A waterfront forest construction method for subtropical mountainous cities based on native plants

Abstract

The invention discloses a method for constructing a subtropical mountain urban waterfront forest based on native plants in the field of ecological restoration. The method includes the following steps: S1: long-term field observation on the history and current situation of native species in the local waterfront space and consulting of relevant documents ; S2: formulate qualitative criteria for the selection of top pioneer species suitable for urban waterfront space, and include the plants of the top pioneer species; S3: select the top pioneer plants suitable for the subtropical mountain urban ecological environment according to the above criteria; S4: according to the site wetland conditions , the lower part of the arbor layer of the vertical structure of the waterfront forest community is equipped with water-resistant shrub layer plants. Adapt to the original bare land of the urban construction site, the large amount of green shade, the stable waterfront forest structure, enhance the biodiversity of the waterfront wetland, improve the level of ecosystem service functions, solve the endogenous secondary pollution of the previous graphic design and reduce manual management , Provide more summer urban cool source to meet social needs.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for constructing waterfront forests in subtropical mountainous cities based on native plants, and in particular to the problem of improving the ecosystem functions of waterfront sensitive areas in mountainous cities. Background technique [0002] The waterfront space is located at the key interface between two or more substances, energies, structures, and functions. With its superior hydrophilicity and comfort, it meets the needs of citizens for leisure, entertainment, and refreshing. It also belongs to the fragile zone of ecological environment. The urban waterfront space is an important area that constitutes the biodiversity of the urban ecosystem, and it is also one of the areas with the most abundant characteristics of the urban landscape. They are of extremely important value in improving environmental quality, protecting the ecology of mountainous c...

Problems solved by technology

[0003] For a long time, however, in terms of plant landscape design standards and configurations in the waterfront areas of mountainous cities, there are many exotic species in the screening of waterfront plants, the configuration of species structure violates ecological principles, and the single function of the plane and vertical structure of forest communities leads to poor system ecological service benefits. , Weak anti-risk ability, limited ability to purify pollution, serious endogenous secondary pollution, difficult post-management and high labor costs

In particular, megacities located in the subtropics have a hot summer climate, and the previous vegetation design based on herbaceous plants resulted in a lack of cooling sources in the waterfront space, and the ecological services and social benefits that the waterfront space should have have not been fully utilized.
