山地城市交通受地形起伏变化限制，形成了道路护坡、隧道口堡坎护坡和立交桥附属空间等大量具有立体属性的附属绿地。这些附属绿地多以立体绿化形式呈现，它们是改善城市景观、彰显城市特色和提高人居环境质量的重要内容。本研究正视国内山地城市立体绿化经验相对不足的现状，以重庆市主城区典型交通附属绿地立体绿化为研究对象，基于实地调查，归纳总结出其植物配置欠佳、景观功能单一、养护管理缺失等问题，并从提升生态效益、丰富景观功能、增强景观品质等方面提出了具体改进建议，以期促进山地城市交通附属绿地立体绿化的可持续发展。 相似文献

城市规模的快速扩张引发人口剧增,导致车辆暴增,为了缓解交通压力,各大城市纷纷上马立交桥工程。人们解决了温饱问题后开始对生态环境也日益关注,这些立交桥就成为城市扩大重直绿化空间的重要载体。立交桥的绿化景观既能吸收车辆排放的尾气,改善生态环境,增加城市碳汇,还能给人们带来无限美好的视角享受。然而,立交桥的绿化工程面临着给排水方面的诸多困扰,严重影响了绿化效果,增加了绿化养护的成本。本文重点分析了城市立交桥绿化的给排水难题,对研发的两项专利技术在桥梁绿化给排水工程中的应用进行了论述,希望能为城市化进程中立交桥绿化设计提供参考。 相似文献

近年来,城市绿化愈加成为城市美化的重要一部分内容,以立交桥、硬质挡墙立面为绿化区域也逐渐从研究落实到当前的城市绿化当中。以立交桥、硬质挡墙立面为绿化区域能够有效扩大城市绿化的空间,是太原市垂直绿化工作的一个重要方向。本文通过对于当前的太原市立交桥、混凝土挡墙等构筑物垂直绿化的相关重点进行解析,借此希望能够对太原市立交桥、混凝土挡墙等构筑物垂直绿化起到一定的参考作用。 相似文献

The information of urban tree species resources is of vital significance to the planning and design of urban green spaces. Tree organs, such as the bark are used as the primary features of identifying tree species. However, traditional tree identification methods need to consume a lot of manpower and time costs. In addition, the application of machine image recognition technology to tree species recognition still has problems such as heavy data preprocessing workload, small number of tree species images, uneven distribution of categories, and low recognition accuracy. In order to promote the intelligent management of urban forestry and solve the above problems, it is necessary to establish an automatic image recognition model for urban greening tree species. We captured bark images of 21 urban afforestation tree species in their natural environment and constructed a dataset that was divided into a train set, validation set, and test set in the ratio of 7:1:2. Combining Channel Attention Module (CAM) with algorithms such as Spatial Pyramid Pooling (SPP) and Mixed Depthwise Dilated Convolutional Kernels. The core algorithm is Mixed Convolution Kernel (MK), and a CAMP-MKNet Convolutional Neural Network (CNN) is constructed as a bark image classification model for urban greening tree species. The overall accuracy of the generic models ranged from 41.06% to 82.03%, whereas the overall accuracy of the experimental CAMP-MKNet model was 84.25%, with lower prediction cost. Our study shows that the CAMP-MKNet CNN model with better prediction performance and computational cost and can provide crucial insights and technical support for developing automated urban tree species image recognition systems. 相似文献

The creation of green rooftops is an important method for mitigating heat build-up in urban rooftop environments because they lower the sensible heat flux over the rooftop and conductive heat flux into the building. We propose a model for assessing thermal mitigation effects through a hydroponic urban greening system based on heat balance. We conducted an experiment with two different rooftops at two study sites, which were monitored for two months in two different years. Each rooftop was divided into two areas: one bare, the other covered by the hydroponic urban greening system. Parameters measured in both areas were air temperature, surface temperature, and conductive heat flux. The data were analyzed using three thermal mitigation indices. However, it was difficult to show a uniform relationship between the latent heat flux and mitigation indices during the period of analysis. This suggests it would be necessary to include factors such as latent heat flux, conductive heat flux, and water heat storage flux to assess the thermal mitigation effect. Our research indicated that the composition of heat balance terms could estimate thermal mitigation effects in the green roof area independent of the year. The results suggest a principle for assessing the mitigation effects of urban greening on the thermal environment. 相似文献

Globally, there is growing recognition of the potential of road verges to contribute to urban greening and ecosystem service provision, beyond their original functions of utility provision and public access. Numerous, diverse stakeholders are involved in their management, yet their shared and diverging perspectives on verge greening are poorly understood. This research examined the perspectives on road verge greening by 30 respondents from eight stakeholder groups from the Perth Metropolitan Area, Australia. Stakeholders spanned local and state governments, developers, peak bodies, utility providers, environmental consultants, verge treatment providers and urban greening advocates. Semi-directed interviews and Likert scales were used to assess respondents' perspectives and perceived importance of urban verge functions and ecosystem services, risks and challenges associated with verge greening, and preferred verge vegetation composition. The most important ecosystem services for all stakeholders were temperature regulation (through the provision of street trees), those associated with water management and aesthetically interesting streetscapes. Perceived challenges included limited knowledge for the management of native species verges and streetscapes, organisational costs for verge managers and utility providers, and the need to engage with multiple local government authorities with widely varying management and financial valuation of verge vegetation. Stakeholders’ preferred verge reflected diverse uses, local characteristics, and was climate and water resilient (particularly ‘waterwise’). A majority of stakeholder groups felt greater attention to the ‘understorey’ of the ‘urban forest’ was warranted. An emerging perspective across four stakeholder groups identified the potential for verges to grow a local ‘sense of place’, through plantings emphasising local native species and highlighting local Whadjuk Noongar seasons. These findings support policies and programmes associated with urban greening, and assist in navigating the contestation often associated with new or transformative uses of land at the public-private interface. 相似文献
