Landscape Design of Highway in Southwest Mountainous Area Based on Ecological Restoration——Take Wuxi-Zhenping Expressway as an example
There are many problems such as large bridge-tunnel ratio,large civil wound surface,poor visual perception and discontinuous landscape for expressways in southwest mountainous areas.Wuxi-Zhenping expressway are located through the mountains across the gully most of which are bridge and tunnel connection and tunnel group.According to the present situation along Wuxi-Zhenping expressway,a corresponding ecological restoration scheme is put forward according to the characteristics of middle zoning,tunnel,interchange and side slope.Methods such as natural restoration,artificial planting,eco-bag greening+spraying organic trees greening are used to meet the basic requirements of smooth and safe passage of vehicles.The greening method which is close to nature without strong artificial traces is used to alleviate the conflict between highway and environment,protect and restore the ecological nature of road area,and achieve the harmonious unity of natural landscape and reconstructed landscape.
