摘　　要：１９８６年～１９９３年，采用固定标准地法，调查研究了大兴安岭塔河地区兴安落叶松天然林的生长。结果表明：幼、中龄兴安落叶松天然林材积定期平均生长量分别是５．６８、３．７５ｍ３／（ｈｍ２·ａ）；成熟林的生长量约１．５９ｍ３／（ｈｍ２·ａ）。草类—落叶松林的生长量平均值最大（包括溪旁—落叶松林），４０年生左右林分的材积定期平均生长量是５．３６ｍ３／（ｈｍ２·ａ），以下依次为杜鹃—落叶松林、杜香—落叶松林。The growth of natural forests of larix gmelinii in Tahe Forestry Bureau.Daxingan Mountain District was measured in perpetual plots. Results showed that: (1) Periodically average increment of volume reached 5. 68. 3. 75 m3/ (hm2· a) for young forests and middle aged forests and about 1. 59 m3/(hm2· a) for mature forests. (2) The order of forest types from high increment of volume to low increment of that was: herbs-larch forest. about 5. 36 m3/(hm2. a) of periodically average increment of volume at 40 ages, including, larch forest along stream, azalea (Rhododendron dahuricum)- larch forest. ledum-larch forest.
