Abstract:

To adapt to climate change becomes important issue both for the international negotiation and domestic practical adaptation. Clarified relevant terms related with adaptation have positive roles for related scientific research and adaptive actions. The paper identify adaptation is a definition of behavior or measures, no necessarily need for quantitative results; adaptive capacity has clear evaluation index system, and eventually produce quantitative assessment results; Adaptability focus on ability property, its basic conclusion is with or without, strong or weak. The adaptability backed by the quantitative conclusion or determined specific strength is equivalent to adaptive capacity. For the vulnerability assessment, exposure reflects the basic situation of the main object associated with climate change, sensitivity shows the effects of climate change on the subject object, adaptive capacity is the combination of economic capital, natural resources, technical ability and social security, all the four elements involve specific indicators that need take into consideration and selection according to the subject property. Disaster risk management and adaptation to climate change have several differences within the main category, driving factors, the purpose of the action, but both focus on improving the resilience on climate change/climate disasters and enhancing the ability to prevent, bear and restore from adverse effects.

Key words: adaptation, sensitivity, vulnerability, resilience, risk management
