Study On Plant Landscape Evaluation Research Of Street Garden In Luoyang City

With the accelerating urbanization process and the destruction of the urban environment,urban residents are increasingly eager to improve the urban environment and to rest and enjoy the natural plant landscape environment.At present,urban green space landscape construction has been valued because of its important role in improving urban living quality and improving urban living environment.As an important part of the urban green space,the Street garden is characterized by its wide distribution and small area.It forms a plant landscape with a pinch of needles,which can conveniently and efficiently provide various services to the public and create a beautiful and comfortable environment.Therefore,it is of great theoretical and practical significance to study the plant landscape evaluation of Street garden.In this study,the plant landscape of 15 Street gardens in Luoyang City was investigated and studied.The plant landscape status and plant species were analyzed,and the noise reduction effect of Street gardens was monitored under the condition of high and low-level noise.At the same time,the noise reduction function of Street gardens was taken as one of the landscape evaluation factors,Combining with other landscape evaluation factors.The method of analytic hierarchy process was used to construct the comprehensive evaluation model of the plant landscape of Street gardens,and evaluates the plant landscape of Street gardens.The results show that:(1)There are33 families,54 genera and 56 species of plants in the surveyed sample land,among which woody plants are the most widely used,most of which are mainly foliage plants,and the plant landscape is mainly concentrated in spring,summer and autumn,lacking the construction of winter plant landscape.(2)The richer the plant landscape layers,the better the noise reduction effect;Compared with low decibel noise state,high decibel noise state of the plant noise reduction effect is significant.(3)The comprehensive evaluation results of plant landscape showed that among the 15 sample plots surveyed,there were 3 class I plant landscapes,accounting for 20.00% of the total,9 class II plant landscapes,accounting for 60.00% of the total,2 class III plant landscapes,accounting for 13.00% of the total,and only 1 class IV plant landscapes,accounting for 7.00% of the total.
