对九台市上河湾林场1997年营造的长白落叶松人工林进行抚育间伐试验,结果表明:间伐3 a后,间伐和未间伐的林分密度分别为2150株· hm-2和3150株· hm-2,平均胸径分别为11.0 cm和9.3 cm,总蓄积分别为119.6 m3· hm-2和89.0 m3· hm-2。对长白落叶松人工林进行合理抚育间伐,可显著提高林分质量和生长量及经济效益。
對九檯市上河灣林場1997年營造的長白落葉鬆人工林進行撫育間伐試驗,結果錶明:間伐3 a後,間伐和未間伐的林分密度分彆為2150株· hm-2和3150株· hm-2,平均胸徑分彆為11.0 cm和9.3 cm,總蓄積分彆為119.6 m3· hm-2和89.0 m3· hm-2。對長白落葉鬆人工林進行閤理撫育間伐,可顯著提高林分質量和生長量及經濟效益。

Intermediate cutting test of man -made forest of Larix olgensis Henry planted in 1997 was taken in Shanghewan forest farm of Jiutai city , results indicated that 3 years after intermediate cutting , stand density of intermediate cutting and no intermediate cutting was 2 150· hm-2 and 3 150· hm-2 , respectively, average DBH was 11.0 cm and 9.3 cm, total accumulation was 119.6 m3 · hm-2 and 89.0 m3 · hm-2 .Intermediate cutting may significantly increase forest stand quali-ty, growth and economic benefit of man -made forest of Larix olgensis Henry.
