| 摘 要： | 通过详实的外业调查和细致的内业分析,揭示了天然杨桦林下红松种群天然更新的格局与过程。结果表明:山地杨桦林和山地白桦林下红松更新的数量和质量均优于谷地苔草白桦林,质量高于原始阔叶红松林;红松种群呈聚团状发生,其大发生时期晚于杨桦种群大发生时期;各龄红松的生长受不同林分结构因子的制约;人为透光抚育可以加快红松种群的更新进程,提高红松更新质量;建立上层白桦较下层红松大适宜年龄的更新复合体是可行的。

| Abstract: | The characteristics of natural Poplar-Birch forest, the features of the regeneration and the growth of Korean Pine population under forest,and the relationship between upper structure of Poplar-White Birch and regeneration quality of Korean Pine population under forest were studied in the paper. It is shown that the regeneration quantity and quality of Koran Pine population under Mountain Poplar-White Birch forest and White Birch forest is better than that under irgin Korean Pine forest; the distribution pattern of Korean Pine population belong to custer distribution, and the period during which Korean Pine population occures largely is always behind the period of the mass-occurence of Poplar and White birch population; the factors affacting regeneration of Korean Pine population are different at every age stage; the partial removal of White Birch in over story can accelerate the regeneration process and improve the regeneration quality of Korean Pine in low story. |
