Embodiment 1

[0031] 1. Analysis of leaf area characteristics of dominant tree species in subtropical evergreen broad-leaved forest

[0032] The tree species used are the dominant species of evergreen broad-leaved forest in the south subtropical zone. They have the characteristics of vigorous growth, less pests and diseases, and strong adaptability. They are very suitable for the construction of urban green belts in the south subtropical zone.

[0033] By collecting the field survey and measurement data of 236 individuals of 56 species, the leaf area ratio (Leaf area ratio) of 56 tree species was obtained, that is, the leaf area LAB per unit of aboveground biomass (Poorter et al.2012), which was used to characterize Proportion of species' aboveground biomass allocated to leaf area. The calculated LAB of each tree species is a characteristic constant. The corresponding data are detailed in Table 1.

[0034] Survey and measurement refer to Poorter et al. 2012 (Poorter, H., K.J. Niklas, P.B....

Abstract

The invention discloses a large-leaf-area three-dimensional community constructed by applying southern subtropical tree species and a construction method thereof. Southern subtropical dominant broad-leaved tree species are used, a plant community with a plurality of layers is established in space, and a plant canopy falling on each layer belongs to a plant species with a large-leaf area characteristic on the same height size; and the plant community constructed in space by using the method has a characteristic of a large total leaf area and can play a better role of an air filtering barrier in urban roads.

Description

technical field [0001] The invention belongs to the technical field of ecology, and in particular relates to a three-dimensional community with large leaf area constructed by applying south subtropical tree species and a construction method thereof. Background technique [0002] Air pollution is a major environmental problem facing cities today (Sawidis et al 2012.). With the rapid development of industry and the acceleration of urbanization, a large number of toxic and harmful substances are discharged into the atmosphere through industrial emissions, fossil fuel combustion, transportation, etc., resulting in deteriorating urban air quality (Seaton et al.1995; Mayer 1999) . [0003] Urban greening plants play a huge role in air purification. The air-purifying function of plants is mainly performed through plant leaves (Prusty et al. 2005; Sharma and Roy 1997). Plants remove pollutants in the air through a series of processes such as canopy interception and leaf adsorptio...
