evaluation indexes were obtained through a combination of literature review, field investigation, lab test and mathematical modeling methodologies. The results showed that ecology was as important as environment in the wetland evaluation system, and water quality, soil environment, water resources and species diversity had the highest proportion among the small indicators. Harbin qunli national wetland park is in good condition.
