This offers a research framework and theoretical reference for the case study in Suzhou area. Then four features of urban land evolution in Suzhou Area are summarized, including amount, locality structure, function structure and spatial structure. It is contended that all these features resulted from the developing process that has been followed with specific institutional transformation of China in this period. And in general economic development and structure shift is the key factor contributing to urban land evolution. Meanwhile rural demographic urbanization and town residents re urbanization and landuse institution reform are other two important underlying causes. In comparison with classical Western model, such urban land evolution happening in Suzhou area is explicitly distinct due to many ‘abnormal’ characteristics. But it is ‘normal’ according to the underlying mechanism, which arguably illustrates the invalidity of empirical theoretical model.展开更多
Based on the study of groundwater isotope(2H and 18O, 34S, 15N, 3H, 14C) in Changzhou, Wuxi and Suzhou area, it is found that the deep confined groundwater has no pollution on the whole, whereas the shallow groundwate...Based on the study of groundwater isotope(2H and 18O, 34S, 15N, 3H, 14C) in Changzhou, Wuxi and Suzhou area, it is found that the deep confined groundwater has no pollution on the whole, whereas the shallow groundwater is polluted to a different degree in the area. The deep confined aquifers (main exploitation aquifers) in Changzhou area and in Wuxi and Suzhou area likely belong to two different aquifers. The main exploitation aquifers in Changzhou area are not connected with those in Wuxi and Suzhou area, or they are connected but not expedited. The lateral run-off of groundwater is at present directed to the exploitation center because of overexploitation of the deep groundwater for a long time, but the flowing speed of groundwater is still extremely slow. The deep confined groundwater is in a close to half close state. The 14C age of groundwater varies from 10000 a BP to 38000 a BP, with the oldest groundwater found at the nearest exploitation center (along the line of three cities of Changzhou, Wuxi and Suzhou) and the youngest at the furthest exploitation center.展开更多

文摘Firstly the general category and pattern of urban land evolution is theorized on the basis of correlating researches. This offers a research framework and theoretical reference for the case study in Suzhou area. Then four features of urban land evolution in Suzhou Area are summarized, including amount, locality structure, function structure and spatial structure. It is contended that all these features resulted from the developing process that has been followed with specific institutional transformation of China in this period. And in general economic development and structure shift is the key factor contributing to urban land evolution. Meanwhile rural demographic urbanization and town residents re urbanization and landuse institution reform are other two important underlying causes. In comparison with classical Western model, such urban land evolution happening in Suzhou area is explicitly distinct due to many ‘abnormal’ characteristics. But it is ‘normal’ according to the underlying mechanism, which arguably illustrates the invalidity of empirical theoretical model.
