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 three-dimensional community with a large leaf area constructed by applying south subtropical tree species and a construction method thereof. The present invention applies the dominant broad-leaved tree species in the south subtropical zone to set up plant communities with multiple levels in space, and the plant canopies falling on each level belong to plant species with large leaf area characteristics on the same height dimension; The plant community built on the plant has the characteristics of large total leaf area, which can play a better role of air filtration 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...
