The frequency and severity of drought events may increase in the future due to climate change. We have developed three meteorological drought scenarios for Austria in the period 2008-2040. The scenarios are defined based on a dry day index which is combined with bootstrapping from an observed daily weather dataset of the period 1975-2007. The severity of long-term drought scenarios is characterized by lower annual and seasonal precipitation amounts as well as more significant temperature increases compared to the observations. The long-term impacts of the drought scenarios on Austrian crop production have been analyzed with the biophysical process model EPIC (Environmental Policy Integrated Climate). Our simulation outputs show that—for areas with historical mean annual precipitation sums below 850 mm— already slight increases in dryness result in significantly lower crop yields i.e. depending on the drought severity, between 0.6% and 0.9% decreases in mean annual dry matter crop yields per 1.0% decrease in mean annual precipitation sums. The EPIC results of more severe droughts show that spring and summer precipitation may become a limiting factor in crop production even in regions with historical abundant precipitation.展开更多
目的分析基于IMPACT模式的护理管理结合低升糖指数膳食管理对2型糖尿病(T2DM)患者饮食行为及自护能力的影响。方法选取2021年1月至12月收治的100例T2DM患者为研究对象,按照随机数字表法将其分为对照组与观察组,各50例。对照组采用常规...目的分析基于IMPACT模式的护理管理结合低升糖指数膳食管理对2型糖尿病(T2DM)患者饮食行为及自护能力的影响。方法选取2021年1月至12月收治的100例T2DM患者为研究对象,按照随机数字表法将其分为对照组与观察组,各50例。对照组采用常规护理干预,观察组在对照组基础上加基于IMPACT模式的护理管理结合低升糖指数膳食管理。比较两组的饮食行为、自护能力以及血糖控制水平。结果干预后,观察组的饮食行为量表各维度评分高于对照组,差异具有统计学意义(P<0.05)。干预后,观察组的自我护理能力测定量表(ESCA)各维度评分高于对照组,差异具有统计学意义(P<0.05)。干预后,观察组的空腹血糖(FBG)、餐后2 h血糖(2 h PBG)水平低于对照组,差异具有统计学意义(P<0.05)。结论基于IMPACT模式的护理管理结合低升糖指数膳食管理不仅能够改变患者饮食行为,还能加强其自护能力,以此提高血糖控制水平,值得推广。展开更多
