Research On Landscape Evaluation Of The Taiyuan Yingze Park By SBE Method

As an important place for leisure and entertainment,Yingze park of Taiyuan city has brought remarkable ecological and social benefits to the city construction.In order to further improve the landscape quality of the park,Yingze park was renovated in July 2017.There are few reports on whether the landscape quality has been improved after the renovation and what factors have affected the landscape of Yingze park specifically.Therefore,this paper adopts the evaluation method of public participation,namely the SBE evaluation method of beauty degree.According to the green space,the landscape of Yingze park is divided into three categories:common plant landscape,man-made hard landscape such as structures and roads,and waterfront plant landscape.The landscape quality before and after the transformation of the three categories is evaluated respectively.The main factors affecting the landscape of common plants,structures,roads and other man-made hard landscape and waterfront plant landscape were screened out,and the evaluation models were constructed for the main factors affecting the landscape quality.The main conclusions are as follows(1)The average landscape quality of general plant landscape was improved by 53.9%before and after transformation.The average landscape quality of artificial hard landscape was improved by 80%before and after reconstruction.The average landscape quality of waterfront plant landscape was improved by 56.7%before and after the reconstruction.After the reconstruction of Yingze park,the landscape quality was improved obviously and the reconstruction was successful(2)The factors that affect the beauty degree of general plant landscape are as follows:the smallest factor is the herbaceous coverage factor;the largest factor is the number of color species;other indicators,such as the height of tree layer,enclosed space form and color contrast,are in the middle.The prediction model of building common plant landscape with the remaining 5 elements is as followsSBE=0.57+0.17Ai+0.29A2+0.87A3+0.27Bi+0.33B2-0.77C1-0.53C2+0.52D1+0.31D2-0.19E1-0.14E2(2)The smallest factor is the line of sight center factor,the largest factor is canopy density,and the other factors,such as the overall coordination of other indicators,the occupancy of vegetation space,and buildings,affect the landscape quality in order to reduce.The prediction model for the construction of man-made hard landscapes such as structures and roads with the remaining 5 elements is as followsSBE=0.38+0.11 A1+0.42A2+0.5 1 A3-0.43B1-0.29B2+0.38C1+0.23D1+0.12D2+0.37D3+0.069D4-0.45E1-0.19E2(3)The smallest factor is the revetment factor,the largest factor is the color contrast,the other main indicators of plant morphology,sky proportion factors affect the landscape quality in order to reduce.The prediction model of waterfront landscape constructed with the remaining four elements is as followsSBE=0.69-1.38A1+0.04A2-0.61B1-0.37B2+0.46C1+0.28C2+0.85D1+0.33D2...
