Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 1985 to 1999 rapidly developed which showed a difference of mean temperature above +2 0 Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be +4 5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.展开更多

A study of the linkage between three new townsand metropolitan area confirms that substantial commuting trips arestill made. The new towns serve as dormitories for people workingin the metropolitan area. The commuters' reliance on publictransport is significant. The towns are thus far from self-containedeven aller 20 years of development. The public transport network,trip rate, peak factor, purpose, mode choice, costs and journey time,are signilicantly different from those originally estimated. Thesemay be related to distance from the metropolitan area,theavailability of modes, the structure of the public transport netwrk,and changs in the economical structure of Hong Kong. lt suggeststhat the direct and indiscriminant importation of Westernplanning practice to plan new towns with an oriental socio-economicsetting deserves critical review.展开更多

This is the youngest county town in the present-day China. Living in it are 45,000 people displaced by the mammoth Three Gorges Water Project on China’s longest river of the Yangtze. One could see no overhead lines in the town or chimneys on top of the roofs or walls on the four sides. Rainwater and sewage water go down into separate pipelines, with rainwater discharged directly into the Yangtze展开更多

With the urbanization of capital being the theoretical backbone of this paper, we attempt to reveal basic laws inherent in the emergence and proliferation of various forms of urban spaces within a rapidly modernizing country. Considered from various viewpoints such as land institutions, national policy designs, and the fi nancial capital and bank system, our paper covers: a historical overview of China's post-reform new towns, a theoretical framework to explain related phenomena, empirical approaches to interpreting the contributory factors, and a theoretical outline for further research.展开更多

Firstly, the paper defines employment-intensive areas and gets the average employment density of each new town according to the employment density data. Then it marks out the scope of the employment influence through analyzing the sources of workers in each new town in accordance with the commuting data. Finally, it analyzes the jobs-housing balance of each new town using independence index, finding that suburban new towns in Shanghai have become main clusters of economic activities, while the scope of employment influence in each new town is still concentrated in its administrative area, with less attraction to residents in other areas. The independence index demonstrates a law that the suburban new town which is farther from the central city sees a higher degree of jobs-housing balance. Among them, new towns located in the outer suburbs with a low independence index indicate their special development situation, the reason of which is worth further study.展开更多
