Comprehensive evaluation of carbon sequestration potential of landscape tree species and its influencing factors analysis: implications for urban green space management

Abstract

Background Continuous increasing carbon dioxide (CO2) has aggravated global warming and promoted urban tree planting projects for many countries. So it’s imperative to select high carbon sequestering landscape tree species while considering their aesthetic values of urban green space. Results 32 tree species were selected as test objects which were commonly used in landscaping in Zhengzhou, a typical northern city of China. To assess the comprehensive carbon sequestration potential of landscape tree species in different plant configuration types, we simultaneously considered their daily net carbon sequestration per unit leaf area (wCO2), daily net carbon sequestration per unit land area (WCO2) and daily net carbon sequestration of the whole plant (QCO2) through cluster analysis. Besides that, we found out the key factors affecting carbon sequestration potential of landscape tree species by redundancy analysis. Conclusion Populus, P Stenoptera, P. acerifolia among large arbors (LA), V odoratissimum, P. Serratifolia, S. oblata among small arbors (SA), and B sinica var. Parvifolia, B. Megistophylla, L quihoui among shrubs (S) were recommended for local urban green space management. Photosynthetic rate (Pn), crown area (CA) and leaf area index (LAI) were the key factors which affected the comprehensive carbon sequestration potential both for LA, SA and S.

Comprehensive evaluation and application of woody plants in the green spaces of parks in saline–Alkaline areas from a low-carbon perspective: A case study of Tianjin Qiaoyuan Park

“…The research results indicate that the carbon sequestration capacity of plants in Qiaoyuan is slightly lower than reported in studies by Jin et al [71] and Chen et al [72]. This may be attributed to the poor soil quality and dry climate conditions in the area, which could lead to a decline in plant health and consequently reduce their carbon sequestration efficiency.…”

Ameliorating Effects of Graphene Oxide on Cadmium Accumulation and Eco-Physiological Characteristics in a Greening Hyperaccumulator (Lonicera japonica Thunb.)

“…Under GO treatments and Cd stress (T 5 , T 6 , T 8 , T 9 , T 11 and T 12 ), different concentrations of GO increased the carbon sequestration per unit leaf area and oxygen release per unit leaf area of the plant exposed to different concentrations of Cd, especially under 10 mg L −1 GO, where the carbon sequestration per unit leaf area and oxygen release per unit leaf area of the plant exposed to 5 mg L −1 Cd (T 5 ) were enhanced significantly by 38.89% higher than the GO0-Cd5 (T 2 ) treatment, which showed that the cooperation of low-concentration GO (10 mg L −1 ) and low-concentration Cd (5 mg L −1 ) could significantly stimulate the carbon sequestration and oxygen release functions of the plant ( p < 0.01). It is shown that the carbon sequestration per unit leaf area could predict the carbon sequestration capacity of plants through their photosynthesis, and therefore it was directly used for the evaluation of the carbon sequestration functions in different types of plants [ 103 , 107 ]. In the present study, L. japonica still kept an increase by 20.34% compared to the control even under 100 mg L −1 GO and 25 mg L −1 Cd (T 12 ) treatments, which indicated that the plant had a strong capacity of carbon sequestration under the mutual influence of environmental stress.…”

“…It is well known that carbon sequestration and oxygen release functions are considered as crucial parameters to assess the ability of plant photosynthesis [103]. To investigate Plants 2023, 13, 19 9 of 15 carbon sequestration and oxygen release functions, it is helpful to explore the ecological service function of the greening plants [104].…”

Carbon Fixation and Oxygen Release Capacity of Typical Riparian Plants in Wuhan City and Its Influencing Factors

“…Liu [9] studied the carbon sequestration and oxygen release capacity of Lonicera japonica, a common garden plant, and investigated the effects of cadmium stress on the growth, photosynthesis, carbon sequestration, and oxygen release characteristics of Lonicera japonica. Jin [10] studied the carbon sequestration potential of 32 typical tree species in Zhengzhou City. However, the carbon sequestration patterns of many unique greening species in riparian zones remain unclear, as most studies have focused on the carbon sequestration and oxygen sequestration capacities of terrestrial plants in urban gardens.…”
