“…Therefore, the ecological and environmental development roles of integrating greenery systems in the transport, and built areas is of paramount functions [22,26,58,59,[62][63][64][65][66][67][68][69][70][71][72][73]. We can ably argue that the urban dwellers also enjoy psychological benefits from interacting with urban nature [74][75][76]. By merely looking at nature, it is very relaxing for the brain and body for some people.…”

This study aimed to explore the case study of Brno city regarding smart city models. We analyzed Brno considering smart and sustainable city elements, i.e., smart mobility/public transport, smart technology, smart people, smart governance, smart economy, smart living, and smart environment based on transport, energy, and environment referred herein as the smart city and sustainability model. Therefore, we investigated a case study of Brno city in the Czech Republic. We used qualitative techniques such as case study, exploration, observation, and description. We analyzed and comprehended the trends in the various features of smart city and sustainable development of the city of Brno. The findings showed that Brno city is doing its best to maintain smart city models through its governance organs and structures. The city is also working hard to improve some of the aspects that are still lagging. The ongoing developments and the future ones are based on strategic planning for both the short term and long term such as Brno2023, Brno2030, and Brno2050. It was found that Brno has a very well-planned transport system and is integrated with other aspects such as technology, energy, such as the electricity that moves the trolleybuses and trams, and environment. We strongly conclude that even though Brno city still struggles to achieve total sustainability, it is still a model and reflection of a smart and sustainable city. Finally, we noted that Brno city has very good plans and vision the “DNA” of a smart city. However, the implementation still suffers political willingness.

“…In a world of increasing urbanization, atmospheric particulate matter (PM) pollution mitigation is currently one of the most critical city planning issues. Urban trees are of central importance for this issue because they facilitate the deposition of various gases and particles and affect microclimate and air turbulence [1][2][3][4]. The urban PM contains harmful components such as heavy metals, which seriously affect the health of urban residents [4,5].…”

Background Functional trait-based ecological research has been instrumental in advancing our understanding of environmental changes. It is still, however, unclear how the functional traits of urban plants respond to atmospheric particulate matter, and which trade-off strategies are shown. In order to explore the variation of plant functional traits with the gradient of urban atmospheric particulate matter, we divided atmospheric particulate matter into three levels according to road distance, and measured the variation of six essential leaf functional traits and their trade-off strategies. Results Here, we show that the functional traits of plants can be used as predictors of plant response to urban atmospheric particulate matter. Within the study, leaf thickness, leaf dry matter content, leaf tissue density, stomatal density were positively correlated with atmospheric particulate matter. On the contrary, chlorophyll content index and specific leaf area were negatively correlated with atmospheric particulate matter. Plants can improve the efficiency of gas exchange by optimizing the spatial distribution of leaf stomata. Under the atmospheric particulate matter environment, urban plants show a trade-off relationship of economics spectrum traits at the intraspecific level. Conclusion Under the influence of urban atmospheric particulate matter, urban plant shows a “slow investment-return” type in the leaf economics spectrum at the intraspecific level, with lower specific leaf area, lower chlorophyll content index, ticker leaves, higher leaf dry matter content, higher leaf tissue density and higher stomatal density. This finding provides a new perspective for understanding the resource trades-off strategy of plants adapting to atmospheric particulate matter.

“…Numerous studies have demonstrated that the contribution of plants to the urban environment is extensive and far-reaching, as plants play an important role in biodiversity conservation [7,8], improving microclimates [9][10][11], relieving air pollution [12,13], enhancing aesthetic value [14], and even influencing the psychological behavior of city dwellers [15,16]. However, urban managers, urban forestry and landscape scientists are more concerned with the sustainable selection and cultivation of plants [17][18][19], these core benefits not only have advantages in planting and management costs, but the eco-functions are also dependent on their survival, growth, development and reproduction [20,21].…”

A Digital Framework to Predict the Sunshine Requirements of Landscape Plants

et al. 2021

Knowledge of the sunshine requirements of landscape plants is important information for the adaptive selection and configuration of plants for urban greening, and is also a basic attribute of plant databases. In the existing studies, the light compensation point (LCP) and light saturation point (LSP) have been commonly used to indicate the shade tolerance for a specific plant; however, these values are difficult to adopt in practice because the landscape architect does not always know what range of solar radiation is the best for maintaining plant health, i.e., normal growth and reproduction. In this paper, to bridge the gap, we present a novel digital framework to predict the sunshine requirements of landscape plants. First, the research introduces the proposed framework, which is composed of a black-box model, solar radiation simulation, and a health standard system for plants. Then, the data fitting between solar radiation and plant growth response is used to obtain the value of solar radiation at different health levels. Finally, we adopt the LI-6400XT Portable Photosynthetic System (Li-Cor Inc., Lincoln, NE, USA) to verify the stability and accuracy of the digital framework through 15 landscape plant species of a residential area in the city of Wuhan, China, and also compared and analyzed the results of other researchers on the same plant species. The results show that the digital framework can robustly obtain the values of the healthy, sub-healthy, and unhealthy levels for the 15 landscape plant species. The purpose of this study is to provide an efficient forecasting tool for large-scale surveys of plant sunshine requirements. The proposed framework will be beneficial for the adaptive selection and configuration of urban plants and will facilitate the construction of landscape plant databases in future studies.
