  • This paper uses 192 urban data in 1990-2005, and Carlino model, estimate urban agglomeration economies, that is urbanization economies. The results of estimation of urban agglomeration economies suggests that the h value of 145 urban bigger than 1, and h value of 47 urban smaller than 1, that is most of urban has the positive urbanization economies. But the regional disparity is serious, Eastern region's urban agglomeration is obvious, and North-eastern region's urban agglomeration economies is not obvious, appears urban disagglomeration economies. For analyzing the relation between urban agglomeration economies and urban scale, this paper tested the function of urban agglomeration economies. The results suggests that urban agglomeration economies and urban scale has not the inverse U-type function.

  • The very problem we are to touch in this study is that our own types of urban housing complex are isolated from the existing residential environment. The closed and self-completing structures of past urban housing complexes didn't develop the communal spirit and it has increased anti-city trends. With all that, this study intends to provide some materials to reform our urban housing environment through analyzing former European examples on the basis of the development of our own urban housing types which will correspond with existing urban structure and urban tissue.

  • This paper discussed the use of the urban greening space beside nature land----special sites of urban Greening. Consider: the special sites of urban greening are referred to the space formed by urban building and framing, where plants can grow under natural or artificial condition. Filly using those spaces will efficiently increase green area, improving ecological environment and landscape in urban area. A classification to special sites of urban greening was put forward, which are the habits of plant combine with the form of buildings. The present status and future trends on urban greening at special sites was discussed and analyzed. Consider: there are two developing trends of the research of urban greening at special sites. Firstly, it is more naturalize and ecologize greening landscape. Secondly, It will take form a techologize in the process of constructing and materials.

  • This research aims at exploring the relationship between urban greenery and urban landscape and thereby deriving proper planning indicators of urban landscape, For the purpose, this research used survey research method which asked urban residents to answer the research questionnaires about the urban landscape which was presented by slide projection. The analysis results are as follows: 1) urban residents have highly positive image about the greenery; 2) they highly evaluate urban beautification and amenity function of the greenery; 3) the supply of the greenery is very short regardless of the survey locations; 4) due to the small amount of the greenery, its role in landscape is little. Landscape assessment can be approached from various aspects. Urban residents cognitively regard greenery important, however, in real situation it is not necessarily true. There is a discrepancy of the residents'expectation for the role of the greenery in the reality. Therefore, it is difficult to apply residents'evaluation directly to landscape planning. It is recommended that both planners'judgement and the residents'expectation should be balanced in the planning process.

  • Urban pollution has been a problem in China since ancient times. In modern times, pollution was aggravated by industrialization and urbanization and became closely related to people's lives. Shanghai was the industrial center and the most urbanized place of modern China. As a price, it needed to face extremely serious urban pollution, and the treatment of this problem involved all aspects of social life. Noise pollution let foreigners to interpret the Chinese people and the city of Shanghai from a cultural perspective, and let Chinese residents to understand Shanghai and the nation from a civilized perspective. Pollution regulation made Shanghai the first city in modern China to implement overall pollution control and levy environmental protection fees. It also enabled the Chinese to gradually fight for their rights in urban governance. Urban pollution also brought business opportunities; in the highly commercial city of Shanghai, it promoted the development of some industries. The experience of urban pollution and its treatment prompted the people of Shanghai to rethink and re-recognize modern civilization, and also promoted the formation of Shanghai urban community.

  • The urbanity of high-rise buildings does not simply reference their physical characteristics but also encompasses their impact on the overall urban environment and the daily lives of citizens. This involves the economic benefits, social development, urban culture and public activities that high-rise buildings bring to a city. High-rise buildings are an important aspect of urban development and play a crucial role in providing public services in high-density urban habitats. However, to ensure that their contribution to the city is positive, it is essential to take into account their impact on surrounding buildings and the built environment. This paper analyzes their urban attributes and value system and summarizes their current development status. In short, as the demand for public services continues to evolve, it is necessary for high-rise buildings to keep up with these changes by continuously enhancing their urbanity.

  • Urbanization has led to a reduction in green spaces and thus transformed the spatial pattern of urban land use. An increase in air temperature directly affects forest vegetation, phenology, and biodiversity in urban areas. In this paper, we analyze the changing land use patterns and urban heat distribution (UHD) in Seoul on the basis of a spatial assessment. It is necessary to monitor and assess the functions of green spaces in order to understand the changes in the green space. In addition, we estimated the influence of green space on urban temperature using Landsat 7 Enhanced Thematic Mapper Plus (ETM+) imagery and climatic data. Results of the assessment showed that UHD differences cause differences in temperature variation and the spatial extent of temperature reducing effects due to urban green space. The ratio of urban heat area to green space cooling area increases rapidly with increasing distance from a green space boundary. This shows that urban green space plays an important role for mitigating urban heating in central areas. This study demonstrated the importance of green space by characterizing the spatiotemporal variations in temperature associated with urban green spaces.
