For the urbanization, more land inside or around the limited cities have been exploited at the expense of greenery to build buildings as well as infrastructure to satisfy the according demands caused by urbanization. But human beings can never live without greenery, and more citizens mean more needs on greenery. In view of this, the importance of greenery has been increasingly recognized by urban planners and policy makers. This essay aimed to explore the role that greenery plays in urban planning in modern Britain and provided the theoretical basis for better utilization of greenery in the future urban planning.展开更多

Ontology is one of the most important classification schemes that aim to make data machine-interpretable. In the literature, all ontology based models developed in the field of urban planning have some limits. First, they describe the nature of each parcel of the soil while ignoring other important components of urban planning such as services, infrastructure … Secondly, these ontologies are developed according to legislation and regulations of the zone studied so they can’t be used by some urban territories that have specific urban law such as Moroccan country. This paper presents a new multi-dimensional ontology model called LUP specifically developed to overcome this flaw. The main goal is to provide semantic land use descriptions according to four dimensions: zoning, services, infrastructure and easement and to define all LUP concepts within the Moroccan urban law. We illustrate the use of our proposed model with a case study by mapping a land use planning document within the area of Ainchock municipality of Casablanca city according to our model concepts.展开更多

The urban perimeters of municipalities have been used increasingly in favor agents of the reproduction of unequal urban space, aggravating the process of socio-spatial segregation, the formation of urban gaps and real estate speculation. Inherent to this process, infrastructure, one of the most important components of urban land and one of the most costly for local governments, has become increasingly dispersed and obsolete in the midst of the disordered occupation of the city’s land. Based on the above, this paper aims to analyze the phenomenon of urban sprawl in the city of Londrina by means of geotechnologies and to identify the impacts that the form of land occupation the city has employed may cause on the current and future scenario of the municipality in general. To this end, thematic maps were drawn up from multiple sources, which, allied to a review of the literature, indicate that the municipality of Londrina exhibits intense characteristics of the phenomenon of urban sprawl, leading to consequences for territorial ordering and the egalitarian spatial distribution of essential services to the population.展开更多

Traditional studies of the external environment of human settlements, however, frequently overlook the combined impacts of wind and snow environments. Furthermore, in urban meteorological studies, it is impossible to accurately assess the wind and snow environment in specific areas or locations. In this study, a refined Computational Fluid Dynamics(CFD) multiphase flow numerical method was used to simulate a planning space's wind and snow environment. The study classified the Snowstorm Weather Grade(SWG) by incorporating the Snowstorm Weather Index(SWI) to generate calculation results of the wind environment and snow environment. In particular, 150 measurement points in the planning space were chosen for analysis and evaluation of their wind and snow environments. The results demonstrated that the SWI index can effectively correlate to the wind and snow environment calculation results. In addition, the graph of SWI showed that 55% of the measurement points had a moderate wind and snow grade SWI, which exceeds the average grade for the entire region. The practical application shows that the wind and snow environment assessment indexes and technical methods developed in this paper can be successfully applied to wind and snow environment studies in other cold cities.展开更多

This research is pivotal as it showcases that GIS technology is not just a tool for mapping, but a critical component in urban planning and emergency management strategies. By meticulously identifying and mapping flood-prone areas in Midar, the study provides invaluable insights into the potential vulnerabilities of urban landscapes to flooding. Moreover, this research demonstrates the practical utility of GIS in mitigating material losses, a significant concern in flood-prone urban areas. The proactive approach proposed in this study, centered around the use of GIS, aims to safeguard Midar’s population and infrastructure from the devastating impacts of floods. This approach serves as a model for other urban areas facing similar challenges, highlighting the indispensable role of GIS in disaster preparedness and response. Overall, the study underscores the transformative potential of GIS in enhancing urban resilience, making it a crucial tool in the fight against natural disasters like floods.展开更多

It argues that, within the current public participation framework, neither the "bottom-up" active participation nor the "top-down" passive participation can generate satisfactory effects or mediate multiple interests, whereas a professional third party could effectively promote public participation by bridging the public with the government. Besides, the third party plays an increasingly significant role in maintaining public interest, particularly in a context where the government often overemphasizes economic interests and there is a ubiquitous lack of awareness among the general public.展开更多

文摘Taking the Enning Road Neighborhood Renovation Project in Guangzhou as a case, the paper aims to illustrate, based on the materials collected from interviews and news media, the dilemma of public participation in China's urban planning, as well as the role of a third party in urban planning. It argues that, within the current public participation framework, neither the "bottom-up" active participation nor the "top-down" passive participation can generate satisfactory effects or mediate multiple interests, whereas a professional third party could effectively promote public participation by bridging the public with the government. Besides, the third party plays an increasingly significant role in maintaining public interest, particularly in a context where the government often overemphasizes economic interests and there is a ubiquitous lack of awareness among the general public.
文摘Since the eighties, the development of China’s urban planning work has ev-er been keeping pace with the progression of China’s reform and opening to the outsideworld. Every high tide of reform and opening to the outside world has become the boom-ing period of city planning work development. After the southern investigation tourspeech of Mr Deng Xiaoping this year, again a new high tide of reform and opening to theoutside world has emerged in our country, our city planning work have also entered a newgolden stage. From the achievements of China’s city planning work in recent years, sever-al trends mentioned below are significant.
