Ecological engineering approaches to restoring the aquatic biological community of an urban pond ecosystem and its effects on water quality ‑ a case study of the urban Xixi National Wetland Park in China

There is a global increase in urbanization, which contributes to the loss and fragmentation of urban wetland pond habitats. Urban ponds have an important role ecology areas, as they provide essential habitats for aquatic species. The objective this study demonstrate ecological engineering approaches restoring biological communities ecosystem, can be used achieve water purification such ecosystems globally. general approach first cleaning out then systematically applying different treatments plants fish was designed implemented field. We three replicated per treatment determine best option based on assessment quality indicators. main findings were follows: combination animals performance; furthermore, macrobenthos, Bellamya purificata , indicator species monitoring dominant local ecosystem. In conclusion, maintaining diversity over trophic levels performance ecosystems.
