摘要: 选取经济、农业、社会和资源环境系统作为区域气候变化适应度的评价子系统,运用AHP分析法,确定各评价因子的权重,运用模糊综合评判分析法,确定对气候变化适应的隶属度并判断适应度。结果表明,咸阳市1998-2007 年对气候变化适应的隶属度呈逐年增加趋势,适应度处于由“较弱”向“一般”过渡状态,区域整体及各子系统对气候变化的适应处于低水平状态。其中经济系统适应度由“弱”到“强”,受不利因素影响程度小;农业系统适应度由“弱”到“一般”,受不利因素影响程度较大;社会系统适应度由“较弱”到“较强”;资源环境系统适应度由“弱”到“一般”,受不利因素的影响程度较大,稳定性差。

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.
