An Analysis of the Evolution of Nanjing’s Green Space Based on Multi-Temporal Remote Sensing Images

Abstract:

This paper extracted green space distribution information from multi-temporal LANDSAT multi-spectral remote sensing images to analyze the evolution of Nanjing’s green space between 1988 and 2007. The findings suggest that the current distribution of green space is not balanced and that the total area of green space has decreased over time. The trend towards fragmentation is obvious in the disproportionately large decline in medium-sized green spaces. Mountain forest and other large green spaces, however, have been better protected. Before 1998, the fragmentation was most apparent in the green spaces of the city’s inner circle. After 1998, the green space in the city’s middle circle began to suffer from the effects of severe human interference. After 2003, the outer circle of green space began to fragment and diminish as a result of urbanization, and the original ecological corridor surrounding the city collapsed.
