Natural Disasters, Population Distribution and Housing Price in Taiwan: A Spatial Analysis

In recent years, climate change has caused severe impacts on various countries and exacerbated the impact of natural disasters on human settlements. Due to Taiwan's high risk of multiple natural disasters and complex terrain changes, the impact and damage of disasters it faces are more severe than most countries. This makes Taiwan a suitable research site to observe and discuss the impact of natural disasters on human settlements. Research on natural disaster risk has long focused on the impact of a single disaster. However, the impact of disasters is often multiple and related to the vulnerability of the regional environment. In this case, the assessment of terrain is critical. On the premise of natural disaster prevention, the livable environment and areas not suitable for development should be defined first. Through the integration of topography and natural disasters, this study uses a geographic information system to explore the relationship between Taiwan's livable environment, unsuitable development areas, and the current population distribution and agglomeration; By contrasting the spatial distribution of disasters such as landslides, flooding, and land subsidence, we explore how the diversity of natural disasters directly affects the living environment and indirectly causes fluctuations in housing prices.
