At present, the greening pattern in north China is developing from monotonous regular pattern to the multivariate combined pattern. The greening structure is more hierarchical and diverse. Due to geological and climatic reasons, the barren hills and mountains in north China region have an obvious negative impact on the urban landscape. Therefore, soil amelioration has become the guarantee for the survival of trees, as well as plays a fundamental role in the construction of urban green space and landscape in the north. Most of the researches on soil amelioration in China tend to be used single means, few of them use a combinations of various soil improvement technology to improve soil structure and physical and chemical properties. Through the research and practice of soil improvement technology in Rizhao west passenger station, aiming at the problems of poor permeability and breathability, high hardness and nutrient deficiency of soil, a variety of soil improvement technology combinations, such as multi-layer composite structure community, soil reconstruction (new technology of soil physical and chemical properties and soil reconstruction), soil infiltration and drainage system, are adopted to improve the square landscape of Rizhao west passenger station, shaping a modern station square landscape with a sense of rhythm and ceremony, to create a “city card” of Rizhao.
