Quality Evaluation of Green Space Structure of Dashushan National Forest Park in Hefei City Based on SBE-MATLAB Method
Taking Dashushan National Forest Park of Hefei City as the research object,three typical green spaces were selected,including general green space,waterfront landscape green space,and man-made hard landscape green space such as buildings,sketches and roads,and field photos of three kinds of green spaces were collected.SBE(Structure Based Evaluation)landscape evaluation meth-od was used to evaluate and score it,and the"multivariate quantitative model"function in Matlab software was used to build the corresponding landscape structure quality model of the three types of green spaces in Hefei Dashushan National Forest Park,so as to provide reference suggestions for the park landscape optimization in the later stage.Results show:In the general green space,the contribution of color quantity to the beauty degree of the general green space in forest park was the largest,reaching 28.5％,and the contribution rate of other landscape elements was ranked as follows:Landscape naturalness＞green visibility＞canopy density＞tree profile＞tree species composition number.In the waterfront landscape green space,the overall coordination contributed the most to the landscape beauty,reaching 25.5％.The contribution rate of other landscape elements was ranked as follows:vegetation coverage rate＞landscape nature degree＞laminate structure＞tree planting method＞revegetating type＞water type.Among the green space surrounding the artificial hard landscape,the natural degree of the landscape has the largest contribution to the beauty degree of the green space around the artificial hard landscape,reaching 24.6％.The contribution rate of other landscape elements is ranked as follows:tree planting method＞composition of life type＞artificial landscape style＞spatial structure.Based on the analysis results of the three types of green landscape beauty models,it is suggested that the park landscape optimization in the later stage should pay attention to increasing the number of plant colors,creating a natural community structure with the combination of horizontal and vertical structures of different color plants,paying attention to coordinating the proportional relationship between plants and water space,and using the combination and collocation of different life types of plants.To construct green open space suitable for carrying out activities in the forest to meet the needs of leisure and recreation.
