| 摘 要： | 本文以５年生红松种源为试验材料，采用方差分析，综合指数选择等方法，证明红松不同地理种源间的差异是极显著的。文章还通过采用９个不同数学模型，拟合了１１个种源在纬度或经度上的一维地理变异趋势。经二维多项高次趋势分析，将红松１１个地理种源划分为３个渐变群。

| Abstract: | This paper describes the genetic difference of Pinus koraiensis provenance with the geographical variation.The material of the test is five years old provenance of it.The result shows that the difference among geographical provenance is exceedingly notalbe by variance analysis and comprehensive index selection.The mathematical models fit the tendency of one-dimensional geographical variation of elevn provenance in tatitude and longitude.Eleven geographical prevenances are divided into three gradually variable species by tendency analysis of two-dimensioal higher-power Polynomial. |
