【摘要】：從自然因素、社會(huì)因素、生態(tài)因素等3個(gè)層面選取12個(gè)指標(biāo),構(gòu)建基于模糊灰色系統(tǒng)理論評(píng)價(jià)模型,對(duì)貴州省農(nóng)業(yè)旱災(zāi)脆弱性進(jìn)行初步探討。結(jié)果表明:貴州省生態(tài)環(huán)境脆弱,易誘發(fā)旱災(zāi)且恢復(fù)力差,9個(gè)脆弱性分區(qū)中,有6個(gè)嚴(yán)重分區(qū),3個(gè)中度分區(qū);用4個(gè)典型指標(biāo)與綜合評(píng)價(jià)結(jié)果進(jìn)行灰色關(guān)聯(lián)度分析,得出喀斯特地區(qū)農(nóng)業(yè)旱災(zāi)脆弱性與這4種因素都有關(guān)聯(lián)性,其關(guān)聯(lián)程度大小順序?yàn)?地表水資源量GDP人口喀斯特面積�？λ固胤植济娣e對(duì)貴州省農(nóng)業(yè)旱災(zāi)脆弱性具有一定程度的影響,但是,經(jīng)濟(jì)的發(fā)展、科技的進(jìn)步以及人文因素的作用,正逐漸弱化著喀斯特對(duì)農(nóng)業(yè)旱災(zāi)脆弱性的影響力。
[Abstract]:12 indexes were selected from natural factors, social factors and ecological factors, and based on fuzzy grey system theory evaluation model, the vulnerability of agricultural drought in Guizhou Province was preliminarily discussed. The results showed that the ecological environment of Guizhou Province was fragile. The drought is easy to induce and the resilience is poor. Among the 9 vulnerability zones, there are 6 severe and 3 moderate, and 4 typical indexes are used to analyze the grey correlation degree with the results of comprehensive evaluation. It is concluded that the vulnerability of agricultural drought in karst area is related to these four factors. The order of correlation degree is: surface water resource GDP population karst area. Karst distribution area has a certain degree of influence on agricultural drought vulnerability in Guizhou Province. However, economic development, Advances in science and technology and the role of human factors are weakening the impact of karst on agricultural drought vulnerability.
