Study On Slope Ecology Protection And Plants Landscape Of Ning-Chang And Ning-Hang Expressway

The dissertation focuses on the slope ecological protection and landscape research based on Ning-Chang and Ning-Hang Expressway, selected representative slopes, set up 18 observation points to research 8 kinds of eco-protection of linked network hydroseeding(LNH), spray seeding(SS), grass-package technique(GPT), bamboo planting(BP), grass-stick technique(GST), planting grass protection(PGP), liana protection(LP), geogrid grille(GG).The following is the main research aspects:(1)Through investigation into the configuration and the growth of vegetation of the observation point, compared the plants landscape effects of the slope. From the dynamic changes of plants to start, author analyzed plant growth rates, cover-time dynamic change, and benefits of slope eco-protection, ecological protection and landscape effect of linked network hydroseeding, spray seeding, geogrid grille, grass-stick technique, grass-package technique are better in green pre-planting, bamboo planting, grass-stick technique, spray seeding, liana protection are better in late stage.(2)Through constructed AHP evaluation matrix, evaluated the integrated quality of various forms of slope eco-protection vegetation restoration, from the four of the ecology benefits, landscape benefits, and ecological benefits, social benefits, 18 observation points were sorted and analyzed. From good to bad, integrated quality of slope ecology protection vegetation restoration is bamboo planting(06,07), spray seeding(15), geogrid grille(13), linked network hydroseeding(18), geogrid grille(14), spray seeding(01), grass-stick technique(09), linked network hydroseeding(12), liana protection, linked network hydroseeding(17), grass-package technique, planting grass protection(11), grass-stick technique(02), planting grass protection(10), bamboo planting(16), linked network hydroseeding(08), linked network hydroseeding(05).(3)Taking Ning-Hang ExpresswayПas an example, the author discussed design program of slop landscape, analyzed the slope status, design idea and plant configuration mode, and put forward optimized the measures and proposals and further enhanced the slope ecological design.
