研究了快速城市化条件下环杭州湾城市群土壤封闭性和土壤景观格局的动态变化。从1994年到2009年，人口迅速增长，经济发展和定居点蔓延。这种加速的城市化导致了大量的土壤封闭。就整个区域而言，密封土壤的百分比从1994年的2.7%增加到2003年的4.7%，再增加到2009年的8.7%。水稻土，特别是那些质量最好的水稻土，是第一批受害者。在区域范围内，土壤景观变得更加分散和不规则，但随着城市化的加剧，其主导性、多样性和关联性有所下降。空间回归揭示了景观指标与城市化指标和测量期间之间的分歧关系。土壤封闭性和土壤景观格局的变化不仅反映了中国的普遍趋势，而且代表了一个全球性的过程。本研究通过整合遥感、地理信息系统、景观度量和空间回归等技术，为城市化对土壤资源影响的监测提供了一个实用的方法框架。
Dynamics of soil sealing and soil landscape patterns under rapid urbanization were qualified in the Urban Agglomeration around Hangzhou Bay (UAHB), China. Rapid population growth, economic development, and settlement sprawl were identified from 1994 to 2009. Such accelerating urbanization resulted in considerable soil sealing. For the entire region, percentage of sealed soils increased from 2.7% in 1994 to 4.7% in 2003 and to 8.7% in 2009. 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. The dynamics of soil sealing and soil landscape patterns not only reflected common tendencies in China, but represented a global process. Our study provided 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.
