摘  要：
利用云南三江并流区域的4个针叶树树轮年表和1982—2005年GIMMS(Global Inventory Modelling and Mapping Studies)3g NDVI数据,分析了该区树轮宽度指数、NDVI及气候因子的相关关系。结果表明:区域NDVI年际变化与年际降水具有较好正相关关系,且都处于波动上升趋势;树轮宽度指数与夏季温度显著正相关,而NDVI则与上一年及当年7月降水显著正相关,反映出树干生长与冠层生长受控因子的不同;树轮宽度指数仅与7月NDVI具有正相关关系,针叶树反映部分NDVI变化,三江并流地区NDVI影响因子复杂多样。

摘  要：
Based on four coniferous tree ring chronologies and GIMMS(global inventory modelling and mapping studies)3 g NDVI data from 1982 to 2005 in the three parallel rivers region of Yunnan province,the correlation among tree ring width index,NDVI and climatic factors was analyzed in this paper.The results show that the interannual variation of NDVI is positively correlated with interannual precipitation,and all of them are in a fluctuating upward trend.Tree ring width index is positively correlated with summer temperature,while NDVI is positively correlated with precipitation of July in the previous and currant year,reflecting the difference between the controlled factors of trunk growth and canopy growth.The tree ring width index is only positively correlated with NDVI in July.Coniferous trees reflect part of NDVI changes.The influencing factors of NDVI in the three parallel rivers area are complex and diverse.
