Roof garden design Many factors need to be considered, such as building structure, water conservancy facilities, soil conditions, plant species, etc., and how to coordinate the roof garden with the surrounding environment. Therefore, the following points should be noted in the design and layout process:

Structural design: The design of the roof garden must conform to the structural characteristics of the building. Therefore, the strength and bearing capacity of the building, as well as the distribution, drainage and ventilation of the garden must be considered in the design process.

Environment coordination: when designing the roof garden into the building, it needs to coordinate it with the surrounding environment, such as connecting the garden with the surrounding green belt, roads, etc., and at the same time cooperating with the appropriate architectural style to make the garden more natural and enhance the affinity between people and the natural environment.

Selection of plants: The plant selection of roof garden should take the growth environment and safety of plants as the main factors to ensure the ecological environment of the garden. Plants suitable for growing in harsh environments, such as varieties with drought resistance, cold resistance, wind resistance and other characteristics, should be selected, and chemical fertilizers, pesticides and other materials harmful to the environment should be avoided.

Water conservancy facilities: The water conservancy facilities of the roof garden are one of the keys to success. A well-designed water conservancy system can ensure the circulation and utilization of water and reduce the discharge of wastewater. In the garden, it is not only necessary to have natural waterscapes such as fountains and streams, but also to establish a rainwater utilization system combined with ecological soil technology to ensure the normal growth of plants.

Greening layout: in the process of roof garden layout, reasonable planning should be carried out in combination with actual needs. The garden should be divided into several functional areas, such as recreation, sightseeing, planting, etc. Different plants and decorative materials should be arranged according to different functional areas to enhance the practicability and beauty of the garden.
