摘要

近几十年来,许多地区的树木生长量下降,这与气候变暖导致缺水加剧有关。这种现象在气温较高的低纬度地区可能更为明显。然而,人们对气温升高改变树木生长表现的过程还不甚了解。在本研究中,我们结合树环数据(包括 340 个增量核心)和遥感植被指数数据,研究了蒙古松(Pinus sylvestris var.(蒙古松是中国北方植树造林的重要树种,我们研究了其在引种地区(低纬度)和原产地(高纬度)的生长表现对环境因素的影响。)在引种地区,树环宽度指数(RWI)和胸径基部面积增量的下降更为显著,与卫星植被指数的较低值和较大变化相吻合。在引种区的大多数月份里,RWI 与气温呈较强的负相关,而与自校准帕尔默干旱严重程度指数呈正相关。这些结果表明,低纬度地区温度升高导致的干旱胁迫增强可能是蒙古松人工林生长衰退的关键因素。气温升高会加剧低纬度缺水地区的干旱胁迫,从而对树木生长产生负面影响,这突出表明在气候变暖导致干旱化的情况下,这些地区的森林管理需要减少水胁迫。

Increased temperatures contribute to early aging of plantation-grown Mongolian pine in introduced areas at lower latitudes

A decline in tree growth has occurred in numerous regions over recent decades and is associated with enhanced water deficits driven by climate warming. This phenomenon may be more noticeable at lower latitudes with higher temperatures. However, the process by which these elevated temperatures alter growth performance is not well understood. In this study, by combining tree-ring data (including 340 increment cores) and remotely sensed vegetation index data, we investigated the long-term growth performance of Pinus sylvestris var. mongolica Litv. (Mongolian pine), an important species for afforestation in northern China, in response to environmental factors in an area of introduction (lower latitude) and its native range (higher latitude). More notable decreases in both tree-ring width index (RWI) and basal area increment at breast height coincided with lower values and larger variations in the satellite-derived vegetation index in the area of introduction. The RWI showed stronger negative correlations with temperature and positive correlations with the self-calibrating Palmer drought severity index during most months in the introduction area. These results indicate that enhanced drought stress caused by elevated temperatures in lower latitudes might be a key factor for the growth decline in Mongolian pine plantations. The negative impact of increased temperatures on tree growth through exacerbating drought stress at lower latitudes with water deficit highlights the need to reduce water stress in forest management in such areas under climate warming-driven aridification.

期刊介绍: The Journal of Forestry Research (JFR), founded in 1990, is a peer-reviewed quarterly journal in English. JFR has rapidly emerged as an international journal published by Northeast Forestry University and Ecological Society of China in collaboration with Springer Verlag. The journal publishes scientific articles related to forestry for a broad range of international scientists, forest managers and practitioners.The scope of the journal covers the following five thematic categories and 20 subjects: Basic Science of Forestry, Forest biometrics, Forest soils, Forest hydrology, Tree physiology, Forest biomass, carbon, and bioenergy, Forest biotechnology and molecular biology, Forest Ecology, Forest ecology, Forest ecological services, Restoration ecology, Forest adaptation to climate change, Wildlife ecology and management, Silviculture and Forest Management, Forest genetics and tree breeding, Silviculture, Forest RS, GIS, and modeling, Forest management, Forest Protection, Forest entomology and pathology, Forest fire, Forest resources conservation, Forest health monitoring and assessment, Wood Science and Technology, Wood Science and Technology.
