Climate change vulnerability assessment system and method

摘要

PURPOSE: A climate change vulnerability evaluation system and a method for the same are provided to support local governments to set segmented items of climate change adaptation policies. CONSTITUTION: A climate change vulnerability evaluation method includes the following steps: climate change variables are segmented and saved; sensitivity variables, which represent the influence of the climate change variables, are segmented and saved; adaptation capability variables for reducing the influence of the climate change variables and sensitivity variables are segmented and saved; boundary data for administrative districts is saved; respective climate change variables, sensitivity variables, and adaptation capability variables for respective administrative districts are obtained; proxy variables for the respective climate change variables, sensitivity variables, and adaptation capability are saved; weighted values for the respective climate change variables, sensitivity variables, and adaptation capability and for the proxy variables are saved; the proxy variable is standardized; vulnerability is obtained using the standardized proxy value and the weighted values; the vulnerability is standardized; vulnerabilities are compared by administrative district; and the variables, vulnerabilities, and information of the administrative districts are displayed.
