The openness of the system can be free of groundwater, and avoid the water discharge due to increased pressure caused by the slope unstability problem, This system in addition to the stable slope have certain contribution, also can inhibit the weathering and eroding of slope suffer further, and characteristics of slope no special requirements, no damage and change the original landscape morphology and slope vegetation grows conditions, the future for subsequent or open features are needed and implementation of artificial slope greening retained the necessary conditions, green plants in the open space to grow on freedom, plant roots and solid soil slope protection system, thus inhibiting the massing of slope destruction and soil erosion physiognomy, turn to protect slope vegetation, and realize the optimal slope protection and environmental protection purposes.
