Severe trauma is one of the main causes of premature death,posing a significant challenge to public health systems.[1]At present,there is a lack of universally accepted guidelines for rapid detection of life-threatening severe trauma,[2]and the accuracy of existing prognostic models in predicting early death is limited.[3,4]Severe non-brain-injured trauma(SNT)patients account for approximately 70%of all trauma-related ***,there is a lack of studies on early death in SNT patients.[5]This study aims to identify risk factors associated with early death(≤72 h post-admission)in SNT patients.

土地利用/覆被变化会增加区域碳储量或引发碳损耗,进而影响全球气候.研究湾区土地利用与碳储量变化的影响机制,对区域生态系统保护及社会经济可持续发展具有重要意义.基于InVEST模型和PLUS模型,分析了粤港澳大湾区土地利用与碳储量的动态变化特征及影响机制,进一步模拟预测了2030年3种发展情景(自然趋势情景、建设用地优先情景和生态优先情景)下土地利用类型变化对碳储量的影响.结果表明:(1)2000~2020年粤港澳大湾区的耕地(减少5.38%)和建设用地(增加8.68%)变化最显著,其余用地类型的变化较小.林地作为大湾区的主要用地类型,同样也是重要的碳库,空间上集中分布于东、北、西三面的台地和丘陵地区,碳储存低值区集中于中部平原,以建设用地为主.(2)受不同用地类型相互转化的影响,粤港澳大湾区的碳损失了20.12×10^(6) Mg.耕地和林地面积的减少以及建设用地面积的增加是碳损耗的主要原因.(3)模拟研究发现生态保护措施将有效提高区域碳储量.具体来说,当耕地、林地和草地向建设用地的转化减少20%,湿地和水体向建设用地的转化减少30%时(生态优先情景),区域碳储量可增加2.58×10^(6) Mg.研究结果可以为土地利用和城市发展规划的制定提供理论依据,促进粤港澳大湾区“碳达峰碳中和”目标的实现.
