The Ecological Floating Bed Landscape Construction Model Research In Jin Jia Qiao Section Of The Shanli River, Shenyang

In the process of rapid urbanization,due to the serious lagging of urban infrastructureconstruction,some rivers in the city have become the drainage channels of domestic sewage and industrial waste water,so that the water environment problem is becoming more andmore serious,and the black and smelly phenomenon of water is serious,which seriously affects the quality of life of the residents.However,the hard hardiness of river banks has greatly increased the difficulty of purifying aquatic plants on the banks of the river,and the ecological floating bed has solved this problem well in the treatment of sewage.In the study of ecological floating bed,from the initial ecological first,the landscape effect has gradually been paid attention to.People have seen the role of ecological floating bed in the landscape,but there is no one to evaluate the ecological floating bed configuration landscape.How to build an ecological floating bed with both ecological benefits and good landscape effects has become the focus of our research.In this paper,through the analysis of the research achievements and progress in the related fields,15 kinds of aquatic macrophytes used in the water landscape of the main city ofShenyang are investigated,which belong to 22 species,belonging to 13 families and 16genera.5 kinds of aquatic plants?shallot,Zizania,Acorus,rhizome,Ci Gu?were selected for plant configuration design,and 4 kinds of ecological floating bed plant configuration models?P8,P16,P14,P5?were obtained.In the scope of the study,the ecological floating bed was designed according to the coverage area?25%-30%?needed by the ecological floating bed.After screening the stability and formal beauty rule,4 kinds of floating beds?rectangle,square,shuttle and enclosure?were finally obtained.4 kinds of floating bed plant allocation modelswere selected and 4 different shapes of floating bed carrier 22 were combined.16 ecological floating bed configuration models were obtained as evaluation samples.The quantitativeevaluation system was established by using the landscape aesthetics principle.Thepsychological evaluation of different ecological floating bed configuration patterns wascarried out to get a better ecological landscape effect.The floating bed configuration modeand the main factors that affect the effect of the ecological floating bed landscape.The results of the study show that:?1?the SD method was used to analyze the results of 4 different shapes of ecological floating beds.The results of the visual effects were:the enclosed floating bed?0.49?>the rectangular floating bed?0.33?>the shuttle shaped floating bed?0.31?>the square floating bed?0.24?.?2?through the analysis and analysis of the survey data,the landscape effects of 4 plantconfiguration patterns were classified as:Central 4 plant configuration models?0.48?>strip plant configuration model?0.46?>mosaic plant configuration model?0.44?>central type plant configuration model?-0.02?.?3?The rank of landscape effect by the evaluated and analyzed of 16 samples were that:D-4?0.65?>D-2?0.61?>D-1?0.51?>A-4?0.47?>A-1?0.47?>B-1?0.44?>C-4?0.43?>C-1?0.41?>A-2?0.39?>B-4?0.39?>C-2?0.38?>B-2?0.37?>D-3?0.18?>C-3?0.02?>A-3?-0.02?>B-3?-0.25?.?4?The visual quality evaluation model of the ecological floating bed landscape of yamanhe river was constructed by regression analysis:Ys=-0.189+0.205X₇+0.191X₅+0.104X₁₀+0.133X₁₄+0.115X₁₃+0.123X₁₁+0.124X₃+0.062X₁₂.(X₇ represents pleasure,X₅ represents overall beauty,X₁₀ represents color collocation,X₁₄represents plant ornamental characteristics,X₁₃3 represents plant scale coordination,X₁₁representative hierarchy,X₃ represents attraction,X₁₂2 represents natural).To remove the overall subjective landscape evaluation factor of the ecological floating bed,the effect of the ecological floating bed landscape effect is the plant ornamental characteristics,the sense of hierarchy,the coordination of plant scale,and the rationality of color matching.
