| Zusammenfassung |
| Due to the convenient transportation and construction, cities are prone to
be situated in areas with flat terrain and unstable sediments, resulting in
the concurrence of ground subsidence and urbanization. Here the interaction
between geology, anthropogenic processes and ground subsidence geo-hazards
were investigated in the Greater Pearl River Delta region of China.
Geological evidences and 2006–2010 persistent scatterer data indicate that
anthropogenic activities are dominant, although the distribution of river
system and Quaternary sediments are also highly related to significant
displacements (primarily at a rate of −15 to 15 mm a−1). The surface
displacements derived by synthetic aperture radar interferometry suggest
that the urbanization rhythm has to be routinely monitored. Considering
analogous urbanization modes, particularly in developing countries, ground
subsidence monitoring together with the analysis of its driving force are
critical for geo-hazards early-warning, city planning as well as
sustainable urbanization. |
