摘　　要：通过长白落叶松种源试验的结果,揭示了长白落叶松的地理变异规律与模式。主要特点是:呈现纬向为主,经向为辅,经纬双重正向的渐变模式。影响长白落叶松地理变异的主导气候因子是温度,其次为水份。利用长白落叶松种源生长与其环境因子线性相关显著的性状,采用主分量分析方法,将长白落叶松划分成四大种源区,即白刀山种源区(编号Ⅰ)、小北湖种源区(编号Ⅱ)大石头种源区编号(Ⅲ)、和白河种源区(编号Ⅳ)。This Paper concerns Larix olgensis rules and models of geographic variations on basic result of its provenance test. Its character is gradual variance model of the latitude variation as domenant and longitute variations as complement. Im portant climatic factors of effecting geography variations of Larix olgensis is tempreture, second one is water. Basis on sufficent linear correlation betwen provenance growth and environment factors by principal component analysis method, the natural provenance area of larix olgensis was divised into four provenance regions, as: Baidaoshan provenance region(No.1), Xiaobeihu provenance region(No.2), Dashitou provenance region(No.3), Baihe provenance region(No.4).
