中国Tengger沙漠的灌木由于水和碳的使用减少,而不是能源的缺乏,其生长速度越来越快。 Shrubs in China’s Tengger Desert are growing less due to reduced water and carbon use, not energy lack, as they grow larger.

中国Tengger沙漠边缘干地灌木生长下降的原因是水运量减少和碳同化, 而不是随着植物规模的扩大而耗竭能源储备。 A new study published in New Phytologist reveals that declining growth in dryland shrubs at China’s Tengger Desert edge is driven by reduced water transport and carbon assimilation, not depleted energy reserves, as plant size increases. 中国和美国研究机构的研究人员发现两种灌木物种在辐射增长和液压效率方面都出现了类似的下降,尽管对口调节和稳定的非结构碳水化合物水平有所不同。 Researchers from China and U.S. institutions found both shrub species showed similar declines in radial growth and hydraulic efficiency, despite differing stomatal regulation and stable nonstructural carbohydrate levels. 研究结果强调,植物规模是气候变化下灌木抗御能力的一个关键因素,并支持改进防治荒漠化的恢复战略。 The findings highlight plant size as a key factor in shrub resilience under climate change and support improved restoration strategies for combating desertification.
