Application of CITYgreen5.0 model to tender appraisement of small-scale green-space designs

Developed by the American Forests, CITYgreen5.0 model has been widely applied to urban forestry research and has played an important role in analyzing quantitatively the ecological benefits produced by varied green-space ecosystems. One of the functions of this model is to evaluate quickly and objectively on parts of the ecological benefits possibly produced by different design schemes for the same small-scale green-space project before the establishment. A comparative analysis was conducted by modeling partial ecological benefits potentially produced by green-spaces of two different design schemes for the same roof garden of Chuangfushidai-Junjingyuan in Shenzhen, given the growth status of plants both immediately after the establishment and 20 years later. Meanwhile, the project costs for each design scheme were also taken into consideration. The results showed that scheme II, mainly designed with a natural style of plant disposition, had a better greenery structure than that of scheme I, which was basically designed with a regular style of plant disposition. The estimated value of the partial ecological benefits produced by scheme II was larger than that of scheme I and the benefit-cost ratio of scheme II was more rational. It was suggested that scheme II be put into practice.

Urban Planning and Greening Practices: A Case For Neighborhood Development in a Typical Urban Area

The work that follows aims at evaluating the urban area/neighborhood of“Agios Konstantinos”in the city of Larissa to the extent that it meets the criteria of green-sustainable design,as these criteria are included in the LEED-Neighborhood Development system methodology.The above methodology encodes the most important elements for green urban planning and provides a quantitative assessment system with key axes those of“smart location and connectivity”,“neighborhood model and plan”and“green infrastructure and buildings”.Nowadays,there is an ongoing debate on urban space and its problems.All urban elements,such as those of the built-structured environment,its open-public areas and its natural elements formulate the urban plot.At the same time,human activities greatly affect both the plot and the living conditions.Environmental issues are often disregarded in urban space and its planning process with damaging effects on cities and,more general,on urban settlements.The advantages and benefits of formally including environmental considerations in urban planning and integrating them into urban development strategies are many,as two of the most important“urban problems”are those of the gradual deterioration and degradation of the area’s microclima and the excessive consumption of energy resources.

The conservation of city green space includes a sound plan of green space and the non-statutory parks and green open space, which are open spaces of both public and private land to be greened, they both become the basis for constructing an ecological green network of great city environment. To manipulate cross-sectoral integration, the city greening practice performs effective implementation. The main objective of an approach is to perform the governance indices of green spaces by expert questionnaire and then draft the greening strategies for Taipei city to improve the green landscape and the quality of city environment. The research draws on the green infrastructure and green ecological network system, analyzes the green ecological resources and the characteristic and structure of city spaces in Taipei city, in the meanwhile, learns the domestic and international experiences of greening development. By means of city green space of activation transformation and program of action under greening performance, Taipei city promotes the green image and the quality of city environment and green city landscape.

Research on the Development of Modern Environment Art Pattern under the Perspectives of Green City and Environmental Protection

In this paper, we conduct research on the development of modem environment art pattern under the perspectives of green city and environmental protection. Environmental art and practical function refers to the practical use of it, fitness for a particular purpose or use value, is also the most concern of the basic user. Practical function is the most basic level in the environmental art design, environmental art and practical function and the traditional social system, history, ethnic customs, science, culture, economic development level, and there is a close relationship between geographical environment and so on. Environmental art including landscape and soft landscape two kinds big. Soft landscape plant configuration and plant layout as the main content, hard landscape sketch facilities including floor, ground shop, and environment and therefore, environmental art and practical function mainly reflects in the hard landscape design, the environment landscape facilities to provide practical purpose or use value. Our research proposes the related new idea that is meaningful.

Learning-based Green Workload Placement for Energy Internet in Smart Cities

The Energy Internet is a fundamental infrastructure for deploying green city applications, where energy saving and job acceleration are two critical issues to address. In contrast to existing approaches that focus on static metrics with the assumption of complete prior knowledge of resource information, both application-level properties and energy-level requirements are realized in this paper by jointly considering energy saving and job acceleration during job runtime. Considering the online environment of smart city applications, the main objective is transferred as an optimization problem with a model partition and function assignment. To minimize the energy cost and job completion time together, a green workload placement approach is proposed by using the multi-action deep reinforcement learning method. Evaluations with real-world applications demonstrate the superiority of this method over state-of-the-art methods.

China＇s Sponge City construction： A discussion on technical approaches

Since 2014, China has been implementing the Sponge City Construction initiative, which represents an enormous and unprecedented effort by any government in the world for achieving urban sustainability. According to preliminary estimates, the total investment on the Sponge City Plan is roughly 100 to 150 million Yuan （RMB） （$15 to $22.5 million） average per square kilometer or 10 Trillion Yuan （RMB） （$1.5 Trillion） for the 657 cities nationwide. The Sponge City Plan （SCP） calls for the use of natural processes such as soil and vegetation as part of the urban runoff control strategy, which is similar to that of low impact development （LID） and green infrastructure （G1） practices being promoted in many parts of the world. The SCP includes as its goals not only effective urban flood control, but also rainwater harvest, water quality improvement and ecological restoration. So far, the SCP implementation has encountered-some barriers and challenges due to many factors. The present paper presents a review of those barriers and challenges, oftizrs discussions and recommendations on several technical aspects such as control goals and objectives; planning/design and construction of LID/GI practices; performance evaluation. Several key recommendations are proposed on Sponge City implementation strategy, Site-specific regulatory fi＇amework and technical gmdance, Product innovation and certification, LID/GI Project financing, LID/G1 profcssional training and certification, public outreach and education. It is expected that the successful implemen!atiun of the. SCP not only will bring about a sustainable, eco-friendly urbanization process in China, but also contribute enormously to the LID/Gl research and development with the vast amount of relevant data and experiences generated from the Sponge City construction projects.
