生计资本对玉米高温脆弱性的影响研究

Study on the Impact of Livelihood Capital on the High Temperature Vulnerability of Maize

文章以陕西、宁夏和山东三省的玉米种植户为研究对象,评估农户生计资本对玉米高温脆弱性的影响;选择曝光和敏感性衡量脆弱性指数,自然、金融、人力、社会和物质资本衡量适应能力;逐步回归分析表明16个生计指标中仅全年气温最大值、自己耕种的面积和农业收入对玉米高温的脆弱性有显著影响,由此可知,生计资本对玉米高温脆弱性的影响具有局限性。

The article uses Shaanxi,Ningxia,and Shandong farmers as the study objects to evaluate the impact of farmers’livelihood capital on the high temperature vulnerability of maize select exposure and sensitivity to calculate the vulnerability index,and the natural,financial,human,social and physical capital to measure adaptability,stepwise regression analysis shows that among the 16 livelihood indicators,only the maximum annual temperature,self-cultivation area and agricultural income have a significant impact on the vulnerability of maize to high temperature.Therefore,it can be seen that the impact of livelihood capital on the high temperature vulnerability has limitations.
