[Impact of urbanization on pedodiversity in Suzhou area].
Based on the TM remote sensing information of 1984, 1995, 2000 and 2003, this paper quantitatively analyzed the spatial-temporal dynamic changes of pedodiversity in Suzhou area under quickly growing urbanization. The results showed that in this area, clay loamy typic-hapli-stagnic anthrosol and fine sand clay loamy typic-hapli-stagnic anthrosol were the predominant soil types, but their distribution area decreased 5.11% and 3.14%, respectively, in latest 20 years. Jinchang, Pingjiang and Canglang Districts were the focuses of urbanization in Suzhou area, where pedodiversity changed furiously. During 1984 approximately 2003, more than 90% of the clay loamy typic-hapli-stagni gleyosol in Pingjiang District and sandy calcaric-mottlic-udi-orthic primosol in Taicang City were almost disappeared, and changed into residential area. Statistical analysis showed that urbanization had a significant impact on pedodiversity, and was the prime driving force on the pedodiversity in Suzhou area.
