摘要
通过对 2 0多年来 ENSO事件的发生与杉木人工林胸径生长关系的研究 ,探讨全球气候异常对林木生长动态的影响。结果表明 :厄尔尼诺及南方涛动对杉木人工林胸径生长存在显著影响 ( α=0 .1 0 )。以南方涛动为自变量 ,建立杉木人工林胸径生长模型 ,模拟精度达93.61 % ,为林木生长预测提供了新途径。
According to the analysis of relationship between the ENSO event and the D.B.H. growth of Chinese fir in the past 20 years,the effects of global climate abnormality on the growth of Chinese fir was discussed.The results showed that the (inverse) ElNi n o and the Southern Oscillation Index (SOI) both affected the D.B.H.growth of Chinese fir significantly (α=0.10).The D.B.H.growth model of Chinese fir was established while the SOI was regarded as variables,the simulating precision of the model reached 93.61%,which would provide a new method for predicting tree growth.
