本文研究了落叶松的平均繁殖年龄、最大繁殖年龄和最小繁殖年龄，并讨论了繁殖年龄与环境因子的关系。结果表明：平均生殖年龄为78.59岁，最小生殖年龄为26岁，最大生殖年龄为208岁。南坡平均繁殖年龄为72.97岁，最小繁殖年龄为26岁，最大繁殖年龄为153岁。北坡平均繁殖年龄为92岁，最小繁殖年龄为29岁，最大繁殖年龄为208岁。平均繁殖年龄与海拔高度和年降水量呈正相关，最大繁殖年龄与坡度呈正相关，与最小繁殖年龄负相关，说明繁殖越早，繁殖时间越短。
The average reproduction age、maximum reproduction age and minimum reproduction age of Larix chinensis were studied in this paper, the relationships between the reproduction age and the environment factors were also discussed. The result shows that the average reproduction age was 78.59 years, the minimum reproduction age was 26 years, and the maximum reproduction age was 208 years. In South Slope, the average reproduction age was 72.97 years, the minimum reproduction age was 26 years, and the maximum reproduction age was 153 years. In North Slope, the average reproduction age was 92 years, the minimum reproduction age was 29 years, and the maximum reproduction age was 208 years. The average reproduction age shows positive correlation to altitude and annual precipitation, the maximum reproduction age was positive correlation to slope and negative correlation to the minimum reproduction age, this shows that the earlier reproduction decrease the time of reproduction.
