落叶松属常分布于高纬高海拔地区,年际生长节律明显,在全球气候变化重建研究中具有重要的地位。本文对欧洲、北美、亚洲地区主要的落叶松属树种近年来取得的成果进行了综合分析,以地区为单位,梳理研究思路,概述研究重点及特色。全球落叶松属研究以对气温敏感性较高的轮宽为主,约占72%;其次是最大晚材密度,约占16%。其中,尤以欧洲落叶松和西伯利亚落叶松研究成果最多。在各地区中,欧洲的研究成果约占61%,倾向于大空间尺度多树种综合研究。北美研究常结合特殊的地形条件及生态事件进行,落叶松叶蜂虫害信息的提取是研究的重点。亚洲地区以西伯利亚落叶松为主,在20世纪90年代就已出现大量的重建成果。中国落叶松属有10种1变种,但研究相对落后于其他地区,近年来才在一些树种上取得突破,并出现了树轮密度的研究成果,未来应重点转向空间“场”的研究和多树种综合研究。
Larix is often distributed in the high latitudes and high altitudes, and has an obvious rhythm of interannual growth and plays an important role in the study of global climate change reconstruction. In this paper, a comprehensive analysis of the achievements made by the major larch species in Europe, North America and Asia in recent years is made. Taking the region as a unit, the research ideas are summarized and the research focuses and characteristics are outlined. Global larch research is mainly concerned with temperature-sensitive wheel width, accounting for about 72%; followed by the largest latewood density, accounting for about 16%. Among them, Larix Europeana and Larix sibirica have the most research results. In all regions, research results in Europe accounted for about 61%, tend to large-scale multi-species integrated research. North American research often combined with special topographical conditions and ecological events, extraction of information on larch leaf bee pests is the focus of research. In Asia, mainly Siberian larch, a large number of reconstruction achievements have been made in the 1990s. There are 10 species and 1 species of larch in China, but the research lags behind other regions. In recent years, some breakthroughs have been made in some tree species and the results of research on tree-ring density have appeared. In the future, the research should focus on the study of space And multi-tree comprehensive study.
