摘要: 在分析固沙林经营目的的基础上,提出了该林种的防护成熟定义,用郁闭度(覆盖度)达到π/4为成熟的主要特征,通过冠幅与胸径、胸径与年龄的关系确定防护成熟龄;此外以初始成熟龄和更新龄为时间界限将林分分成3个经营时期:郁闭前期、防护成熟期和更新期,并提出了各个时期相应的经营对策。

关键词: 固沙林, 防护成熟, 更新

Abstract: The definition of protective maturity of sand-fixing forest has been put forwards on the basis of its managemental purpose.Having the major maturity character with canopy coverage reaching π/4,the protective maturity age is determined by the relationships between canopy width and diameter at breast height(DBH),DBH and age.Divided by the initial protective maturity age(AIPM) and regeneration age,the period of forest management falls into 3 stages:pre-maturity stage,protective maturity stage and regeneration stage.Meanwhile,the measurements of management corresponding to the three stages have been suggested in the paper.

Key words: Sand-fixation forest, Protective maturity, Regeneration
