Abstract:: 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-environment system in karst mountain areas. And the fragility of the coupled human-natural system was quantitatively 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 evaluation results of the coupled human-environment system are extreme fragile level of Liupanshui City, Bijie district, 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 fragile level, and Guiyang City is the slightest fragile level. The conclusions are that the coupled human-environment 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 vulnerability classification have the good correspondence.
