This study used GIS technology, remote sensing images of 1949, 1966, 1981, 1984, 1988, 1992, 1996 and 2000, to analyze the spatial process of urbanization and its impact on the soil resources in Yixing city, southeast China. The results showed
that the urban area grew more than three-fold during 51 years and the loss of paddy soil accounted for 82,9% of all soil loss. According to the expansion dynamics and the results of spatial metrics, the urban expansion process in Yixing could be divided into 4
steps. The study also indicated that the urban expansion was encouraged by the transportation system, however, restricted by the rivers, lakes and hills.
Impacts of urbanization on topsoil nutrient balances - a case study at a provincial scale from Fujian, China

In Fujian province, the change in crop spectrum and land use by urbanization has resulted in 2 extreme trends in topsoil : nutrient depletion in grain-dominated regions and nutrient overloads in city suburbs. The rapid changes in land use and crop
spectrum caused by urbanization therefore created a challenge to the traditional soil nutrient management derived mainly from paddy fields and an urgent need for new management schemes in the province. The study provides valuable insights into nutrient
management and soil sustainability in the context of rapid urbanization and population growth in Fujian.
Establishing a spatial grouping base for surface soil properties along urban-rural gradient. A case study in Nanjing, China

The aim of this study was to determine the most sensitive grouping system in depicting and explaining variations of soil attributes around an urban area, in Nanjing. Grouping methods, including urban-rural division, in situ vegetation type, land use
types in different scales and numerical clustering, were compared for both single soil attributes and soil set defined by multiple variables. The result shows urbanization has a strong impact on many soil properties, especially that of gravel content

This paper applied remote sensing method in the study of urban forest in Jinan City. Results show that there are various kinds of greenbelts in Jinan City, including public greenbelt, residential greenbelt, greenbelt attached to branches, protective
greenbelt in production, landscape forest and road greenbelt. Using the remote sensing investigation, the AA. divided the suburban forest into 7 classes. Suggestions to improve urban forest in Jinan City are given : increasing the number of greenbelt
Historical change of soil Pb content and Pb isotope signatures of the cultural layers in urban Nanjing
Influences of rapid urbanization and industrialization on soil resource and its quality in China
The vertical change of soil properties denotes the historical change of human activities, and therefore, urban soil can be considered as a record of history of urban development. This study aimed to reconstruct the historical change of Pb content

In this study, Buji River basin in Shenzhen Region was selected to analyse the effect of land use and cover change on surface runoff. Teledetection data are used. The impact of urbanization is discussed.
Surface water quality of factory-based and vegetable-based peri-urban areas in the Yangtze River Delta region, China
Influences of rapid urbanization and industrialization on soil resource and its quality in China
Detailed surveys of surface water in 2 contrasting peri-urban areas in the Yangtze River Delta region of China were conducted to determine the distribution of heavy metals, nitrogen (N) and phosphorus (P) as well as the speciation of N and P
