为了有效加快城市园林绿化建设的脚步,传统的季节种植技术已经无法满足城市园林绿化建设的需要,城市园林建设开始打破植物生长的正常规律,以反季节种植技术来提高植物的成活率,进而加快城市绿化速度,提高城市环境。通过反季节种植技术在2018年丰台区"留白增绿"项目绿化施工中的应用,对反季节种植技术的概念以及应用原则进行了介绍,用实践总结反季节施工技术要点。 相似文献

“森林城市”模式与城市绿地园林景观及功能的弱化 总被引：2，自引：0，他引：2
“森林城市”的提法导致城市园林绿化建设模式产生一定的偏差，“森林城市”忽视了城市内绿地与城市外绿地功能的诸多差异，甚至导致城市园林绿地丧失其应该体现的园林艺术特征和休闲、游憩、娱乐、健身等综合功能。除生态效益之外，只有强调城市绿地的园林艺术特征和多功能性才能防止城市绿化中过密、过滥的“森林式”的种植模式。正确定位城市中心和城市外围两种不同地域绿地的功能和结构，并以生态的楔形绿地为桥梁是实现城内外绿地相互联系、功能互补的一个有效途径。 相似文献

Associations between green space,air pollution and birthweight in Sydney Metropolitan Area,Australia
Growing number of evidence have reported that exposure to air pollution was associated with unfavourable birth outcomes while increased exposure to green spaces was associated with better birth outcomes. However, the effect of interactions between air pollution and green spaces on pregnancy outcomes remain unclear. Using the data on all the live births recorded in Sydney between 2016 January and 2017 December, we built up multilevel linear and logistic regression models with random intercepts for statistical area level 2 (SA2) to examine the association between residential levels of air pollution (NO2, PM2.5, SO2 and O3) and pregnancy outcomes including birthweight, low birthweight, and preterm birth. This was followed by assessment of potential effect modification by green space quantity by fitting 2-way interaction term between each air pollutants and green space quantity separately. Furthermore, building on the 2-way interaction term, we explored 3-way interactions by adding area level socio-economic status and population density. Higher levels of PM2.5, NO2 and SO2 were statistically significantly associated with decrease in birthweights (p < 0.05) in the adjusted models. We observed statistically significantly association between the lower risks of preterm birth and higher levels of NO2 in the adjusted models (p < 0.05). However, none of the other air pollutants were statistically significantly associated with the odds of low birthweight and preterm birth. In the adjusted models, green space quantity was statistically significantly associated with reduced odds of preterm birth (p < 0.05). The results for birthweights were in the same direction (p < 0.05) however, some of these associations did not remain statistically significant after adjusting the models for air pollution. In general, no associations were found for low birthweight. Statistically significant 2-way interactions between green space quantity and NO2, PM2.5 and SO2 levels indicated that association between moderate levels of NO2, PM2.5 and birthweight weakened in the greener areas (>20 %) especially in the affluent and densely populated areas while the effect of SO2 did not differ consistently across green space levels with benefit of exposure to the greenest areas (>40 %) was evident, yet not statistically significant. Our findings suggest that increasing green spaces in cities may help supporting a healthy start in life by decreasing harms of moderate levels of air pollution. Replication in different contexts and consideration of potentially contrasting results with different types of green space is warranted. 相似文献

城市化进程导致热岛效应加剧,三维绿量对城市绿地的热环境效应有显著影响。利用2020年9月太原市Landsat 8遥感影像,结合样地三维绿量实测数据,借助遥感及GIS技术,建立太原市三维绿量反演模型,测算太原市城区三维绿量,分析其绿量分布格局;同时利用针对Landsat 8 TIRS第10波段的单窗算法(TIRS10＿SC)反演太原市地表温度,探讨城市绿地三维绿量对热环境的影响作用。结果表明：(1)太原市北部、西南及东西两山植被覆盖较好,三维绿量高,城市中部硬质半硬质区域三维绿量低,城市公园作为高绿量节点镶嵌于城市中部;在绿地空间结构上,乔木层平均树高对三维绿量的影响较大,二者的关系模型为Y=469.912x+936.466。(2)三维绿量与地表温度呈显著负相关,二者的关系模型为Y=5.828x-0.029,三维绿量较小时,降温趋势显著,随着三维绿量不断增大,降温趋势渐缓;绿量密度在5～18 m3/m2之间的乔灌草或乔草复层配置能较好地发挥降温效果。(3)三维绿量的空间分布对地表温度有一定影响,绿量密度高、连通性高,具有稳定大面积斑块的区域,其地表温度低,降温效果好;相反,绿量密度低、破碎度高的区域,其地表温度高,降温效果差。 相似文献

Compared with public parks, residential quarter green space (RQGS) is a type of enclosed private green space that is located in residential areas and has higher visit frequency. Generally, in China residential areas with high housing prices have higher quality and more quantity of RQGS. Therefore, the differences in RQGS between residents with different socio-economic status may influence the equity of urban green space accessibility. However, due to the lack of data sources, few existing studies have taken RQGS into account as a part of urban green space supply resources. Based on multi-source geographic big data, this paper takes Shenzhen as the research area to explore the impact of RQGS on the spatial pattern and fair distribution of green space accessibility. The total green space accessibility (TGSA), which includes the accessibility of RQGS, and the public park accessibility (PPA) were calculated using the Gaussian-based two-step floating catchment area method (2SFCA). Using housing prices to indicate the income level of dwellers, bivariate Moran’s I and multiple regression were adopted to explore equity of urban green space accessibility. The main conclusions were: (1) The accessibility of green space increased by 27.97% on average after considering RQGS and ignoring RQGS could underestimate the accessibility of green space, particularly in the residential quarter with high housing prices near the city center. (2) The regression coefficients of housing prices with PPA and TGSA were 0.042 (p < 0.01) and 0.160 (p < 0.001), respectively, indicating that the advantages of high-income groups in RQGS may further exacerbate the inequity of urban green space accessibility. The research conclusions may provide a scientific basis for optimizing the spatial structure of green space in urban areas and ensuring the equitable distribution of green space. 相似文献

There is increasing awareness of the benefits of campus green space in promoting student's health. However, information on how campus green spaces benefit students’ health is insufficient or limited to guide the planning or management process. As a result, the present study collected 897 valid responses to examine the differences in campus green space usage patterns among students with varying individual characteristics and to assess the interrelationships between students’ socio-demographic characteristics, perceived naturalness, patterns of use, and self-rated restoration and health using a structural equation model. The findings indicated that there were gender disparities in the presence of companions and frequency of use of campus green space, as well as discipline differences in companion presence. Additionally, gender, age, and discipline had distinct associations with perceived naturalness, patterns of use and self-rated restoration and health. Perceived naturalness positively contribute to patterns of use and self-rated restoration and health, while the frequency of use positively contributed to self-rated restoration and health. Moreover, students’ perceived health can be improved in part through the mediating effect of the self-rated restoration. The study findings demonstrated how campus green spaces benefit students’ health and provided valuable information for campus green space managers and designers. Therefore, we propose that presenting diverse natural elements, manipulating them in natural forms, providing feelings of wildness or friendliness, and eatablishing vast, high-quality, and diverse green spaces to promote students’ health. 相似文献
