| 2 | Plant drought tolerance trait is the key parameter in improving the modeling of terrestrial transpiration in arid and semi-arid regions显示文摘陆面过程蒸腾作用的模拟制约着天气,气候降水预测的精确度.近几十年来,为了更好地描述植被蒸腾的水力约束,陆面过程模式发展了基于植物性状的植物水力胁迫方案.然而,我们对于植物性状在蒸腾模拟中的地位仍然缺乏了解,植物性状对蒸腾的重要性仍需进一步量化.本研究利用Morris方法评估植物性状参数在通用陆面模式植物水力胁迫方案(CoLM-P_(50)HS)中的重要性,针对17种植物性状,筛选出最为重要的:耐旱性状(P_(50)),气孔性状,和光合作用性状.在12个FLUXNET站点中,参数的重要性由归一化敏感度来衡量.P_(50)的重要性随着降水的减少而增加,而气孔性状和光合作用性状的重要性则随着降水的减少而减少.在干旱或半干旱地区,P_(50)比气孔性状和光合作用性状更重要,这意味着当植物经常经历干旱时,水力安全策略比植物生长策略更关键.而耐旱性状的巨大变异性进一步暗示了多种植物水力安全策略的共存.忽视P_(50)的变异性可能会对陆面过程模式蒸腾作用的模拟造成严重误差.因此,为了更好地表示植物水力功能的变异性,需要增加对耐旱性状的观测并耦合到陆面模式中. | Xintao Liu Xingjie Lu Shulei Zhang Zhongwang Wei Nan Wei Shupeng Zhang Hua Yuan Wei Shangguan Shaofeng Liu Jianfeng Huang Lu Li Xiulan Ye Jinxuan Zhou Wenke Hu Yongjiu Dai | 2022 | Atmospheric and Oceanic Science Letters2022，15，1： | 1 |
