The rapid development of urbanization leads to drastic cuts in urban green space,the contradiction between the city center area of public green land and urban construction land becomes increasingly significant,and three-diensional city park construction with more outdoor leisure space has become increasingly important in the development of city. By taking the overpass park design at East Haiqu Road and South Lvzhou Road intersection in Rizhao as an example,on the basis of the analysis of the present situation of space environment,by using three-dimensional space greening design concept, combining urban park and urban overpasses, the paper builds the city bus multifunctional vertical gardens to alleviate traffic pressure and enrich the landscape of the city.%城市化进程飞快发展导致城市绿化空间急剧减少,城市中心区域公共绿化用地和城市建筑用地的矛盾日益显著,城市公园立体化建设因能释放较多的室外休闲场地而在城市发展中日趋重要.文章以以日照市海曲东路与绿舟南路交叉口立交桥公园设计为例,在对场地环境现状分析的基础上,运用三维立体化空间绿化设计理念,将城市公园与城市过街天桥相结合,进行空间布局和植物配置规划,从而营造多功能垂直的城市公共立交桥空中花园,缓解交通压力,丰富城市的景观.
