| With the improvement of our countries’ road system,a large number slope engineering appears by the widen and upgrade construction of the original roads.Since people’s requirements of ecological and landscape demands is raising,slope engineering is no longer a simple engineering protection,but a comprehensive slope structure with ecological function, landscape function and cultural function.This paper emphasizes the importance of slope ecological restoration,and distinguish the priorities and design methods with traditional planting.Then respectively expounds the classification of the slope, the principle and process of ecological restoration,and put forward the basic theories of highway landscape construction,the concept of green way and ecological theory of slope recovery.By comparing the construction process,applicable areas and main technical points,introduced the ecological recovery technology of slope protection and planting design used in northern area,Finally comes to the advantages of the net external soil spray seeding technique in slope ecological protection engineering technologies.The case analysis took Hemu scenic spot highway in Xinjiang Kanas area as the main object of study,cases in Urumqi Economic and Technological Development Zone to be added,through field investigation and data analysis of the design mode of road slope characteristics,ecological restoration,summarized and analyzed the characteristics of the cases in three aspects:biological design, engineering design and landscape design.Come to the detailed analysis of the slope conditions in project area, analyzed the necessity of ecological restoration,then summarized three key technical principles of restoration design:plant selection should be adjust to the local conditions;engineering technique with small environment influence;merging with nature environment coordination.External soil spray seeding technique is suggested to be the main Engineering design method.Through the quadrat investigation, nursery cultivation, and combined with the natural succession,it comes to suitable planting design.In landscape design part puts forward the design scheme of the ecological, environmental friendly,and regional characteristics of road landscape. |
