A GIS-based Spatial Analysis of Housing Price and Road Density in Proximity to Urban Lakes in Wuhan City, China

As one of the essential urban open spaces, lakes usually contribute immensely to the quality of residents′ daily lives. Different from hedonic approach employed in existing researches on urban open spaces in China, this paper integrates housing price surface with road density to analyze the spatial characteristics in proximity to urban lakes in Wuhan City, China. With the expansion of Wuhan City, urban lakes became polluted, they shrunk or even disappeared, leading to unfavorable conditions for sustainable development of the city. To better understand the spatial relationship between the city and lakes, we classify the urban lakes in Wuhan central area into ′lakes in the urban center′ and ′lakes in urban fringe′. Based on housing price surface we explore the spatial characteristics in proximity to different lakes and differences between the lakes. We also use Geographic Information System(GIS) tool to calculate road density as a supplementary indicator to reflect the accessibility in proximity to urban lakes. The results indicate that relative independence exists between different towns, and the spatial characteristics are different depending on scales and locations. In most of cases, the road density is lower where closer to the lakeshore while the housing price exhibits an opposite pattern. We conclude that city governments and urban planners should give more considerations to these spatial differences, somewhere should be better planned and protected as an important waterfront and somewhere the control of unreasonable real estate development nearby should be strengthened.

An Urban Open Space Extraction Method: Combining Spectral and Geometric Characteristics

This paper introduces an advanced method based on remote sensing and Geographic Information System for urban open space extraction combining spectral and geometric characteristics. From both semantic and remote sensing perspectives, a hybrid hierarchy structure and class organization of open space are issues and mapped from one to another. Based on per-pixel and segmentation mechanism separately, two classification approaches are performed. Owing to prior of spatial aggregation and spectral contribution, the segmentation-based classification exhibits its superiority over a pixel-based classification. Finally a GIS-based post procedure is hired to eliminate some unsuitable open space components in both spatial and numerical constraints on the one hand, and separate open space some fabrics from fused remote sensing classes by defining their Shape Index on the other hand. The case study of Beer Sheva based on ASTER data proves this method is a feasible way for open space extraction.

Research on the effect of the component proportion in the new water mist additive on firefighting performance

Water mist technology provides efficient firefighting performance while there is still room for improvement. So varieties of additives have been studied in recent years both at home and abroad. The self-made additives are used to compare the firefighting performance of diesel and heptane fire in open space. By adjusting the concentration of substance in the additives and conducting the experiment under the pressure of 0.3 MPa,0.5 MPa and 0.7 MPa,extinguish time and temperature are measured in the experiment. Through the experiments using different fuels,it can be found when the fuel is heptane that has a lower ignition point and a higher evaporation rate, the water mist additive can still significantly improve the firefighting performance. According to the data based on different concentrations of fluorinated surfactants,we find that fluorinated surfactants are the main substance to improve the performances by changing physical property of water mist. Optimal proportion of the additives for firefighting performance is found by experiment results.

A new species of extinct genus Lycopodites from Lower to Middle Jurassic sediments of Irkutsk coal basin (Eastern Siberia)

In Jurassic sediments of Siberia, remains of Lycopodites are rare in occurrence. They are represented by two species ： Lycopodites tenerrimus Heer, and L. （.9） trichiatus Pryn. This paper presents an emended diag- nosis of the species L.（.9） trichiatus Pryn., and the descriptions of two new species： Lycopodhes subulifolius sp. nov., and L. baikalensis sp. nov. from the Early-Middle Jurassic sediments of the Irkutsk coal basin, Eastern Siberia, Russia. As part of the research effort, it was found that the ecological preference of the new species was different： Lycopodites subulifolius sp. nov. grew in wet and open spaces, while Lycopodites baikalensis sp. nov. preferred to colonize young growth of bog forests.

Cooling effect of urban parks and their relationship with urban heat islands

It is claimed that open spaces in cities, such as parks, have an urban cooling effect. However, the relationship between urban parks and adjacent districts is still not explicit. In order to clarify the interaction between urban parks and their urban surroundings, this paper takes the Temple of Heaven Park （THP） as an example of a park station and focuses on analyzing the differences with a nearby urban station.THP is located in the center of Beijing, and the nearest urban station is Tian An Men. It is interesting that the cooling effect of THP reaches a peak and remains stable when its city background urban heat island （UHI） varies within a given range, but becomes unstable when the UHI goes beyond the range. This is called an enhanced cooling effect in this paper. As a result, the UHi intensities （UHIIs） are calculated in order to comprehend the role of the park cooling effect in the urban heating characteristics of Beijing. By comparison with five other park-district pairs, this paper attempts to identify the causes of the enhanced cooling effect. It is found that six park-district pairs consistently demonstrate a persistently stronger cooling rate during the night, and that the water coverage might be a key factor in enhancing the park cooling effect. Based on further investigation of the influence of surrounding UHIs on the park cooling effect, it is found that the UHII differences in park-district pairs show quasi-linear changes within a given range as the UHli of the surrounding district increases.

Communities and the Poetic Imaginary：A Folklore Essay on the Poetry of the Wild Project

Poetry of the Wild is an ongoing artistic and literary project that according to originator Ana Flores＇ conception, invites the public ＂out for a walk＂ to freshly experience their world through word, sound, and image. Inspired by birdhouse design, these unique configurations of ＂poetry boxes＂, combining art and poetry are located in various communal open spaces. Each new project solicits a public response from us all to become catalysts for exploring our environs and questioning how a sense of place informs our consciousness. A folkloristic perspective shapes this discussion about the many variations of this collaborative and public project of poetry boxes, installed on trails, in parks, along rivers, and in library stacks over the past ten years. The primary concerns of folklore interpretation such as tradition, identity, cultural creativity, performance, and narrative analysis, are just a few of the dynamics that can be teased out from investigating a project with such interesting cultural parameters. In this context, cultural sustainability and poetic sensibility deepen our understanding of sense of place, environmental aesthetics, shrine markers, and the scope of individual and communal creative action.

Study of the Relationship between Building Arrangement and Visibility of Open Spaces Based on a Simplified Area Evaluation

This paper studies which building arrangement will provide the maximum visibility to an example of open space proposed in the Abu Dhabi 2030 Master Plan. The building forms, the distance between the buildings, the setback and the building heights would all affect visibility and were considered closely. Although this research methodology could be applied to any site in different situations, it remains simple and interesting. It can be applied in general, with a change of the variables （setback, distance between buildings, building height, building form）, to any site by both professionals and students who can simply use any CAD program for producing drawing in both the architectural or urban designs phases, hence the importance of this research. Two different building arrangements were proposed and studied： a linear and an L-shaped arrangement. After applying the simulations, it appears that the L-shape offers more visibility to the open space. The outcomes of this study were combined with another research project that studies the same building arrangements to test the possible climatic comfort provided in outdoor spaces in order to encourage the use of open spaces and walkability in the studied area.

Optimization Design of Open Space Based on Microclimate and Behavior in China

Traditionally, microclimate, behavior and space design are characterized by a separation among climatologists, behavior researchers and designers. It is also unrealizable to apply the research results to the space design because of the gap created by the interdisciplinarity. In addition, although the relationships among space form, urban microclimate and people are intuitively understood, there are still not reasonable predictions on how a space affects the microclimate, and how the microclimate and space will affect people＇s sensation and behavior. By recording the microclimate and people＇s responses, this paper discusses the relationship between people＇s sensation and microclimate as well as people＇s behavior and open space in a busy downtown pedestrian street during hot summer. The research finds that shade plays a crucial role in outdoor comfort. All of the other objectively comfortable and acceptable microclimates differ significantly different shade situation. Simultaneously, space contradiction can be considered an essential factor for spatial utilization. This paper also provides proposal on canyon open space design based on this case study.

Effects of Urban Morphology Changes on Ventilation： Studies in Wind Tunnel

This paper presents study of the effects of urban morphology changes on ventilation dynamics through a comparative study between blocks of Copacabana and Ipanema neighborhoods, located in Rio de Janciro City, Brazil. The study was developed with the aid of experimental simulations in a wind tunnel, taking into account the urban morphology and its relations to open spaces. A diagnosis was produced through the exam of the wind effects in relation to the volume of built and non-built spaces. The effects were classified as positive or negative, in relation to the tropical climate. At first, both blocks studied, one in Ipanema and one in Copacabana, were selected according to common characteristics, which establish a relation between the two regions, such as the distance to the beach and the presence of a public square. The results confirmed our expectations showing Ipanema as a more ventilated area.

Khedivial Cairo： An Evolved Metabolism

Metabolism such as Cairo evolves rabidly, to transform existing urban spaces. The result of transformation process may lead to the loss of the original space qualities. Opera and Ataba squares are junction space which is one of these urban spaces that meanwhile is suffering from this process. This junction space is between two unique urban structures Fatima Cairo and Down town Cairo. This urban structure needs to be a grand civic expression of the 19th century urban system with the new energies of the functionalist city. This Gordian knot of elevated highways, congested surface roads, extensive automobile parking and sprawling informal markets will be integrated into a new open space system that optimizes the city＇s intensified energies. This paper discusses urban structure transformation of the junction space urban structure timeline. Ending with a proposal finally transforms this space into a sustainable urban development.

Improving Open Spaces for a Sustainable City

The feasibility of city living with nature as a way to restore the balance between human uses and natural processes is the focus of this paper about the city of Maringa in Southern Brazil. This urban form, a planned new town founded in 1947 upon a previous, comprehensive British land-development scheme, originally offered a friendly interaction between urban settlement and nature. Hence, this paper outlines how open spaces can be enhanced as an ecological structure, bringing parks, squares, gardens and urban farming into a productive system, both for nature＇s and for people＇s sakes. Following a morphological study, the proposed ecological structure will maintain ecological processes within the urban grid and help to preserve historical and social values, by linking a wide variety of natural and restored ecosystems and landscape features. The adoption of this kind of ecological planning will certainly result in an increase of the urban landscape quality, changing actual planning paradigm and preventing the city from environmental quality decrease.

Morphological and Structural Categories： Geometric Attributes of the Form of Places

The author knows how to interpret the city is a complex task that met the physical form and also all the images that are transmitted by the sensations. However the aim of this paper is to demonstrate the importance of studying the morphological categories, using the geometric attributes of the shape of places, facilitating the development of three-dimensional view of the architects, in particular for students of architecture. This article is part of the Project ＂Education of the Eye＂ which introduces the training of the eye as a strategy to understand the architectural forms characterizing the volumetric space （architectural, urban and landscaping）, through the polyhedra and their relationships. It is linked to the research line Teaching of Architecture Graduate Program in Architecture -- PROARQ-FAU/UFRJ. The investigation of the way in this direction, interacts with the knowledge produced by the groups SEL-RJ -- Research Group on Systems of Open Spaces in Rio de Janeiro, ProLUGAR -- Design and Quality of Place and EAG-Education-Environment Group.

Accessibility and Integration Study of Part of the Abu Dhabi 2030 Master Plan by Using Space Syntax

This paper studies the accessibility of open spaces and facilities and the integration of streets to the whole urban system of the Emirati neighbourhood of the Business District of the Abu Dhabi 2030 Master Plan. For this purpose, axial lines were produced by applying space syntax theory, Depthmap software. The research aims to verify the location of open spaces and facilities, such as schools, in relation to the location of public transportation stops （bus, metro and tram）, in order to check their accessibility within walking distances. The objective is to pay attention to the relationship between land use and transportation in the planning phase for future interventions or proposals, in other words, to improve the accessibility of public spaces or buildings by pedestrians in order to comply with the vision of the Abu Dhabi 2030 Master Plan and its promotion of walkability and cycling. Although many measures will be taken at the scale of urban design to provide shaded open spaces and sidewalks, saving pedestrians from walking long distances shall be done in the planning phase, the challenge remains to create a micro climate to increase the ease of walking in the heat and decrease dependence on cars for mobility.

Potentials of a Place as Leaders for Prioritizing the Adjustment of Public Spaces within a Hierarchy

The article gives a view over a part of a research that has been started on public spaces as a shared wealth of different qualities and uses. Introduction explores the capital of Slovakia a little bit in the sense of urban structure and historical consequences. The issue is currently solved by several members （academics, officials, NGOs （non-governmental organizations）） focusing on the same thing from slightly different aspects. Therefore, qualities and characteristics of an open space are put into closer look in the main text body part. Single tools working with individual features describe the up-to-date situation in the Bratislava city center. It is assumed that they could be used for whole city and other cities as well, what would bring an overall look at towns and cities in Slovakia. Features and findings are expressed in map and in simplified graphic schemes. Findings include mutual effects and consequences between role of a space in the city as a cultural phenomenon, its physical surrounding and people flowing daily through it. Finally, advices and prioritization could be formed for the city itself as a self-governing subject to improve its ＂inner-outer＂ qualities.

Redefining/Reconstructing the ＂In-between＂： An Urban Transformation Scenario for the Haydarpasa Harbour, Istanbul

Istanbul as a ＂third world＂ metropolis is a dynamic open system, where complex and multiple economical, social and physical conditions are overlapped. Still the city is a focus point of social （economical, cultural, and ethnical） and spatial dualisms and their genuine contradictions--polarizations particularly in the last 30 years. Istanbul＇s natural characteristics such as geographical conditions （slope topography and the physical relationship with the sea）, and also the artificial urban properties that include the historical architectural monuments, the industrial heritage, the contemporary urban transformation applications, the harbours and docklands as borderlines or in-between zones also identify this fragmented, hybrid, and divided urban structure. The Haydarpasa Harbour as an artificial urban borderline between the ruined and peak zones lJskudar and Kadikoy on the Asian side of the city is a kind of representative in-between area, an isolate city in city, which triggers the social and physical collage and ＂deconstructs＂ the development process of lstanbul＇s morphology. This paper aims to analyze these social and spatial aspects, which endure urban polarization in Istanbul. The underlying reasons of these contradictions and eventual outcome of the peak and the ruined zones in lstanbul and their border districts typologies will be analyzed. This paper will also make a compared evaluation of Haydarpasa Harbour （intersection point of two adjacent districts in Istanbul） and the completed urban design transformation projects/scenarios on the harbor area regarding the creation of a sustainable urban development for the city by enabling a new productive public space in-between [Jskudar （＂ruined＂ zone） and Kadikoy （＂peak＂ zone） in Istanbul.
