The impact of urban planning on land use and land cover in Pudong of Shanghai, China
Functional zones in cities constitute the most conshttps://p.9136.com/1wponents of newly developed urban areas, and have been a hot spot fordomestic and foreign investors in China, which not only show the expanse of urban space accompanied by the shifts both in landscape (fromrural to urban) and land use(from less extensive to extensive), but also display the transformation of regional ecological functions.By using thetheories and methods of landscape ecology, the structure of landscapes and landscape ecological planning can be analyzed and evaluated forstudying the urban functional zones' layout.In 1990, the Central Government of China declared to develop and open up Pudong New Area so as to promote economic development in Shanghai.Benefited from the advantages of Shanghai' s location and economy, the government of PudongNew Area has successively built up 7 different functional zones over the past decade according to their functions and strategic goals.Based onthe multi-spectral satellite imageries taken in 1990, 1997 and 2000, a landscape ecology analysis was carried out for Pudong New Area ofShanghai, supported by GIS technology.Green space (including croplands) and built-up areas are the major factors considered in developingurban landscape.This paper was mainly concerned with the different spatial patterns and dynamics of green space, built-up areas and newbuildings in different functional zones, as influenced by different functional layouts and development strategies.The rapid urbanization inPudoag New Area resulted in a more homogeneous landscape.Agricultural landscape and suburban landscape were gradually replaced by urbanlandscape as the degree of urbanization increased.As a consequence of urbanization in Pudong, not only built-up patches, but also newly-builtpatches and green patches merged into one large patch, which should be attributed to the construction policy of extensive green space as theurban development process in Pudong New Area.The shape of green area of 7 functional zones became more and more regular because of thehorticultural needs in Shanghai urban planning.Some suggestions were finally made for the study of future urban planning and layout.
