Abstract
Many mega-cities in China have experienced the rapid urbanization which caused various environmental problems in association with the reduction of green spaces. This study aims at quantifying the spatio-temporal dynamics of urban green spaces in response to the rapid urbanization and greening policies in Shanghai, China. The results of analysis showed that the spatio-temporal distribution of green spaces at the landscape level was not uniform inside the outer-ring roads of Shanghai, and green space dynamics between 2000 and 2010 could be characterized by the unique values of landscape metrics according to the locations, Pudong and Puxi of the city. The gradient analysis undertaken along the east-west direction from the city center also demonstrated that the landscape metrics for each type of green spaces were characterized by the different process of urbanization and the implementation of the greening policy in Pudong and Puxi of Shanghai city.
