Abstract
Studying flood and waterlogging disaster risk induced by land use change would have
implicational significance to urban planning and sustainability. Like other Karst
landscape region, Jinan city has been also suffering from the threat of flood and
waterlogging disaster, which is located in the Karst region of North China. In this
study, we analyze the spatial and temporal land use change in Jinan city during
2000—2020 based on RS, GIS and field investigation. Further, using the SCS-CN model
and GIS, we simulate flood and waterlogging disaster based on land use change. This
study extends beyond merely furnishing scientific data support for local governmental
efforts in disaster prevention and mitigation to urban flood and waterlogging.
Human encroachment on Karst mountainous areas makes these urban communities more
vulnerable to flood and waterlogging hazards. Also, the urban and Karst ecosystems
are fragile ecosystems, whose integration and overlap will bring about the double
vulnerability for the urban ecosystem. All these could raise higher management requirements
for the sustainable development of Karst urban mountainous regions in North China.
In future, strengthening more protection in Karst mountainous regions of North China
will become the top concern of various local governments.
