As a consequence of the large deficit between the annual housing demand and supply, squatter housing construction was the major means for shelter of low income families who can not have their place in the housing market as buyers. Squatter houses are located either on the peripheries of the cities or mostly outside of the urban boundaries on public land or illegally subdivided land by creating many physical, social and environmental problems. After 1990's, depending on the globalisation wind and neo-liberal policies that enriched the new elites who have new life styles, the housing capital focused on these group. After 1999 earthquake in Turkey, the fear of possible earthquake has also changed the housing preference as from the high-rise apartment buildings to the lower detached houses. As a consequence of this supply-demand chain, the private housing investment was directed to the gated communities which are isolated settlements with restricted access, so that public spaces are privatised or their use is prohibited or controlled on the edge of the metropoliten cities. These settlements also have physical and social problems. This paper will analyze the change of urban periphery, location and relation with the natural thresholds and the main transportation system of these settlements of Turkey in the light of literature review and some development plans and interview with real estate developers and users.展开更多

In a...Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.展开更多

As a consequence of this supply-demand chain, the private housing investment was directed to the gated communities which are isolated settlements with restricted access, so that public spaces are privatised or their use is prohibited or controlled on the edge of the metropoliten cities. These settlements also have physical and social problems. This paper will analyze the change of urban periphery, location and relation with the natural thresholds and the main transportation system of these settlements of Turkey in the light of literature review and some development plans and interview with real estate developers and users.
文摘At present,many scholars at home and abroad have put forward classic theoretical knowledge about interactive installations,but the application research of interactive installations in urban landscape design is relatively vague.Moreover,most of them focus on the research of individual interactive installations without taking the surrounding environment into consideration,and there are few targeted researches on the application of interactive installations in landscape design.In this study,through the investigation on interactive forms and implementation methods of interactive installation intervention in urban landscapes,as well as domestic excellent cases,we discovered the existing problems of interactive installation intervention in urban landscape design and put forward our own opinions on future development.

文摘Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives.
文摘"Digital City" has gradually emerged,promoting the digitalization of urban landscape design,and meanwhile,virtual reality (VR) technology allowing us to create and experience the virtual world has come into reality.The use of VR technology in the urban landscape design,and interactive 3D dynamic view,multi-source information fusion and system simulation of the entity behavior will be beneficial to generate the simulation environment of urban landscape design on the computer,and guide the scientific development of urban landscape design.On this basis,this article analyzed the connotation of VR technology and basic characteristics of urban landscape artistic design based on the overview of previous studies on the urban landscape design in multiple aspects,and further explored the application of key technology in the VR-based simulation of urban landscape artistic design,to provide the reference and idea for urban landscape design,and improve overall effect of urban landscape artistic design.
