Embodiment 1

[0028] 1. The type and layout of the evaluation sample tree group

[0029] (1) Tree group types of evaluation samples The evaluation sample tree groups include three types of plant tree groups (mainly deciduous tree species, mainly evergreen tree species, and mainly native tree species), and these three types of evaluation sample tree groups are an evaluation sample group .

[0030] (2) Tree group layout of evaluation samples The tree group layout of evaluation samples requires a total of 6 tree groups (two evaluation sample groups), of which 3 are evenly distributed in urban park green spaces (one evaluation sample group); other urban green spaces Medium (such as scenic forest belt green space, scenic forest belts on both sides of the ring road elevated, etc.) layout 3 (one evaluation sample group).

[0031] 2. Test and calculation of the total leaf area of ​​tree species in the evaluation sample tree group

[0032] (1) Test and calculation of the crown volume of the sample...

Embodiment 2

[0056] 1. The type and layout of the evaluation sample tree group

[0057] (1) Evaluation of the type and location of the sample tree group

[0058] The evaluation sample 1 along the ring elevated line belongs to the conservation-type plant tree group dominated by deciduous tree species. There are 193 species of trees and shrubs in this tree group, including: Ginkgo bilobacv. Dafozhi: 7 strains, elm (U. pumila): 4 strains, eucalyptus (Koelreuteria paniculata Laxm.): 65 strains, magnolia (Y.denudata (Desr.) D.L.Fu): 1 plant, Cinnamomumcamphora (Linn.) Presl): 4 plants, Osmanthus fragrans: 72 plants, Acerpalmatum 'Bloodgood': 31 plants, Sakura (Prunus serruiata Lindl): 2 plants, Octagonal Golden Pan (Fatsiajaponica): 7 plants.

[0059] The research sample 2 along the ring-elevated line belongs to the thrifty plant tree group dominated by evergreen tree species. There are 134 species of trees and shrubs in this tree group, including: Cedar (Cedrusdeodara): 21 plants, Cypress (...

Abstract

The invention discloses an assessment method for oxygen releasing quantity of urban landscaping woodlot and application thereof. The invention relates to the assessment method for oxygen releasing quantity under annual photosynthesis of plant woodlot community. According to the assessment method, three urban landscaping woodlot ecological assessment quantitative indexes, namely 'assessment for annual oxygen releasing quantity of sample woodlot tree species', 'annual oxygen releasing quantity of single assessed sample woodlot' and 'annual oxygen releasing quantity of average unit area of a plurality of assessed sample woodlots', are calculated, assessed and acquired by determining and assessing leaf area or leaf weight of woodlot tree species, average net photosynthetic rate of woodlot tree species, annual sunshine hour of evergreen species or annual sunshine hour of deciduous species, and the like, and are used for assessing the urban landscaping environmental and ecological effect. According to the assessment method, the limited urban land space is utilized, the scientific basis is supplied for reasonably adopting saving-type woodlot community for designing and constructing coenotype woodlot greenbelt, and the exertion of greening ecological function can be benefited.

Description

technical field [0001] The invention relates to a method for evaluating the environmental ecological effect of the annual oxygen release amount of a plant tree community and its application. Background technique [0002] The importance of oxygen to life is self-evident. The oxygen in the air we live on comes from the photosynthesis process of plants. Urban greening plants provide a continuous source of oxygen for the urban environment, but how much oxygen do these greening plants provide for the urban environment in a year? How to evaluate and calculate the main form of urban greening—the annual release of oxygen by tree groups and its environmental effects? There is no quantitative evaluation method for these problems. [0003] It is well known that during photosynthesis, plants will absorb carbon dioxide (CO 2 ) and the water uptake by roots from the soil (H 2 O) converted to carbohydrates (CH 2 O)n, while releasing oxygen (O 2 ). The photosynthetic reaction equatio...
