Development of Wetland System for Irrigation Management and Its Multifaceted Practices, a Case Study of Constructed Wetlands

ABSTRACT

Located in Tengliaukeng Ravine catchment river basin, the Zhanghe Wetland (ZW) represents the constructed wetlands (CWs). Its function includes wastewater treatment, ecological conservation, irrigation, environmental education, flood regulation and climate change adaptation. Moreover, it collaborates with nearby schools to integrate ecological curricula into their educational programmes. Students' appreciation for wetland ecosystems is enhanced. This study involved the sampling and analysis of water quality in both inflow and outflow of the wetlands. The primary objective of this project was to conduct long‐term sampling and testing of water quality in CW sites. Specifically, the focus was on inflow points, treatment units within the CWs and outflow water quality. The results of the survey provided the valuable data and played a vital role in wetland stewardship partnership. The survey was organized according to the distinct requirements of different species within each zone of the ZW. Its emphasis was on terrestrial ecology, covering aspects such as flora, avifauna, amphibians and reptiles, butterflies and Odonata. The calculated pollution reduction results demonstrated improvements in the outflow concentrations of ammonia nitrogen. The results of water quality analysis and the pollution removal effects of wetland water purification are presented, respectively.
