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

When a town government department is developing its economy, it must also do a good job in the development of human resources in the town. Only by effectively using the government's functional guidance, providing superior living and working conditions for talents and attracting talents can it promote the healthy development of human resources development in a town. According to the characteristics of a town's economic development and the demand for talents, a town's talent strategic development system is established. Meanwhile, the talent policy is gradually opened up, talents are increased to start businesses and obtain employment in the region, talents' advantages are brought into play, the effectiveness of talent development is enhanced, and the talent environment of a town is trained, which can enhance the power of human resources development in a town.展开更多

文摘Talent is the key resource for the whole social and economic development, and the economic development of a town cannot be separated from more professional talents. When a town government department is developing its economy, it must also do a good job in the development of human resources in the town. Only by effectively using the government's functional guidance, providing superior living and working conditions for talents and attracting talents can it promote the healthy development of human resources development in a town. According to the characteristics of a town's economic development and the demand for talents, a town's talent strategic development system is established. Meanwhile, the talent policy is gradually opened up, talents are increased to start businesses and obtain employment in the region, talents' advantages are brought into play, the effectiveness of talent development is enhanced, and the talent environment of a town is trained, which can enhance the power of human resources development in a town.
