2010 10 October2010 5 FOREST RESOURCESMANAGEMENT No1 5 马 旺, 谷建才, 陈 平, 谭绪泉, 赵 上 (, 071000) : 运用逐步回归分析方法, 对辽河源地区油松生 与气象因子之间的关系进行分析, 结果表明: 影响油松胸 径生 量的主导气象因子是年蒸发量年日照时数和年降雨量; 影响油松树高生 量的主导气象因子是年日照 时数年蒸发量和年降雨量由此可知, 对辽河源地区油松生 量影响较大的气象因子是年蒸发量年日照时 数和年降雨量 : 油松;气象因子; 相关分析;辽河源地区 : S716; S7911 15 :A : 1002- 6622(2010) 05- 0065- 05 Research on the Relationship between Tree Grow th and C limatic Factors of Pinustabulaeform is in the Source Areas of the L iaohe River MA ang, GU Jianca,i CHENG Ping,TAN Xuquan, ZHAO Shang (H ebeiAgricultural University, Baoding 071000,H ebeiProvince, China) Abstract: In this study, the stepwise regressionmethod is used to explore the relationship between tree growth and clmi aticfactorsofPinustabulaeformis in the source areasof theLiaoheRiver1Results indicated that the dominantfactorsnotably influencing the radialgrowth of Pinustabulaeformis are annual evapora- tion, annualsunshinedurationandyearly precipitation; themajor factorsobviously influencing the elonga- tion growth ofPinustabulaeformis stem are annual evaporation, annual sunshine duration and yearly pre- cipitation1Thus,we can conclude that the clmi atic factorshaving a noticeable effect on the growth of P-i nustabulaeformisare annual evaporation, annual sunshine duration and yearly precipitation1 K ey words: Pinustabulaeformis, clmi atic factor, correlation analysis, the source areasof theLiaoheRiver [ 1] (Pinus tabulafeorm is),, , , , ,
