Abstract: The economic system, agricultural system, social system and the resources and environment system are selected as the subsystems for the evaluation of adaptation to regional climate change. The determinative weight values of evaluation factors are confirmed by using the AHP analytical method. The membership degree of climate change adaptation and the adaptation values are calculated by the method of fuzzy comprehensive evaluation. The result is that the membership degree of climate change adaptation shows an increasing trend year by year in Xianyang City from 1998 to 2007. The level of overall and partial adaptation is low, and it is in the transition state from "weak" to "general". The adaptation of economic system which is seldom affected by negative factors is in a state from "weak" to "strong". The adaptation of agricultural system which is affected greatly by negative factors is in a state from "weak" to "general". The adaptation of social system which develops stably and rapidly is in a state from "weak" to "strong". The adaptation of resources and environment system is in a state from "weak" to "general", which has a poor stability and is affected greatly by negative factors.
