摘要

利用从印度东北部曼尼普尔收集的36棵树芯,建立了39年(1980-2018年)长的卡西松年轮宽度年表。根据树木年轮年代学统计,从该地区获得了这棵树的显著树木年代学潜力。在格网气候记录(平均温度和降雨量)和环宽年代学之间建立了线性响应关系。3月24日~ 5月27日日平均气温与树木生长呈显著负相关,2月24日~ 3月25日降雨量与树木生长呈显著正相关。这项研究是印度首次尝试分析树木年轮生长对日常气候记录的响应。建议在该地区进一步开展更多样本的研究,以加强年代学统计,扩大年代学时间跨度。

Response between tree-rings of Pinus kesiya and daily climate data – A study from Manipur, Northeast India
A 39 years (1980–2018 C.E.) long tree–ring width chronology of Khasi Pine (Pinus kesiya) was developed using 36 tree cores collected from Manipur, Northeast India. The significant dendrochronological potential of this tree was achieved from this region, based on tree–ring chronology statistics. A linear response between ring–width chronology of P. kesiya and daily gridded climate (mean temperature and rainfall) records has been established. A significant negative association has been observed between daily mean temperature and tree growth during March 24 to May 27, whereas, rainfall showed positive response from February 24 to March 25. This study is a maiden attempt from India to analyze the response of tree ring growth to the daily climatic records. Further studies with a larger number of samples of P. kesiya are recommended from this region to strengthen the chronology statistics and to extend the chronology time span.
