Journal of Landscape Research 2017年第4期9卷 37-40,44页

作者： BU Bing CHEN Keshi School of urban Planning and Design Peking University Shenzhen Graduate School

Dafen Oil Painting Village, the largest oil painting village in current China, takes cultural industries like creation and wholesale of oil paintings as the pillar. As one of the urban villages in Shenzhen, Dafen Village not only has the common characteristics of urban morphology as ordinary urban villages, but also has something unique. In this paper, study of the urban morphology of Dafen Oil Painting Village is mainly from 3 aspects: firstly, the formation of street space in Dafen Village; secondly, analysis of the status of urban morphology of Dafen Village; thirdly, the plane layout and public space of Dafen Village. In the end, this paper put forward some suggestions about the future development of urban morphology and space layout in Dafen Village.

Fractal Features of urban morphology and Simulation of urban Boundary

引用

Geo-Spatial Information Science 2008年第2期11卷 121-126页

作者： ZHANG Yi YU Jie FAN Wei School of Remote Sensing and Information Engineering Wuhan University 129 Luoyu Road Wuhan 430079 China 不详

Using fractal dimension to reflect and simulate urban morphology are two applications of fractal theory in city geography. As the only consistent description of a fractal, fractal dimension plays an important role in describing the basic features of fractals. Just like other fractals, our cities have similar characteristics. Fractal dimension to some extent is regarded as an indicator of urban expansion, and it may change with urban morphology in different time and space. Based on the Geographic Information System (GIS), taking Wuhan city as a test area, the fractal dimensions of different land use were calculated, and a linear regression equation was established to analyze the relationship between fractal dimension and residential areas. Then the author used fractal dimension to simulate the urban boundary which is an important part of urban mor-phology. A mid-point subdivision fractal generator is needed in the simulation process, and the shape of the generator is determined by fractal dimension. According to the fractal theory, fractal boundaries in different scales have self-similarity and they have the same fractal dimensions. Based on this fact, the simulation method the author used could quantitatively keep the similarity of configuration of the urban boundaries.

Analysis of urban morphology in Core Towns＇ Neighborhoods of Mexico： Santa Barbara＇s Neighborhood as a Case Study

引用

Journal of Civil Engineering and Architecture 2014年第12期8卷 1575-1584页

作者： Alaide Retana-Olvera Cesar Angel Pena-Salmon Luz Maria Ortega-Villa Faculty of Architecture and Design Autonomous University of Baja California Mexicali B. C. 21240 Mexico Faculty of Human Sciences Autonomous University of Baja California Mexicali B.C. 21240 Mexico

Cities＇ urban morphology is the result of historic, cultural, political and social processes. The historical cores in Mexican cities have high cultural diversity, which also intermingle pre-Hispanic cultures with colonial forms, as well with modernity and post-modernity irruption. The case study is Santa Barbara＇s neighborhood in Toluca City, which was founded in 1524, and the case study was the first neighborhood in Toluca＇s historical core. At present time, this neighborhood is considered as one of the most dangerous places in the city＇s historical core, therefore, it has been abandoned. This paper will display the changes in urban morphology of the neighborhood through the years from 1877 to 2010. For site evaluation, the methodologies of Ashihara （1982） and Lynch＇s （1961） were used in order to analyze positive and negative spaces, as well as main street visual features, street and avenue directions, street circulation and street circulation path configuration. The results show that the focal nodes are a key factor for economic and social reactivation, with which, through urban activation of vacant lots and the traditional use of the streets as public space, is possible to generate centripetal development to restructure the neighborhood.

Effects of urban morphology Changes on Ventilation： Studies in Wind Tunnel

引用

Journal of Civil Engineering and Architecture 2015年第7期9卷 853-868页

作者： Patricia Regina Chaves Drach Gisele Silva Barbosa Oscar Daniel Corbella Post-GraduateProgram in urbanism Federal University of Rio de Janeiro Rio de Janeiro 25645-560 Brazil urban Engineering Program Federal University of Rio de Janeiro Rio de Janeiro 25645-560 Brazil

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.

Review of Global Academics 2014年第2期1卷 205-215页

作者： Chen Zhilong Yang Xiaobin Research Center of Underground Space PLA Univ. of Sci. & Tech. Nanjing Jiangsu

Underground building with such major functions as underground traffic, commerce, culture and recreation, especially the multifunctional underground large-scale public complex, has become a significant part of the overaU functional structure or even the core of a city. Therefore, the expression of the architectural appearance, and characters of underground building, as well as the integration between the building and its external environment constitute an important part in improving overall functional structure and optimizing cityscape. From the perspective of space and environment shaping, the author explores the architectural appearance, and characters of underground building and its external environment, provides several basic design patterns with further discussion.
