干旱灾害是影响面最广的一种天气灾害,而农户对干旱的脆弱性影响灾害的受损程度,与农村贫困密切相关。文章应用灰色系统理论分析计算了干旱脆弱性各影响因子与我国农村贫困的关联度。结果表明:农业干旱脆弱性影响因子中农业GDP所占比例对农村贫困影响最大,单位面积粮食总产量的影响次之,其他依次为农业就业人口所占比例、农村恩格尔系数、农民人年均工资性收入占纯收入比例、耕地灌溉率及财政支农支出。这一结论对增强抗灾能力,减轻农村贫困具有重要的指导意义。
Drought disaster is the most affected one of the weather disasters, and the vulnerability of farmers to drought affect the degree of disaster damage, and rural poverty are closely related. In this paper, the gray system theory is used to analyze the relationship between the various factors of drought vulnerability and rural poverty in China. The results show that the proportion of agricultural GDP in agricultural drought vulnerability factors has the greatest impact on rural poverty, followed by the total output of grain per unit area, followed by the proportion of agricultural employment, the rural Engel coefficient, average annual salary of peasants The proportion of sexual income in net income, the rate of irrigated farmland and the expenditure of financial support for agriculture. This conclusion is of great guiding significance for enhancing disaster resilience and alleviating rural poverty.
