This paper uses TOPSIS and coupled coordination degree formula to study
the coupled coordination degree between urbanization and geological hazards in 31
provinces of China, and the developing trend of the coupled coordination degree,
with the results showing an improving coordinated development, reaching a
coordinated status from outofcoordinating in most provinces. Coupled
coordination degree level distribution map shows some spatial features that the
coupled coordination degree in the western China is universally higher than in
the central and eastern, and is rising from the western to the centraleastern.
Reasons arise from a conversion in geological hazards prevention and control
concept, establishment of long-term input mechanism and key regional planning.
