摘要/Abstract

摘要： 对机械整地、人工整地方式下塞罕坝华北落叶松人工林林分生长、生物量及生产力进行了研究,结果表明:机械整地条件下,34a生林分生物量为166.94t/hm²,人工整地条件下,34a生林分生物量为155.08t/hm²,可见采用机械整地方式可以比人工整地方式提高林木生物量7.65%;不同整地方式下,华北落叶松各组分的含碳量差别较小,树干的含碳量大约45.00t/hm²,大约占总碳储量的50.00%;通过对不同整地方式下生产力的比较,得出采用机械整地方式可以比人工整地方式提高华北落叶松人工林平均生产力12.40％。

关键词: 华北落叶松人工林, 整地方式, 生物量, 生产力

Abstract: Larix principis-rupprechtii plantation growth conditions,biomass and productivity under diffe-rent site preparation mode were investigated.The results show that successive diameter trees,mean diameter growth increment under mechanical soil preparation conditions is greater than manual site preparation;the total forest tree layer biomass per hectare change is 166.94 t (34a) under mechanical soil preparation condition,the total forest tree layer biomass change is 156.34 t/hm² (35a) under manual site preparation,stand biomass of mechanical soil preparation condition is larger than manual site preparation.Under different soil preparation modes,carbon content of each component has small difference,the carbon content of the trunk is in about 45t/hm²,approximately 50% of the total carbon storage.Carbon content of each component and productivity under mechanical site preparation is larger.Mechanical site preparation can increase average productivity 12.4% more than manual site preparation.

Key words: Larix principis-rupprechtii plantation, site preparation mode, biomass, productivity
