摘要: 研究表明,全球增温可导致干旱趋势的发展,为了解东北主要森林分布区长白山广大低海拔地区阔叶红松林主要组成树种对干旱趋势的反应,通过PV曲线技术测定不同树种的水分参数值,比较评价其耐旱能力,得到长白山阔叶红松林主要树种耐旱性从高到低依次为:山杨、蒙古柞、樟子松、红松、长白松、黑桦、春榆、色木、糠椴、紫椴、红皮云杉、白桦、臭松、水曲柳、核桃楸、黄菠萝.

Abstract: Global warming may result in the development of drought. To understand the response of maintree species in broadleaf-Korean pine forest at low elevation on Changbai Mountain to the predieted drought, water-related parameters were determined by PVcurve technique to evaluatethe drought-tolerance of these tree species. The species be able to tolerate drouht were put indecreasing order as following: Populus darvidiana, Quercus mongolica, Pinus sylvestris var.mongolica, Pinus koraiensis, Pinus sylvestrisformis, Betula dahurca, Ulmus Propinque,Acer mono, Tilia mandshurica, Tilia amurenses, Picec koraienses, Betula platyphylla, Abier mephrolepis, Fraxinus mandshurica, Juglans,mandshurica, Phellodendron amuremse.

Key words: Global warming, PV curve technique, Drought-tolerance, oxidation resistance, Kobresia pygmaea, K. tibetica, warming, morphology
