With the improvement of people's living standards, people's requirements for quality of life have also increased. In recent years, wall greening has gradually emerged in urban greening. Good landscape effects (different environments can be combined and matched to produce different plant combinations), extremely high ecological benefits (meeting the user's requirements for temperature and humidity, and at the same time improving the microclimate in combination with the external environment climate) all contribute to the wall The application of surface greening has brought a larger market, and at the same time can satisfy people's yearning for the construction of ecological civilization.

According to the survey, more than half of the families believe that home greening should occupy 11% to 20% of the family space, that is, most families think that indoor greening should be an important part of interior design; the acceptance rate of indoor planting walls in the survey is higher than that of traditional greening. , vertical greening can not only improve the climate, purify building gray water and rainwater, more importantly, in today's increasingly serious heat island effect, it is particularly important to increase the greening rate of the city, while traditional greening needs to occupy a large area of land, In the process of urban development, the planning area is very limited. At this time, we adopt vertical greening as a method that can better relieve the tension of land use and reduce the urban heat island effect. At the same time, the survey found that indoor vertical greening accounts for 45.28% of the decoration cost, and nearly half of the people are willing to accept indoor vertical greening; when the cost can be reduced appropriately, neutral people are more willing to choose vertical greening. This proves that the potential market for wall vertical greening is huge.

Although my country's outdoor planting walls have not been widely used on a large scale at present, Eco-Wall is an economically and environmentally friendly sustainable development project. It is believed that in the next few years, outdoor wall greening will gradually enter the country The city has set off a new upsurge in greening.

Then the irrigation problem of wall greening has become a problem that we need to consider and solve.
