Landscape soil engineering is an interdisciplinary application of soil science, landscape architecture, materials science, and other disciplines. It is an essential component of landscape engineering, including the planning and design, budgeting, construction, supervision, completion acceptance, and maintenance management of landscape engineering. The quality of landscape soil engineering directly affects the landscape effect of plants and the cost of later maintenance management. The article expounds on the background and concept of garden soil engineering and its critical role in garden engineering by studying the concepts and practices of garden soil engineering at home and abroad. It provides scienti c reference and technical support for the construction of urban landscaping in the new era.
