Jilin Province Highway Slope Biological Protection And Landscape Design,

This text combines the physical geography situation in Jilin Province and project characteristic especially, protect technology and carry on research to the highway synthetically. Through the survey of slope current situation by the completed highway of Jilin Province ,have analysed the disease type of the slope and disease mechanism of the slope by road bed, have protected the form and carried on objective appraisal to the slope by Jilin; Is it protect mechanism and research , slope of landscape design to plant to launch, get out of choice principle of protecting species of slope, combine the climate of Jilin Province, soil characteristic, has described growing ability and ecological characteristic rightly of different bank protection plant, combine Jilin Province highway investigation and research to protect current situation, is it suit Jilin area plant species that plant protect to propose; And protect the division of zoning according to the slope by Jilin Province, carry on view optimization design to the side slope project which relied on the project.According to along the line concrete conditions , consult existing slope state, to along the line slope , especially cutting slope goes on the system, investigates in an all-round way, according to the superhighway opposite side slope steady, safe project demand, the need of combining all such respects as afforesting, landscape design of environmental protection,etc. is principles, go on to along the line some concrete highway section slope protect, afforest, beautify the optimization that is designed, have perfected sloping and protecting designing further.Use the afforestation of a lot of variety, bank protection plant along the line, include (1)Arbor : Son looses the camphor tree, Dandong Chinese juniper cypress, white poplar, hanging down elms; (2)Bush : False indigo, cloves, sea-buckthorn, silk wounded in action, torch tree, honeysuckle, shrub lespedeza, cover the ground cypress, forsythia, golden pheasant; (3)The herb: Small to preceded flower, alfalfa, white three leaf, meadow early-maturing standing grain, purple sheep cogongrass, have awn bromegrass, ice grass, lay down the wheatgrass; (4)Climb the rattan plant: Boston ivy, humid euphorbia, Chinese ivy, welcomes spring, the rose, Chinese wistaria; (5)The flowers: chrysanthemum, marigold, coreopsis,etcHave adopted different afforestation to dispose the form to afforest the varieties of trees to different positions, side slope of different rock quality, Bush+grass, Arbor + Bush, Arbor + Bush+grass, Bush +flowers, grass +flowers, Arbor + Bush +grass+fiowers; Take colored bush, domatic level lawn as the core, combine low arbor, Xu root flowers, liana and herbaceous flowers, so that the greenbelt of both sides of the highway reaches the multi-layer three-dimensional structure with straggly level, make sure that there are flowers in three seasons , green.
