Impact of urbanization on pedodiversity in Suzhou area

Abstract

Abstract: 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 1984～2003,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.

Key words: Suzhou area, Urbanization, Pedodiversity, Spatial-temporal characteristics
