Along with urbanization and industrialization, carbon emissions have been increasing significantly, resulting in global warming. Green space has widely accepted as a natural element cities to directly increase sinks indirectly reduce emissions. The quantification of benefits generated by green is an important topic. This paper aims provide comprehensive review the methods for measuring spaces. results indicate that existing assessment can accurately estimate spaces at large scales. However, are not fully applicable studies urban spaces, due low precision research results. assimilation method most suitable study sequestration efficiency plants project scales through macroscopic means. Even though, experiments unstable under different weather conditions. To address challenges, this proposes photosynthetic rate estimation based on light-response curve which efficient describe relationship between light intensity net studying plant physiological characteristics. newly proposed method, integrating photosynthesis-light response curves associated meteorological data, advantages short measurement time ensuring standardized experimental environment result comparability. Overall, combine meteorology physiology propose optimizing sink more convenient application its simple process In practice, provides guidance low-carbon planning design, helps promote energy conservation emission reduction nature-based solutions.

The assessment of human perception the thermal environment is becoming highly relevant in context global climate change and its impact on public health. In this study, we aimed to evaluate suitability use four frequently used comfort indices (thermal indices)–Wet Bulb Global Temperature (WGBT), Heat Index (HI), Physiologically Equivalent (PET), Universal Thermal Climate (UTCI)–to assess three large urban parks Central Europe, using Prague, capital Czech Republic, as a case study. We investigated relationship between park visitors, while taking into account effect sex, age, activity respondents week-time daytime their visit (assessed parameters). Park visitors were interviewed during summertime, collecting meteorological data. correlations performed explore individual indices, multivariate statistical methods explain how well variation can be explained by assessed parameters. found significant association all perception; however, was strongest with HI. While independent sex week-time, physical activity, visit. Nevertheless, effects largely conditions. Based results, conclude that are suitable for studies Europe HI seems most architects planners.

Evaluation and Analysis of the Impact of Coastal Urban Impervious Surfaces on Ecological Environments

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, Год журнала: 2023, Номер 16, С. 8721 - 8733

Urbanization as a human activity alters the surface structure, modifying urban ecological environment. In this study, greenness, wetness, building index, and heatness of Dalian, coastal city in northeast China, were extracted from summer MODIS remote sensing data 2010 2022, index (RSEI) was created based on spatial principal component analysis. The artificial impervious fraction (AISF) Dalian to analyze impact expansion environment with background urbanization, temporal change characteristics 2022 thoroughly evaluated. results show that: (1) Dalian's RSEI primarily ranged 0.2 0.8. During 2010-2022, built-up areas decreased 0.2-0.4 0-0.2. However, approaching 1 have increased significantly past ten years, mainly distributed original forest land or northern Dalian. (2) From natural showed positive development which, area enhanced quality accounted for 59.09%; however, proportion greater than 0.8 declined 76.64% 51.05% rose 1.11% 11.85%, demonstrating that urbanization has had substantial altered use structure. (3) AISF center found exceed 70% is centered south's densely area. boundary extending surrounding territory an ranging 20%–70%. This study objectively analyzed geographical features environment, well offers constructive recommendations design population distribution optimization.

Global climate change is causing various negative impacts on urban ecosystems and energy systems. To effectively mitigate adapt to these changes, it important understand the contributions of background local effects thermal environment variation. This study utilized empirical orthogonal function (EOF) approach deconstruct long-term MODIS land surface temperature (LST) datasets obtain main features in daytime nighttime environments. Local bivariate spatial autocorrelation analysis was used explore underlying causes changes. The EOF modes explained 73.14% 81.33% variation, respectively. correlation coefficient between time average LST > 0.99, reflecting role global effect caused by change. secondary 12.51% 4.12% respectively, were spatially correlated with changes landscape intensity, anthropogenic heat emissions. In expansion renewal areas, industrial zones compact high-rise buildings had most obvious warming environment, while mid-to-high-rise environment. results this provide valuable insights into mechanisms a reference for formulating effective strategies mitigating adapting promoting sustainable development.

Developing an Urban Environment Examination System by Incorporating Construction, Economic, Environmental, Cultural and Development Dimensions

Sustainability, Год журнала: 2024, Номер 16(7), С. 3065 - 3065

Опубликована: Апрель 7, 2024

The sustainable development goals (SDGs) suggest cities and communities (Goal 11) as inclusive, safe, resilient, human settlements. However, existing efforts in urban sustainability have mainly focused on ecological environmental sustainability, with little attention paid to development, economic, cultural sustainability. Moreover, a lack of adaptability is barrier cross-nation or cross-region implementation many frameworks due diverse contexts. Furthermore, most studies developed guides only for one-time assessments the progress has been neglected. Improving by considering multiple dimensions local through dynamic assessment remains question. Therefore, this study aims develop an environment examination system (UEES) framework that includes construction, economy industry, resource, municipal facilities, potential dimensions. UEES consists 31 indicators associated critical information (i.e., reported statistical yearbooks) from different levels government China. An annual update data ensures availability data, allowing managers decision makers regularly track was applied Qingdao, urbanizing city China, examine feasibility framework. results indicate well-urbanized districts could perform better terms overall (e.g., Shinan, Shibei, Laoshan, Chengyang), while suburban outer areas had lower levels. not all than districts. transition less-urbanized lead deterioration deceleration (if industries are well upgraded), but culture can be improved. Overall, provides methodological prioritizes comprehensiveness regular examinations China reference improvement identifying aspects low scores

Investigating the nonlinear impacts of urban landscape and climatic parameters on temperatures, a critical issue within climatology. Chengdu, characterized by its hot, rainy summers rapid development, serves as an ideal model to illustrate these dynamics. Our investigation utilizes advanced analytical methods such Random Forests (RF), SHapley additive explanation (SHAP), Partial Dependence Plots (PDP) analyze how factors influence air temperature (AT) land surface (LST). Significant findings reveal profound thermal heterogeneity across Chengdu's fabric, underscored spatially distinct phenomena where some regions exhibit strong contrasts in due varying factors. The study identifies relative humidity rainfall key drivers variations during summer months, reflecting specific idiosyncrasies. These insights are critical, they highlight planning green infrastructure can be strategically used mitigate adverse effects. research not only enhances understanding complex interplays microclimates but also offers new perspectives heat management. It contributes scientific community providing evidence-based strategies for planners counter island effect enhance resilience against climate change. This comprehensive analysis underscores importance incorporating multiple variables into models, lays groundwork more refined environmental policies practices.
