| 摘 要： | 对小坑林场杉木初级种子园历年结实量与气候、管理等14个因子进行逐步回归分析，结果表明，种子园种子年产量、球果年产量与3月中旬平均气温（x7）存在指数函数关系。其公式为：y种子＝e^0.6184757 0.2414992x7,y球果＝e^4.712797 0.1980816x。据此提出了相应的营林措施。 |
| 关 键 词： | 杉木 种子园 种子年产量 球果年产量 旬平均气温 指数函数关系 |

| Abstract: | The paper analyzed the relationship between seed yield and 14 factors of climate and management in primary Chinese fir seed orchard in Xiaokeng Forest Farm using stepwise regression method. The results show that average temperature in middle of March ( x 7) is critical to seed and cone yield. Their relationship can express as exponential functional equations: seed =e 0.618 475 7+0.241 499 2 x 7 , cone =e 4.712 797+0.198 081 6 x 7 .Base on the results, the paper also raises some proposals on the seed orchard management. |
| Keywords: | Chinese fir seed orchard annual seed yield annual cone yield the ten day average temperature |
