摘要
农户既是承灾体也是防灾抗灾的主体,因此农户在面对灾害时的风险承受能力对减轻低温冻害造成的农业损失具有重要意义。以云南高原部分农户为研究对象,选取巍山县、陆良县、彝良县为研究区域,构建了农户低温冻害风险承受能力评价指标体系,并采用层次分析法和灰色综合评价法结合对风险承受能力进行综合评价。结果显示,研究区域农户风险承受能力综合评价值为3.21,属于中等水平,农户风险承受能力还有待提高;影响因素的综合评价值为心里稳定性>灾损预期>复苏力;三个样本区域复苏力大小表现为陆良县>巍山县>彝良县。
Farmers are both disaster - bearing bodies and the main body of disaster prevention and resilience. Therefore, the risk bearing capacity of rural households in the face of disasters is of great significance in reducing the agricultural losses caused by low temperature and freezing damage. The paper takes some farmers in Yunnan Plateau as the research object, and selects Weishan County, Luliang County and Yiliang County as the research area, and constructs an evaluation index system for farmers＇ risk tolerance of low temperature freezing damage, and combines the analytic hierarchy process with the gray comprehensive evaluation meth- od. Comprehensive assessment of risk tolerance. The results show that the comprehensive evaluation value of farmers＇ risk tolerance in the study area is 3.21, which is a medium level, and the risk tolerance of farmers needs to be improved; The comprehensive assessment of the influencing factors was the cardiac stability 〉 the expected loss of the disaster 〉 the resuscitation force; the resuscitation force of the three sample regions was represented by Luliang County 〉 Wishan County 〉 Yiliang County.
