快速城市化背景下上海绿色空间时空动态演变
The spatio-temporal dynamics of the green space and landscape in rapidly urbanizing Shanghai
摘要
Abstract
Rapid urbanization has caused a series of eco-environmental problems associated with the change of green space.A common consensus has been achieved that green spaces are valuable resources in coupled natural and human urban systems.As the most rapidly urbanizing area in China,Shanghai's landscape patterns experienced a tremendous change.Through the integrated approach of remote sensing and geographic information system (GIS) techniques,four Landsat TM/ETM+ imagery acquired from 1997 to 2008 were used to quantitatively characterize the patterns of urban green space change in the fast-growing Shanghai Metropolis.Results showed that the cropland decreased 661.50 km2 with a drop of 22.69％.The area of forest,shrub and water were kept in balance whereas the spatial dynamics changed dramatically in the study area.As a result,during 1997 and 2008,approximately 72.14％ of the cropland was converted to urban/construction land and 37.37％ to urban green space.The spatial distributions of the landscape diversity identified the areas where the landscape diversity significantly changed in the metropolitan area of Shanghai.The spatiotemporal pattern of the landscape diversity in the suburban area was higher than the central area of Shanhai.关键词
