Abstract
In the present experiment, we took a section of Liaohe River in east of Shuangan bridge Yingzhou District, Tieling as an example to study ecological slope protection technique of riverbank in an agricultural catchment. In order to assess the potential of the slope protection project, the length of new taproot, height of new branches, and base diameter of shoot were determined. The results showed that the pioneer species such as Salix suchowensis and Amorpha fruticosa are growing very well with strong root system and flourished branches, which can help control soil erosion effectively. Furthermore, the growth indexes of Salix suchowensis were higher than those of Amorpha fruticosa after five months growing. Along with the riverbank being reinforced by soil bioengineering technique, native plants have been in rapid restoration and biodiversity increases.
