Landscape architecture is a living green infrastructure, a space carrier and an important physical element for the construction of ecological civilization and beautiful China. Environmental protection, ecological city and construction of living environment will be a long-term strategic task in the rapid development of urbanization in our country. The landscape industry is facing huge development space and opportunities.
     Plants can create a beautiful and comfortable living environment for human beings, and more importantly, they can create an ecological environment suitable for human beings. In the context of current urbanization, industrialization and climate change, the ecological environment on which humans depend is getting worse, the urban heat island effect is becoming more and more obvious, and people are getting further and further away from nature. Protecting the environment, beautifying the environment, and ecological restoration have become the trend of the times. Protecting plants and biodiversity, and insisting on sustainable development can ultimately save humanity. The application and management of landscape plants mainly involve the classification of landscape plants, configuration of landscaping, planning and design, planting and diversity protection, water and fertilizer management, shaping and pruning of garden plants, pest control and other post-maintenance. It is an important aspect of maintaining and improving the quality of landscape gardens and urban green spaces. In the process of compiling this book, we referred to books, periodicals and websites of landscape architecture, horticulture and cultivation, ecological environment and other aspects at home and abroad, and hereby give thanks to the authors above as well.
     We put a lot of effort into compiling this book, but due to the wide range of landscape plants and the limits of editor's experience, it is inevitable that there are mistakes or omissions in the book. Readers are welcome to criticize and correct them.

China’s rapid economic development, followed by the pursuit of improving the standard of basic living, including transportation. The development of economy is bound to improve the requirements of transportation. The technical core of BIM is rich in engineering information. At each stage, the owner (construction party), design, construction, operation and other relevant participants can exchange information and work together based on BIM model, effectively improving work efficiency, saving resource investment and reducing cost loss, so as to achieve the overall goal of sustainable development of construction industry. Compared with general public buildings, urban rail transit projects have higher social attention and greater social responsibility for the construction and operation parties, so it is more necessary to pay attention to the improvement of construction and operation level. Especially with the rapid development of domestic urban rail transit construction in recent years, a certain number of new lines are put into operation every year, no matter in design, construction, construction and operation management, there is a shortage of access resources, especially for experienced managers. How to improve “efficiency” under the premise of ensuring the construction period, quality and safety is a major problem to be solved urgently. In contrast, urban rail transit engineering has many engineering characteristics or difficulties, such as large scale, many specialties, small space, long construction period, tight equipment installation and commissioning time, high requirements for operation and management level. In this context, the application of BIM Technology can more reflect its great application value.
