The erosion of riverbank and the disappearance of riparian buffering strips are among the concerns in river ecosystem.In this study

we took an airport town in Pudong new district

Shanghai as an example to study the practice and its ecological effect on plant slope protection techniques of streams

which could provide an effective means for the slope stabilization and site restoration of stream bank.We investigated the application of three kinds of plant slope protection techniques

including all-series vegetated protection

soil bioengineering

and combined biostabilization at different sites of ecological river.The plant slope protection project at the demonstration site was conducted continuous ecological monitoring from 2004 to 2006 after the reconstruction was finished.The results indicated that the pioneer species are growing very well with strong root system and flourished branches

which help control soil erosion effectively.As an indicator of soil anti-erodibility

the soil strength and compaction of the subsurface soil with a mean deepness of 15cm are going up and much more than the un-covered control slopes

which made the soil erosion mitigated sharply and the structural stability of riverbanks enhanced.Along with the riverbank being reinforced

the habitats of the riparian zone are under self-improvement and native plants have been in rapid restoration.The ecological stability of eco-riverbanks is being enhanced duo to a high species diversity and complex plant community structure.It was concluded that the approach could be widely applied in ecological restoration and riverbank slope stability of all kind of slopes in China.
