Description :
Rapid population growth, economic development, and settlement sprawl were identified from 1994 to 2009 in the Urban Agglomeration around Hangzhou Bay (UAHB), China. Such accelerating urbanization resulted in considerable soil sealing. Paddy soils, especially those of the highest quality, were the first victims. Soil landscapes, at the regional scale, became more fragmented and irregular, but less dominated, diverse and connected as urbanization intensified. Spatial regression uncovered the diverging relationships between landscape metrics with urbanization indicators and measurement period. This study provides a practical methodological framework, by integrating remote sensing, geographical information systems, landscape metrics and spatial regression, for monitoring the impacts of urbanization on soil resources.
