摘　　要：为了厘清岩溶山区人地耦合系统脆弱性特征,在构建岩溶山区人地耦合系统脆弱性评价指标的基础上,运用熵权灰色关联分析法,以贵州省9个地州市为基本评价单元,对其人地耦合系统脆弱性进行定量分析与评价。结果表明:(1)敏感性维度的指标评价等级仅有黔东南州与铜仁地区属于轻度脆弱;暴露度与适应能力维度的指标评价等级仅贵阳市是轻度脆弱,其它地区均是次强度脆弱等级。(2)各地市人地耦合系统脆弱度综合评价结果为六盘水市、毕节地区、安顺市与黔南州属于强度脆弱级;黔东南州、黔西南州、铜仁地区与遵义市属于次强度脆弱级;贵阳市属轻度脆弱级。依据研究结果可将贵州省人地耦合系统划分为强度脆弱区、次强度脆弱区和轻度脆弱区;将各地市人地耦合系统脆弱度与其人地关系特征的对应分析结果表明,人地耦合系统脆弱度的定量分级分析与定性分析具有较好的一致性。In order to clarify the vulnerability characteristics of the coupled human-environment system of karst mountainous, the entropy and grey correlation analysis methods was used to study the 9 prefectures in Guizhou province based on the establishment of vulnerability assessment index of coupled human-environ- ment system in karst mountain areas. And the fragility of the coupled human-natural system was quantita- tively analyzed and evaluated. The results show that： （1） only the southeast states of Guizhou province and the Tongren area belong to the slight fragile of sensitivity dimensions evaluation index grade, only Guiyang city is mild vulnerability grade of the evaluation index of the exposure dimension and the adaptation capability dimension, and the others are strength of the vulnerability grade; （2） the vulnerability comprehensive evalu- ation results of the coupled human-environment system are extreme fragile level of Liupanshui City, Bijie dis- trict, Anshun City and the south states of Guizhou province, the southeast states of Guizhou province, the southwest states of Guizhou Province, Tongren district and Zunyi City belong to the secondary extreme frag- ile level, and Guiyang City is the slightest fragile level. The conclusions are that the coupled human-environ- ment system of Guizhou province can be classified as the extreme fragile area, the secondary extreme fragile area and the mild fragile area based on the results. At last the coupling system vulnerability with the human- environment relationship characteristics of every district of Guizhou Province was analyzed. The results show that the results of qualitative analysis and the quantitative coupled human-environment system of vulnerabili- ty classification have the good correst）ondence.
