The 2014 IPCC assessment report pointed out that under the influence of climate change and global warming, the probability of extreme events in the future will increase. The nature of Taiwan’s disasters is consistent with global trends. Mainly meteorological disasters.

In addition to Taiwan’s rapid economic development, rapid population growth, increasing urbanization, and increased surface impermeability, surface runoff has been formed. Therefore, urbanization has changed land use and increased extreme weather, making urban areas flooded. Research on water disasters is also important.

There are many related documents on climate change and land use adjustment. It is hoped that, in terms of substantial spatial planning, it is expected that the relationship between urban land use patterns and flooding under different temporal and spatial backgrounds will be explored from the perspective of landscape spatial patterns, and establish The type of land use that most mitigates flooding disasters.
