Embodiment 1

[0083] Embodiment 1, the classification of garden plants

[0084] In this embodiment, garden plants are divided into three grades, and the specific process is:

[0085] (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;

[0086] (2) The root density characteristics of the above 70 kinds of plants were measured by a ground penetrating radar root scanner. Through the analysis of soil physical and chemical properties and principal component analysis, the initial permeability and stable permeability of the soil corresponding to the above 70 kinds of plants were obtained. The data rate of the relationship among the above-mentioned 70 kinds of plants is sorted on the comprehensive seepage-promoting ability of the soil;

[0087] (3) According to the relationship data between the above-mentioned root density and soil infiltration capacity, and the root d...

Embodiment 2

[0092] Embodiment 2, construct the root system seepage-promoting type garden plant community of high stepping frequency greenbelt

[0093] This embodiment is implemented under the following conditions of implementation and technical requirements:

[0094] 1. In Shanghai Xinzhuang Plum Garden (with a total area of ​​about 8000m 2 ) Build multiple 20m×20m root-seepage-promoting garden plant communities.

[0095] 2. The root-infiltration-promoting garden plant community is a multi-layer mixed plant community. It is divided into three parts: the rainwater collection zone, the leisure zone and the root-seepage-promoting zone in terms of horizontal structure. The planting areas are about 5m×20m and 7.5m respectively. ×20m and 7.5m×20m, the vertical structure is divided into upper, middle and lower floors.

[0096] 3. The upper layer is a layer of big trees and small trees.

[0097] Among them, evergreen small trees and deciduous small trees with strong rainwater root system infil...

Embodiment 3

[0109] Embodiment 3, construct the root system seepage-promoting type garden plant community of low trampling frequency greenbelt

[0110]This embodiment is implemented under the following conditions of implementation and technical requirements:

[0111] 1. Construct multiple 20m×20m root infiltration-promoting garden plant communities in Gongkang Greenland (about 5000m2) in Zhabei, Shanghai.

[0112] 2. The root-infiltration-promoting garden plant community is a multi-layer mixed plant community, which is divided into three parts: the rainwater collection zone, the root infiltration-promoting zone and the buffer transition zone in the horizontal structure, with an area of ​​about 5m×20m and 7.5m× 20m and 7.5m×20m, the vertical structure is divided into upper, middle and lower floors.

[0113] 3. The upper layer is a large tree layer;

[0114] Among them, in the rainwater collection zone with a length of about 20m and a width of about 5m in the upper planting area, small tre...

Abstract

The invention discloses a method for constructing a root system permeation enhancing landscape plant community. The method includes measuring root system data of common landscape plants and corresponding physical-chemical properties of soil, acquiring relation data between the landscape plants and soil permeation, ranking the comprehensive permeation enhancing ability of the landscape plants for the soil, and selecting landscape plant species having high permeation enhancing ability; dividing the landscape plants into a strong functional type, a intermediate functional type, and a weak functional type according to the comprehensive permeation enhancing ability of the landscape plants for the soil; and planting the landscape plants in a planting region in a complex manner, and forming a complex hybrid plant community. The complex hybrid plant community includes a landscape community suitable for high tread frequency green lands and a landscape community suitable for low tread frequencygreen lands. The constructed landscape plant community having high rainwater root system permeation enhancing ability can store permeated rainwater and reduce surface runoff, can generate ecological benefits and play an environmental function, and has an excellent landscape aesthetic function.

Description

technical field [0001] The invention relates to the technical field of gardens, in particular to a method for constructing a root-infiltration-promoting 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. They have ecological service functions such as improving microclimate, ...
