With the rapid development of economy in China recently, river ecological problems have become severer, which leads to river ecological management and restoration to become a hot issue. In 2009, EU restoration engineering technology for small water body was introduced to repair several city rivers in Beijing. We selected Huaijiu River in Beijing as an example and conducted 5-year dynamic monitoring experiment from 2010 to 2014, aiming to study the application effects of this EU technology in China. The monitoring experiment includes river hydrology and topography, river water quality and species diversity. River hydrology and topography investigation was conducted once a year while river water quality survey selected 12 survey samples in July each year by applying field observation method. Species diversity research was conducted in July once a year using the electric fishing method, plankton net method, sample method, etc. The results show that the hydrology and topography of Huaijiu River have gradually improved after construction, indicating that restoration engineering technology for small water body plays a positive role in river hydrology and topography recovery. Furthermore, it turns out that river water quality continues to improve within five years in aspects of river turbidity, ammonia content and chemical oxygen demand. In addition, Huaijiu River has a steady rise in species diversity within five years and shows insignificant changes in diversity between 2013 and 2014. This study concluded that restoration engineering technology for small water body has a positive impact on the river ecosystem and the restoration effect on the river ecosystem will become stable in five years since the launch of the restoration engineering.
