Research On Aquatic Plants Landscape Aesthetic Evaluation Of The Haizhu Wetland Park By SBE Method

The urban wetland is an important ecological core of the city,and aquatic plants landscape is the main natural landscape of a wetland area.How to plan a landscape of the wetland with aquatic plants landscape is an important part of the wetland park landscape design.Waterscape should not only meet the landscape requirement,but also be affirmed by tourists,The application of the performance evaluation method of waterscape is an important part in the construction of Wetland Park landscape.In this paper,taking the green heart lake area and Huaxi scenic spot of Haizhu Wetland as an example,by using SBE method combining with the investigation questionnaire,the aquatic plants landscape in Haizhu wetland was evaluated.and then selects the vertical structure of aquatic plant with high scenic spot.Analysis of differences in the aquatic plant landscape in the waterscape landscape factors and different evaluation subjects of landscape evaluation,set up the data model of aquatic plant landscape,and then to analyze the defects of aquatic plants in Haizhu wetland landscape is and the corresponding improvement measures,It will provide references for further construction of Haizhu wetland in the future.The main results are as follows:(1)From October to December in 2016,I conducted a questionnaire survey on the landscape of the water landscape in the scenic area of the green heart lake and the surrounding Huaxi scenic spot,and 40 questionnaires were obtained.34 valid questionnaires were obtained and 6 were finally analyzed Participants raised questions about the seasonal nature of the plant,eight participants presented a single color issue,seven participants suggested that the lack of dynamic vitality in the landscape,three participants referred to the phenomenon of vegetation within the landscape.These data indicate that the largest landscape problem exists in the landscape of the aquatic plants in Haizhu wetland,which is that the artificial traces are too heavy.(2)According to the statistical analysis found that the SBE value of arbor shrub herb type plant structure SBE average value is 0.117,the structure of the SBE tree and shrub plant average value was-0.213,Joe grass type plant structure SBE average value is-0.187,shrub and grass plant structure of the SBE standard value is 0.093,the arbor shrub herb type structure numerical plant that is the highest,most participants welcome vertical plant community.SBE standard value of 1.09 of the 58 plots,is the highest value in all plots,the vertical structure of the plant is the ratio of shore grass and shrub plant landscape community of 3:3:1,Thalia dealbata+ Cordyline fruticosa + Strelitzia reginae +Plumeria rubra+Camptotheca acuminatacan,increase the water plant community in the species in the area to increase the beauty of the landscape.(3)The analysis of findings in different areas of the water landscape,waterfront plant landscape of the SBE standard value is 0.085,waterfront plant landscape SBE standard value is-0.02,the water plant landscape beauty standard value is-0.001,which shows little difference between different participants,the ornamental area is not much affected.(4)Analysis of various types of landscape factors through the SPSS display of the wild plant landscape factors in the process of factor sig value reached 0.006,the spatial structure factor sig value is 0.026,the planting mode of the sig value is 0.068,the layer structure of the sig value is 0.059,the number of species is negative correlation factor,the sig value is 0.062 that is,the sig value of significant meaning,but the sig said the smaller the impact factor is more significant,so the results show that it is the greatest feeling wild plants factor affecting the participants.Wetland plant landscape visual features(5)After analyzing the landscape factors,the landscape factors that influence the landscape of the water landscape of Haizhu wetland are number of tree species(X1),spatial structure(X2),plant planting method(X3),lamellar structure(X4),wild degree(X5)and beauty value Y,combined with their own standard coefficients,the data model is: Y =-1.2-0.134X1 + 0.092 X2 + 0.047 X3 + 0.083 X4 + 0.13 X5.According to the model,it can be seen that the higher the number of species,the lower the beauty value,the lower the beauty value,the higher the spatial structure and the higher the beauty value from the spatial structure.From the plant planting method,When the plant is planted,such as planting,planting,planting mode,the higher the beauty degree;from the lamellar structure,the landscape structure characteristics of the more obvious,the higher the landscape beauty value;from the rust factor,The more ecological features of the landscape landscape,the higher the beauty value.(6)In view of the serious problems such as severe artificial traces,plant level monotonousness,seasonal ecology and lack of dynamic landscape in the landscape of Haizhu wetland,combined with field investigation and data analysis,a series of optimization suggestions were put forward: the introduction of native tree species to weaken the wetland The artificial landscape of the landscape;actively create a space-changing plant community to enrich the plant space structure;increase the autumn and winter plant,so that the four seasons are King King reward;control the number of foreign plants,increase the introduction of bird species,the introduction of dynamic landscape The whole landscape of the plant space is lively.
