【摘要】 运用多元逐步回归分析法分析油松生长与气候因子的关系，结果表明：油松是对气候因子反应敏感的树种；气候因子间是相互影响、相互制约、共同起作用的。影响油松树高、胸径、材积连年生长的主导气候因子分别为：降水量和≥１０°积温；降水量、≥１０°积温和光照时数；降水量、光照时数和≥１０°积温。更多还原

【Abstract】 The relation between the growth of chinese pine(GCP)and climatic factors(CF)isanalysed by using multivariate regression.The results showed that chinese pine is a kind of treewhich respond sensitively to CF.There are mutual effects among CF. and CF effect GCP to-gether. The dominant CF which influence on the successive annal growth of heigh,diameter andvolume of chinese pine are precipitation and≥10℃acctimulative air temperature;precipitation. ≥10℃ accumulative air temperature and sunligh hours. precipitation. sunligh hours and≥10℃accumulative air temperature. respectively.更多还原
