Analysis on Spatial Layout Model of Urban Road Green Landscape Based on Discrete Probability

Abstract

The development issues about urban road greening design are constantly emerging in modern urban road construction. Therefore, a model of spatial layout of urban road green landscape based on discrete probability was built. The relevant urban road data was collected and the corresponding three-dimensional model of urban road was built. On this basis, the spatial layout and characteristics of urban road were analyzed. According to the analysis results, the greening modes and configuration methods that met the humanistic characteristics were established reasonably. Moreover, the green landscape vegetation was selected in consideration of the growth potential, height and seasonal phase of plants. Then, the discrete probability was used to determine the initial planting location and planting density of vegetation. Finally, following the principle of macro control and micro coordination respectively, the spatial layout of urban road green landscape was achieved from the horizontal and vertical directions. Based on the evaluation for the spatial layout model, it is concluded that the comprehensive score of the designed model is improved by 4.3 points compared with the traditional model.
