摘要: 采用比较分析与野外调查的方法,对沙地樟子松人工林天然更新特征进行了研究.能够进行天然更新的引种地区天然更新在时间上是不连续的,与特定年份的某些降水因子密切相关;在空间上主要有3种更新方式:林隙更新、林缘更新、阔叶林下更新;天然更新幼树生长情况与人工林的生长差异不大.

Abstract: By employing comparison analysis and field survey, the natural regeneration of Mongolian pine plantations on sandy soil was investigated. In plantation areas where regeneration can take place naturally, natural regeneration of Mongolian pine varied temporally and spatially. Natural regeneration wasn't temporally continuous; it had a close relationship with autumn precipitation in particular years. In spatial aspect, there were three regeneration types: regeneration in forest gaps, regeneration on edges of a forest, regeneration under young broadleaf forest. There was no significant difference between the growth of regeneration saplings and plantation trees.
