| 摘 要： | 为了探讨杉木幼苗叶片功能性状对全球气候变暖的响应与适应机制,在福建三明森林生态系统与全球变化研究站陈大观测点,设置大气增温(开顶箱被动增温,不增温)×土壤增温(电缆增温4℃,不增温)双因子试验,对杉木幼苗叶片生理代谢、形态属性、化学计量学特征等功能性状进行为期1年的研究。结果表明,虽然土壤增温和大气增温对4月和7月的叶片净光合作用速率和水分利用效率没有显著影响,但土壤增温对11月的叶片净光合作用速率有显著促进作用,而大气增温和土壤增温对11月的水分利用效率有显著促进作用。大气增温显著增加比叶面积和叶含水率,并降低叶厚度;而土壤增温则对其均没有显著影响。土壤增温、大气增温均显著增加杉木叶氮浓度,但只有同时大气增温和土壤增温处理才显著提高叶磷浓度。研究结论表明,从叶功能性状角度看,同时大气增温和土壤增温可能更有利于促进杉木幼苗生长。
