Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a method for the formation of ground cover plant communities suitable for bioretention facilities, which solves the problem that the ground cover plant community structure in the current bioretention facility area is unreasonable, unstable, and has a single function. Inadequate functioning of ecosystem services

Embodiment 1

[0054] Example 1 is located at the intersection of a main road and an auxiliary road in a residential area. The bioretention facility to which Example 1 belongs is a part of the green separation belt, with an area of ​​about 80m 2 , and the sunshine habitat type is Sunshine (6h and above). The soil medium of the water storage area and the buffer zone of the bioretention facility is a medium soil formed by mixing primary soil, sandy soil and coir peat (the ratio is 4:4:2), and the soil medium in the edge area is primary soil. Example 1 The site mainly collects direct precipitation and rainwater runoff from the main road and auxiliary roads, and the pollution is relatively serious. The main pollutant types are: ammonium nitrogen compounds and phosphate compounds. Comprehensive assessment The bioretention facility to which Example 1 belongs belongs to the function-oriented type.

Embodiment 2

[0062] Example 2 is located near the main road of a certain city, and the bioretention facility to which Example 2 belongs is a part of the road green space, with an area of ​​about 100m 2 , and the sunshine habitat type is Sunshine (6h and above). The soil medium in the water storage area and the buffer zone of the bioretention facility is a medium soil formed by mixing primary soil, sandy soil and coir peat (ratio: 4:4:2), and the soil medium in the edge area is primary soil. The site in Example 2 mainly collects direct precipitation and rainwater runoff from surrounding road green spaces, with slight pollution. The bioretention facilities in Example 2 of the comprehensive assessment belong to the landscape-oriented type.

Abstract

The invention proposes a ground cover plant community composition method suitable for bioretention facilities, including evaluating the site where the bioretention facility is located, determining the ground cover plant community type and determining the ground cover plant community composition. The present invention introduces for the first time the habitat conditions of the site where the bioretention facility is located, including topography, soil medium, main pollutant types, pollution amount and sunshine characteristics, and comprehensively analyzes the environment and functional requirements of the site where the bioretention facility is located. The facilities are divided into zones, and the plant species are selected according to the habitat conditions of different regions, which can realize the rainwater runoff control and pollutant removal functions of the bioretention facilities, and at the same time, the stability of the community is guaranteed.

Description

Technical field: [0001] The invention relates to urban ecology and plant planting, in particular to a ground cover plant community organization method for biological retention facilities. Background technique: [0002] Bioretention facilities have good runoff pollution control effects, total runoff reduction effects, and rainwater interception effects. At the same time, they have become a widely distributed and large number of facilities in sponge cities because of their design scale, flexibility and aesthetics of layout and structure. type. The rational selection and design of plants is the key to the function of rainwater bioretention facilities. Due to the special habitat conditions, the plant selection and configuration methods are different from the traditional plant planting design. However, at present, the planting of bioretention facilities is mostly based on the perspective of plant survival and aesthetics in traditional planting design, and there is no in-depth co...
