Analysis of micro-climate on the programs of urban infrastructure regeneration in J city,Republic of Korea

The purpose of this study is to simulate urban micro-climate change due to the variation of wind flow and temperature assuming situations before and after applying programs using urban infrastructure regeneration technologies (UIRTs), and to then quantitatively estimate effectiveness on the urban regeneration schems. UIRTs focus on improving the recycling efficiencies of reclaimed water and biogas produced and to enforce the linkage among all environmental infrastructures associated with water, waste, and energy in an urban block. To implement the micro-climate analyses, data such as land use, topography, building height and materials, and weather conditions were collected, and the results estimated based on fluid simulations of cold wind and temperature variation pathways. There were three programs used in the urban regeneration project in J city: river restoration, traditional market revitalization, and a primary school eco-school. The height of cold wind from the ground level was significantly elevated, and the maximum wind velocity differential between before and after increased by 0.12 m/s due to the expansion of the waterfront space and grassland through the three programs. Overall, a temperature at the ground level dropped by 1.6 °C. Based on these results, the three programs improved the urban environment at ground level, and might ultimately be capable of diminishing the urban heat island effect and mitigating the energy consumption of urban areas.     

Comparing conventional manual measurement of the green view index with modern automatic methods using google street view and semantic segmentation

Urban greenery has various beneficial effects, such as engendering peace of mind. The green view index (GVI) effectively measures the amount of greenery people can perceive and is a suitable indicator of urban greening. To date, the most common way to measure the GVI has been to photograph the street environment from eye level and use image-editing software to calculate the area occupied by vegetation. However, conventional methods are time-consuming and labor-intensive, and the calculation results may vary among individuals. In recent years, the use of Google Street View (GSV) photos and calculation of the GVI using automatic image segmentation have rapidly developed. In this study, we demonstrate the advantages of GSV and image segmentation over conventional methods, verify their accuracy, and identify the shortcomings of modern methods. We calculated the GVI in the central part of Sapporo, Japan, using the automatic image segmentation AI “DeepLab” and compared the results with those measured by Photoshop. At the exact GSV locations, we also acquired photos and again calculated the GVI using AI, subsequently comparing the results with those obtained on-site manually. Although the correlations were high, automatic image segmentation tended not to identify lawns and flowers planted in the ground as vegetation. It was impossible to determine the year when the GSV photos were taken. In addition, the distance to greenery was biased, depending on the position on the street. These points should be considered when using these modern methods.     

西峰黄土高原地温对梨树发育期的影响

用西峰黄土高原1971—2005年5、10、15、20cm地温和1984—2005年梨树发育期资料,分析了地温的时间变化规律及其对梨树发育期的影响。结果表明,西峰10cm地温,除夏季外,其余季节呈持续升高的趋势,春季增温最明显,变幅也最大;冬季增温幅度次大;秋季增温幅度最小。冬季、春季地温与梨树的各发育期均为负相关,即地温高发育期早,地温低发育期迟。冬季地温与梨树发育期相关最显著的是叶变始期和开花始期,相关系数为-0.41~-0.52,信度为0.05;春季地温与之相关最显著的是开花始期,相关系数为-0.68~-0.69,信度达0.001。春季地温对梨树发育期的影响具有明显的持续性和滞后性,冬季地温对梨树发育期影响有阶段性,春季地温对梨树发育期的影响比冬季明显。     

地被植物与高尔夫球场景观绿化

在高尔夫球场景观绿化中地被植物的应用越来越受到重视,成为不可缺少的高尔夫球场景观的组成部分,通常在乔木、灌木和草坪组成的自然群落之间起着承上启下的作用.同时,由于高尔夫球场的特殊性,及地被植物生态习性各异、生长发育开花和休眠期也不尽相同,因此,地被植物可以在更好地满足高尔夫球场功能的同时,形成极为复杂的季相变化,与其它园林植物相比有特殊的优势和更为广泛的用途.     

Children's perspectives on vegetation establishment: Implications for school ground greening

School ground greening might provide multiple benefits for children across age, gender and competence through allowing participation in the greening process and experience of nature and vegetation. However, the process of school ground greening must nurture a positive relationship between children and newly planted vegetation during the first years after establishment. This study explored how green space planning, management and maintenance approaches influence children's school ground use and experiences through a series of field observations following establishment of new vegetation in a landscaped area at a school in Malmö, Sweden. The methods included documentation of vegetation, observations of use and interviews with children and teachers on three occasions during one and a half years following the first planting. The greening approach appeared successful, especially for younger children (up to around 11 years), who were more positive and also used the area more than older children. They also used it for pretend play, which was rare in the school ground before greening. Experiences from continuous participation and physical use appeared important for children establishing a positive and caring relationship with the landscaped area. The results suggest that school ground greening should be well integrated with pedagogic activities. Damage to woody vegetation can be limited by establishing other landscape elements that are attractive for play and by using fences without hindering access.
