One of the important features of urbanization is the replacement of the original natural soil and vegetation by impermeable pavements, resulting in the changes of the permeability of natural soil and vegetation and bringing a series of ecological future trouble. Since the hard urban pavement occupies a considerably percentage of the whole area, its ecological environmental effect plays a very important role in the overall ecological environment of the city. As a result, the application of permeable pavements is an effective way to solve the problem of urban pavement ecological environment. This paper analyzed the environmental benefits of the permeable pavement and proposed the principles and technical measures about ecology regression of pavement. The measures contain maintaining the permeability of the water penetrate paths, establishing the criterion of the design and construction for penetrative pavements, improving the maintain technologies and so on.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

At present, the cumulative coal gangue piles up about 4.5 billion tons and annual discharge capacity reaches 300 million tons in China. Emissions of coal gangue wastes national resources and will take up a lot of land. Besides, the ecological environment will be polluted and damaged. Using coal gangue as roadbed filling material can not only solve the difficulty of land expropriation, but also consume a large amount of accumulated coal gangue, which has huge economic and environmental benefits. Through laboratory soak test and leaching test, this paper analyses the inorganic salt content and heavy metals of coal gangue used in Xing Fen expressway. Groundwater in Xing Fen highway was captured, detected, evaluated and its quality was good or excellent. In this project, the effects of coal gangue on groundwater meet the regulatory requirements and coal gangue as a new filler can be applied to coastal highway roadbed.

Medan City is currently designated as one of the 20 national tourism destinations that implement Sustainable Tourism Development (STD) in Indonesia. The commitment to implement STD nationally is marked by the signing of the text of the Memorandum of Understanding (MoU) of 20 Regional Heads who are committed to implementing STD together with the Indonesian Ministry of Tourism. Furthermore, under the supervision of the Republic of Indonesia Ministry of Tourism, 20 existing Regencies / Cities made various improvements in each region so that they were finally eligible for STD certification from the STD international certification body. Medan City itself, through the Medan City Tourism Office, related to the implementation of the STD, has established a number of leading tourism destinations. It is hoped that in the future, Medan City will have tourist destinations that have received STD certification. This research was conducted to formulate a model of implementing sustainable tourism development in Medan with a total sample of 220 people spread over 11 leading tourist destinations in the city of Medan, samples were taken with a purposive random sampling technique. The research variables used include; sustainable management, socio-cultural benefits, economic benefits for the surrounding community, environmental benefits and the application of sustainable tourism. Data analysis was carried out with a structural model of the Structural Equation Model (SEM) with the help of Amos 22 software. The results showed that the management aspects, economic aspects, socio-cultural aspects of environmental aspects, and the impact of tourism, directly and indirectly, have a positive effect on the implementation of sustainable tourism in the city of Medan.

PurposeUrbanization is characterized mainly by changes in land use and conversion of natural areas into built environments, as well as by a series of impacts, such as loss of biodiversity, which interfere with the proper functioning of ecological networks.Design/methodology/approachThus, the authors apply a bibliometric analysis using the term “Urban Trees” in the “Web of Science” database, between 2009 and 2019, as a keyword to include all urban green structures and identify the main aspects of urban ecological relationships. They found 8,367 published articles.FindingsThis review identified the main countries and research institutions that operate in urban afforestation. In general, developing countries seek to understand the environmental benefits that urban afforestation can provide, demonstrating the importance of maintaining existing green areas in urban centers to promote the balance of the ecosystem. It depends directly on the flow of ecosystem services provided by green infrastructures in the city, contributing significantly to carbon sequestration, retention of particulate matter, mitigation of heat islands and reduction of surface runoff, directly favoring the health and well-being of the population. The authors conclude that the actions currently implemented in urban afforestation, especially to increase the richness and abundance of species, will be decisive for the future of urban centers and the construction of more sustainable and egalitarian cities.Originality/valueThis work sought to develop a bibliographic research based on information obtained by bibliometric analysis that has the ability to identify trends and volumes of scientific production in a given area of knowledge.

This chapter establishes the book’s key theoretical premises, including capitalist cycles of crisis and resolution (Marx), double-bind theory (Bateson), the spatial fix (Harvey), and capitalism and schizophrenia (Deleuze and Guattari). Using New York City as an example, it discusses how city leaders resolved economic crises through the continual exploitation of natural and human resources. The constant remaking of urban neighborhoods fueled the city’s economic engine, especially as the city shifted to a real estate-based economy. Towards the end of the twentieth century, this real estate imperative coincided with increased public concern about the dangers of climate change. The broad appeal of sustainability provided the perfect cover for Mayor Michael Bloomberg’s neoliberal agenda to recreate New York as a luxury city. But just as Bloomberg’s emphasis on private industry intensified the gap between the city’s rich and poor it also unevenly distributed environmental benefits and burdens.
