“…This study comprehensively estimated the direct and indirect low-carbon contribution of street trees. In comparison to previous studies, which only estimated the contribution of direct carbon sequestration, this research can better reflect the role of street trees in achieving carbon neutrality [49][50][51]. In this study, taking the London plane tree as an example, it was found that the average annual carbon sequestration of this tree species was 38.9 kg, which is an approximate value of USD 7.20; however, if its comprehensive low-carbon contribution were considered, this value reached USD 18.74.…”

Road traffic carbon emissions are an important cause of global warming, and street trees play an important role in regulating road carbon emissions. During urbanization, major differences in the planting management modes and growth status of the street trees in urban–suburban gradient may exist, leading to significant differences in the low-carbon values of the street trees in urban–suburban gradient. Based on this, this study took two typical urban–suburban gradient zones in Shanghai as an example to analyze the changes in the characteristics of street tree species, planting density, tree sizes, and low-carbon contribution with urban and rural changes, and proposed strategies for optimizing the low-carbon contribution of urban street trees. The results showed that, from the inner ring to the outer ring and the suburban ring, the proportion of London plane tree gradually changed from 82% to 11%, and the proportion of the camphor tree gradually changed from 9% to 70%; the average DBH of the trees gradually decreased from 28.81 to 23.74 cm. The number of plantings per unit road length gradually increased, and the number of plantings per unit area gradually decreased; therefore, the average low-carbon contribution of urban–suburban street trees is not significant, but the low-carbon contribution of upper street trees per unit area is higher, and suburban unit street trees have a higher low-carbon contribution. Finally, this article proposes different optimization strategies for future urban micro-renewal and suburban new-city construction.

“…The urban residents typically use the term "natural forest" more commonly than "urban forest" even though they have more experience with urban forests than natural forests outside cities. In Malaysia, the concept of the term "urban forest" is not new, but the focus has traditionally been on natural forests and forest plantations; however, the use of this term in research has been steadily increasing in recent times, indicating a growing interest in this field [20]. The rise in urban forest research can be attributed to accelerated urbanization and a growing awareness of the need for sustainable development in Malaysia.…”

Permanent forest reserves (PFR) in urban areas are an integral aspect of the urban forest concept and the basis of a city’s green infrastructure. The preservation of natural forests in urban areas has become a widely researched topic due to the environmental, social, and economic benefits provided by it. Although several studies have shown that visual aesthetics play a role in preserving natural forests in urban areas, visual aesthetic value is typically not prioritized in preservation plans since it varies based on the physical characteristics of natural forests in urban areas, making it difficult to measure universally. Therefore, this research aims to identify the suitable variables for assessing the visual aesthetic quality of permanent forest reserves within urban areas in Malaysia. This study selected two permanent forest reserves based on four criteria. Data were collected via participant-generated images taken along selected forest trails based on participant visual aesthetic preferences. Researchers and experts analyzed and classified the data according to content to identify suitable visual aesthetic quality variables. This research identified 14 suitable variables for assessing the visual aesthetics of PFRs in urban areas, with a dominant preference for information-processing theory variables. Mystery was the most present variable for the visual aesthetic quality assessment of PFRs. Furthermore, participants’ educational and emotional backgrounds, categorized as design, environmental, social, and technical, impacted their visual aesthetic preferences. Our findings serve as a foundation for assessing the visual aesthetic quality of natural forests within urban areas in Malaysia.

“…The increase in CO 2 in the air leads to global greenhouse and urban heat island effects, which adds to global warming [2,3]. As an essential carbon sink base, forest ecosystems can alleviate the global greenhouse effect by regulating the global carbon-oxygen balance [4][5][6]. Forests maintain the global carbon-oxygen balance through carbon release and oxygen consumption (CROC) processes and carbon sequestration and oxygen release (CSOR) processes [7,8].…”

The urban forest is a vital carbon sink base in a city. The carbon-oxygen balance capacity of urban forests affects the urban carbon cycle and urban sustainable development. The forests maintain the carbon-oxygen balance through carbon sequestration and oxygen release (CSOR) processes. The carbon-oxygen balance of urban forests is formed by offsetting the carbon release and oxygen consumption (CROC) process of urban social activities through the CSOR process of forestland. Based on GIS technology, this research used the carbon-oxygen balance model to analyze the CROC and CSOR and study the carbon-oxygen balance of urban forests in the southern mountainous area of Jinan, China. The results of the increase in the carbon-oxygen balance coefficients showed that the carbon-oxygen balance capacity of urban forests showed a decreasing trend, with the decrease in forest area and the increase in fossil energy consumption from 2000 to 2019 in the southern mountainous area of Jinan. To increase the urban carbon-oxygen balance capacity, the city should expand its woodland area to improve the urban forest’s CSOR capacity and adjust the urban energy consumption structure to reduce the CROC of urban social activities.
