摘    要:用逐步回归方法,分析了塞罕坝地区华北落叶松生长与气候因子的相关关系。结果表明:①影响华北落叶松胸径、树高连年生长的主导气候因子分别为≥10℃的有效积温和年平均气温、上年11月—当年1月的平均蒸发量;②气候因子间是相互影响、相互制约、共同作用的,并通过单优势性、协同作用、拮抗作用等形式对华北落叶松生长产生直接和间接影响。 

关 键 词:塞罕坝自然保护区   华北落叶松   气候因子   相关分析

Abstract:The relations between the growth of Larix principis rupprechtii and climatic factors were analyzed by stepwise regression method. The results showed that: 1)the dominant climatic factors influencing the successive annual growth of diameter and height of L. principis rupprechtii were ≥10℃ effective accumulated temperature,annual mean temperature and the mean evaporation from November of previous year to January of present year;2)there were mutual influence, mutual restriction and interaction among climatic factors. Those factors affected L. principis rupprechtii directly and indirectly by the forms of single advantage, synergistic effect and antagonism.
Keywords:Saihanba Nature Reserve  Larix principis-rupprechtii  climatic factors  correlated analysis
