Description

Multifunctional combined landscape structure unit and landscape belt for rainwater harvesting and utilization

technical field

The invention belongs to the technical field of greening and landscape, and in particular relates to a multifunctional combined landscape structure unit and landscape belt for collecting and utilizing rainwater.

Background technique

In the context of sponge city construction, pilot cities across the country have adopted measures such as infiltration, stagnation, storage, purification, utilization, and drainage of rainwater to improve rainwater management capabilities to build urban ecosystems and avoid rainstorm disasters. These mainstream technologies are mainly used in municipal engineering in cities, mostly in subgrade and underground treatment, and are in a hidden state. In terms of vertical design, it often focuses on the underground part, ignoring the possibility of development in the air. In addition, the existing technical measures still lack public participation, pay little attention to the public's space needs and subjective initiative, and have relatively low requirements for landscaping effects. If people’s subjective initiative can be better played, starting from the perspective of landscape science, it will not only meet the construction requirements of the sponge city, benefit the urban ecological environment, but also create a space for public activities and increase public participation, which may become a sponge city. It provides new ideas and methods of construction.
