Subtropical mountainous urban waterfront forest construction method based on local territory plants

Abstract

The invention discloses a subtropical mountainous urban waterfront forest construction method based on local territory plants in the field of ecological restoration. The method comprises the steps that S1, the history and current situation of native species in local waterfront space are subjected to long-term field observation, and relevant documentation is consulted; S2, a qualitative standard for screening urban waterfront space adaptable top-level pioneer species is made, and plants of the top-level pioneer species are included; S3, the top-level pioneer plants adaptive to a subtropical mountainous urban ecological environment are screened out according to the standard; and S4, according to the field wetland situation, shrub layer plants which are resistant to water dampness are arranged below an arborous layer zone of a vertical structure in a waterfront forest community. The method is suitable for a primary bare area in urban construction section engineering, the shade volume is large, a waterfront forest is stable in structure, the biological diversity of a waterfront wetland is improved, the ecological system service functional level is increased, the problem of endogenous secondary pollution in previous planar design is solved, manual management is reduced, and more summer urban cool sources are provided to meet the demand of the society.

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.
