Problems solved by technology

[0003] At present, domestic scholars mainly focus on the investigation and evaluation of the structure, species diversity, and function of plant communities, and there are not many studies on applied plant communities.
At the same time, the current technical means lack ecological design methods for large-scale fragmentation and small-scale urban green space

Embodiment 1

[0051] This embodiment provides a method for establishing an artificial ground cover plant community, which mainly includes site preparation (evaluation and improvement of soil quality), plant community establishment, and continuity design.

[0052] The first step is to evaluate the soil quality. Firstly, the site soil is evaluated from three aspects: the site land use history and soil, the current vegetation and soil, topography, hydrology and soil, so as to clarify the parts of the site soil that need to be preserved and protected, and the needs The repaired part, the removed part, the part that can be effectively used or transformed and the part that cannot be used, and the soil information collected above will be graphically expressed, such as the soil habitat zoning map of the site, and based on this Site soil improvement: (1) Site soil use history and soil, that is, in the long-term site evolution process, the site soil may undergo great changes due to changes in land use...

Embodiment 2

[0057] This embodiment provides a design for the artificial ground cover plant community structure. In practice, the vertical structure is divided into three layers, including a ground cover layer and two planting layers. The ground cover layer uses pine forest and gravel as the ground covering material, and the planting layer adopts a two-layer structure of structural layer + seasonal theme layer. In the structural layer, one plant was selected as the construction species of the community, and in the seasonal theme layer, two plants were selected as the dominant species.

[0058] In the sun habitat, Sedum sedum was used as the construction species, and two community models were formed, A1 (Sedum sedum + stachys syringae + wood spring chrysanthemum) and A2 (Sedum sedum + yarrow + ground cover carnation), With Phalaenopsis as the constructing species, two community patterns were established: B1 (Pascophyllum + Rushgrass + Carex laoyu) and B2 (Physeophyllum + Huoxiang + Penniset...

Embodiment 3

[0061] This embodiment provides a design for the artificial ground cover plant community structure. In practice, the vertical structure is divided into three layers, including a ground cover layer and two planting layers. The ground cover layer uses pine forest and gravel as the ground covering material, and the planting layer adopts a two-layer structure of structural layer + seasonal theme layer. In the structural layer, one plant was selected as the construction species of the community, and in the seasonal theme layer, two plants were selected as the dominant species.

[0062] In the shade habitat, the broad-leaved Ophiopogon japonicus was used as the construction species, and two community models were constructed, C1 (Ophiopogon japonicus broad-leaf + Rush + green onion) and C2 (Ophiopogon broad-leaved + Equisetum + Oxalis safflower). Kidney fern is the constructing species, and it has two community patterns: D1 (kidney fern + hosta + sex) and D2 (kidney fern + alum root ...

Abstract

The invention provides a plant community construction method. A plant community constructed by the method is suitable for the climate and soil environment of the northwest regions, and the method comprises the following steps: (1) soil quality evaluation; (2) soil improvement; (3) plant community construction; and (4) continuity design. The plant community construction method has the effects thatthrough the combination of ecology and design creation as well as the application of a principle of plant community science, site design is taken as a starting point, and the basic method for constructing the ground cover plant community on a site scale is proposed; the characteristics of regional climate, environment and typical engineering habitats are taken into full account, and based on the differences in vegetation structure characteristics and functional roles, a layered design pattern of structural layer + seasonal theme layer + ground cover layer is innovatively proposed.

Description

technical field [0001] The invention relates to the technical field of urban ecology and landscape construction, in particular to a method for constructing artificial ground cover plant communities in Northwest China. Background technique [0002] Plant communities have the potential to stably improve urban species diversity and ecosystem service functions, while ground cover plant communities are irreplaceable for the composition of urban biodiversity. Ground cover plants and native plants can effectively improve urban biodiversity. The vegetation community has the possibility to adapt to the small space of the narrow block, which is beneficial to the reproducibility and applicability in the urban habitat. Therefore, the ground cover plant community structure can effectively deal with the ecological design of small-scale green space units in the subsidiary green space. Moreover, due to the arid and semi-arid precipitation conditions, seasonal rainfall and other inland clim...
