The Landscape Transformation Of Shenzhen Road In Chengdu City Based On The Concept Of Ecological Engineering Law

With the rapid development of urbanization in China,road construction is also spreading across the country.To make up for the environmental damage caused by road construction,road greening required integration with road construction.Due to the different conditions of road greenbelts,the conditions are different from other green Spaces.It has the characteristics of "more varied terrain,steep slope and adjacent natural environment".Therefore,we should carry out targeted afforestation exploration.Ecological engineering is a kind of special construction idea and technological measure applied in all kinds of projects,it's concept is "the integration of geotechnical engineering benefits and ecological environmental benefits",it's characterized by"using stone,wood,plant or other natural materials as raw materials for geoengineering",it makes "geotechnical structure and environmental to integration,and can provide plant and animal growth,showing the natural beauty of the ornamental effect".The ecological engineering method is widely used in "river and stream control,road engineering,river-lake reservoir revetment project",among them,the application of the river stream is mainly used,it is still in the experimental application stage in road engineering.The method of landscape construction of road slope is put forward,namely integral construction method and geotechnique.This study is devoted to the application of ecological engineering method in road belt greening engineering.In the research and analysis of the theory development and application of ecological engineering law and the study of typical ecological engineering practice cases at home and abroad,the application of ecological engineering method in road landscape construction is explored theoretically,This paper puts forward the core of the concept of road slope landscape construction based on ecological engineering method,purpose and value,Five principles of ecological engineering of road slope are put forward,the optimal method,resource recovery,wholeness,minimum damage recovery and comfort.Terrain landscape to high and steep,civil landscape integration are put forward for slope landscape construction.Taking Shenzhen road of Chengdu as the design case,according to the hilly terrain and the site characteristics of the cutting slope.This paper designs the ecological works such as "gabion cage ecological retaining wall,ladder grating guardrail,planting block retaining wall,planting bag slope protection,slope depression",which adjust the slope topography in the green belt of road.Finally,all kinds of terrain can better meet the requirements of plant growth,meanwhile,the geotechnical structure is integrated into the surrounding environment,also make the effect of natural beauty become true.
