城市道路两翼植物景观三维图像优化设计仿真

City Road Plant Landscape Wing 3D Image Simulation Optimization Design

对城市道路两翼植物景观三维图像进行合理设计,可以改善城市环境。进行道路两翼植物景观三维图像设计时,需要建立在彩色植物的色彩季变化规律和彩色植物的生理生态特性的基础上,但是传统方法通过获取道路两翼植物配置特征,设定城市道路两翼植物彩化的立体指标,并对道路两翼植物景观进行三维图像设计,但没有考虑彩色植物的色彩季变化规律和彩色植物的生理生态特性,存在景观三维图像设计局限性大的问题。提出了一种基于层次分析的城市道路两翼植物景观三维图像优化设计模型。首先以突出城市特色和生态性为原则得到景观中合理配置彩色植物的基本条件,依从景观主题需要,获取对道路两翼植物彩化景观造景元素,得到彩色植物的色彩季变化规律,给出彩色植物的生理生态特性,并提出三维彩量概念,计算出城市道路两翼植物彩化景观的三维彩量,依据三维彩量对城市道路两翼植物景观三维图像进行优化设计。仿真结果表明,改进方法为城市道路两翼植物彩化景观设计提供理论依据。

It can improve the city environment to design the 3D image of plants landscape on both city roadsides. The 3D image design needs to be built based on color seasonal variation rule and physiological ecology feature of color plants. In this paper, we proposed an optimization design method for 3D image of plant landscape of both city road- sides based on analytical hierarchy process. Firstly, we obtained the basic conditions of reasonable allocation of color plants using highlighting the urban feature and ecology as principle. Then we gained the landscaping elements of plants coloring landscape and obtained the color seasonal variation rule according to the need of landscape theme. The physiological ecology feature of color plants was given out and the 3D color quantity was proposed. Finally, we worked out the 3D color quantity of plants coloring landscape. According to the 3D color quantity, we made optimization design to 3D image of plant landscape on both city roadsides. The simulation results show that the modified method can provide the theoretical basis for design of plants coloring landscape on both city roadsides.
