The effects of land cover on urban-rural and intra-urban temperature differences have been extensively documented. However, few studies quantitatively related air to composition at a local scale which may be useful guide landscape planning design. In this study, the quantitative relationships between neighborhood in Beijing were investigated through field measurement campaign statistical analysis. results showed that had significant positive correlation with coverage man-made surfaces, but...

Urban parks reduce air temperatures within and surroundings by exerting the cooling island effect, significant for mitigating urban microclimate. However, park effect may be influenced surrounding building configuration, this needs to studied in more detail, particular, explore how maximize of adjusting configuration. Thus, study, effects height, interval, orientation on a small were investigated using field measurements ENVI-met numerical simulations. The results demonstrated that (1) all...

With the rapid worldwide urbanization, environment quality has been worsening dramatically. It is a solid fact that urban air temperature gradually rising in all cities and some effective measures are needed to mitigate it. Planting of vegetation one main strategies regulate microclimate heat island (UHI). This paper aims investigate effect tree community, mainly through shading, on improvement microclimatic conditions areas, specifically, case Beijing Olympic Forestry Park Beijing, China....

Urban parks are public green spaces which have a direct impact on the daily outdoor activities of residents and visitors due to their landscape functionality. To enhance spatial vitality services urban meet needs visitors, managers planners should focus people’s perceptions preferences park characteristics. This study aimed investigate relationship between visitors’ environmental factors in parks. Fixed-point photography mobile measurements were used quantify Unmanned aerial vehicle...

This study investigates the relationship between Green View Index (GVI) and street thermal environment in Hangzhou’s main urban area during summer, quantifying greenery’s impact on diurnal/nocturnal conditions to inform heat island mitigation strategies. Multi-source data (3D morphological metrics, LCZ classifications, mobile measurements) were integrated with deep learning-derived street-level GVI through image analysis. A random forest-multiple regression hybrid model evaluated...

Forest walking is a popular, healthy, and light outdoor activity. The potential comprehensive relationships between the vertical structures, thermal comfort, negative air ions (NAI), human physiological stress in forest spaces have not been determined. We performed an experiment Baishuihe National Nature Reserve, Sichuan Province, China. Thirty-two college students recruited as subjects completed walk (approximately one kilometer) on same trail divided into three structure type subsections,...

Urban greening is the most effective way to regulate microclimate environment and thermal discomfort. However, despite being an important type of vegetation, relatively few studies have investigated effect bamboo on characteristics comfort. In this study, differences in comfort provided by common communities East China were summer winter, effects canopy structure analyzed. The results showed that there significant between control check summer, but air temperature winter not obvious. daytime...

Soil temperature plays an important role in soil respiration, which is related to the atmospheric carbon cycle. In addition its own physical and chemical properties, also influenced by external environmental factors, including plants. Therefore, it relevant explore relationship between plant characteristics temperature. This study was conducted Hangzhou, China. The influence of canopy structural bamboo communities on investigated detail means field measurements. summer, structure reduced up...

Wetlands contain a large number of spontaneous plants, and the ecological value such plants should not be underestimated. However, influence surrounding environment on composition in wetlands is still unclear. Hangzhou Jiangyangfan Ecological Park, built more than 20 years ago, first park China based “wild state” concept. The wetland was taken as study case, we investigated some factors affecting diversity distribution pattern habitats after natural succession. A total 100 species were...
