Embodiment 1

[0051] The classification of embodiment 1 landscape plants

[0052] Garden plants are divided into three grades in the present embodiment 1, and concrete process is:

[0053] (1) Select representative artificial plant communities in urban gardens and green spaces, and screen 70 species of plants with a frequency greater than 10% through community surveys;

[0054] (2) Measure the water storage capacity per unit area and the leaf area index of the above-mentioned 70 kinds of plants, so as to obtain the potential water storage capacity per unit area of ​​each plant, and the water storage capacity per unit area is proportional to the storage capacity per unit area of ​​the leaves. The product of the amount of water and the leaf area index;

[0055] (3) According to the potential water storage capacity of the unit area, the garden plants are divided into three grades of strong function, medium function and weak function or landscape, as shown in Table 1. To build a garden plant ...

Embodiment 2

[0059] The construction of embodiment 2 water storage type garden plant communities

[0060] This embodiment 2 is implemented under the following conditions of implementation and technical requirements:

[0061] 1. In Shanghai Zhabei Gongkang Greenland (with a total area of ​​about 8000m 2 ) Construct multiple 20m×20m water-storage garden plant communities.

[0062] 2. The water-storage garden plant community is a multi-layer mixed plant community, which is divided into three parts: the rainwater storage zone, the buffer infiltration zone and the runoff delay zone in the horizontal structure. The planting areas are about 15m×10m and 10m× 10m and 10m×15m, the vertical structure is divided into upper, middle and lower floors.

[0063] 3. The upper layer is a large tree layer.

[0064] Among them, evergreen trees and deciduous trees with strong functions, ie strong rainwater storage capacity and excellent landscape, are planted at intervals in the rainwater storage belt with a...

Embodiment 3

[0075] The construction of embodiment 3 water storage type garden plant communities

[0076] Present embodiment 3 is implemented under the following implementation conditions and technical requirement conditions:

[0077] 1. In Shanghai Minhang Huangdaopo Greenland (about 5000m 2 ) Construct multiple 20m×20m water-storage garden plant communities.

[0078] 2. The water-storage-type garden plant community is a multi-layer mixed plant community, which is divided into three parts: the rainwater storage zone, the buffer infiltration zone and the runoff delay zone in the horizontal structure, with an area of ​​about 15m×10m and 10m×10m respectively and 10m×15m, vertical structure is divided into upper, middle and lower floors.

[0079] 3. The upper layer is a large tree layer.

[0080] Among them, evergreen trees and deciduous trees with strong functions, ie strong rainwater storage capacity and excellent landscape, are planted at intervals in the rainwater storage belt with a l...

Abstract

The invention discloses a method for building a water storage type landscape plant community. The method includes the concrete steps that landscape plants are divided into a high functionality level, a medium functionality level and a low functionality level according to the water storage capacity per unit area; the landscape plants at all the levels are planted in a planting area in a combined mode to form the multiple-layer mixed plant community, the multiple-layer mixed plant community comprises a horizontal structure and a vertical structure, according to the area ratio of 3:2:3, the planting area is divided into a rain water storing and retaining zone away from a boundary, a buffering and infiltrating zone located in the middle part and a runoff retardation zone close to the boundary by the horizontal structure in the direction parallel to roads and the water edge boundary, and the planting area is divided into an upper layer, a middle layer and a lower layer by the vertical structure. The water storage type landscape plant community built by the method can play a role in storing and retaining rain water and reducing overland runoff, and bring ecological benefits and the environmental function into play, and has the excellent landscape aesthetics function.

Description

technical field [0001] The invention belongs to the technical field of gardens, and in particular relates to a method for constructing a garden plant community, in particular to a method for constructing a water storage type garden plant community. Background technique [0002] With the rapid development of urbanization, changes in urban land use and coverage have led to the continuous increase in the area of ​​impermeable land coverage such as roads, squares, and buildings in the city, which has forced the interruption of the original natural hydrological cycle. It has caused environmental problems such as accelerated urban surface runoff, excessive gray infrastructure load, lack of replenishment of groundwater, loss of water resources, and even urban waterlogging. It has also increased the cost of urban garden and green space maintenance. Urban gardens and green spaces are an important part of maintaining urban ecological balance and creating a suitable living environment....
