Study On Vertical Planting And Its Ecological Benefits

Based on a large quantity of correlation data,fact-finding and analysis,According to the object for planting and the materials,this text make a detailed research on the conception,development,contents,mode,plant-selection,design,execution and resource of Vertical-planting. Four basic type of Vertical-planting were made.1. Architectural external wall and solid boundary wall planting.2. Arbor,fence and column planting.3. Overpass,viaduct,rockery and slope protection planting.4. Roof,terrace,sill and platform planting.This text analysis the specialty of every categories and bring out the problem which should be attention on plant-selection,design and execution. Based on fact-finding and analysis,100 kinds of plants fit for vertical planting are introduced.With all-round research on the four categories,a comparative study on the ecological environment benefits of four different plants in Chengdu were made. It shows that Parthenocissus trcuspidata has higher bactericidal capacity,Mucuna sempervirens have stronger bactericidal capacity and absorbing capacity of toxic gas. Rosa banksiae Ait get much ability of cooling down,humidification,absorbing sulfur dioxide,removing dust and keeping balance between carbon and oxygen in atmosphere. Integrated evaluating,Rosa banksiae Ait is the most valuable plant on ecological function among the four Vertical-planting plants. The others are Mucuna sempervirens,Parthenocissus trcuspidata,Wistaria sinensis Sweet in turn.According to the distinction of ecological functional of these four plants,the kind of plants which should be chosen under various ecological environment conditions or for different demands of ecological function of the plants were given.1. The most suitable plants for the area which get serious pollution such as factory,roadway and so on is Mucuna sempervirens.the other plant which more suitable is Rosa banksiae Ait.2. The most suitable plants for the hospital and the area for the children and the old is Mucuna sempervirens. And we can also select Parthenocissus trcuspidata.3. In the green area of modern enterprise that produce precision instrument,Rosa banksiae Ait is the best selection.4. Rosa banksiae Ait is the most suitable plants in resident green area. Planting Mixed with Mucuna sempervirens has better effectiveness.
