| 摘 要： | 以镇平等２０个县的１５个气候生态因子连续１０ａ的观测资料为基础，对灰色关联分析在林木引种中应用的可行性进行了分析。结果表明，灰色关联分析可定量地说明林木引种点与原产地之间的气候相似程度，并能在种源或品种的筛选和引种效果的综合评判中应用一个简单、直观的数量指标来表示研究结果。为树木引种提供了一种限制条件少、计算简单、结果直观的分析方法。

| Abstract: | Based on the 10-year precipitation series of 20 counties in Henan Province,thefeasibility of the application of grey correlative analysis to the introduction of forestry treewas evaluated. The results showed that grey correlative analysis could quantitatively indi-cate the similarity between the native area and the introducing land,and directly express bya figure the results of variety contrast test or that of introduction's multi-point test.Theresults provided an easy method with fewer limitation factors for the exotic tree study. |
